Summary

Southern Bluefin Tuna (SBT) is a major contributor to the Australian aquaculture industry, however at the moment it is reliant on the on-growing of wild-caught juveniles to market size. The recent captive-spawning of SBT by Clean Seas Tuna Ltd. (CST) has opened up the potential for the aquaculture of this high market species. Early attempts at production of SBT have identified a number of culture bottlenecks, predominantly associated with larval culture. Elucidation of the visual system and factors that promote first feeding success in SBT are critical to gain a thorough understanding of culture strategies that will work for this species. Due to the novelty and the limited spawning season of SBT one of the most effective tools to use to rapidly develop culture methods is to gain knowledge of successful strategies with comparative animals. This is the case with Yellowfin Tuna (YFT).

This research travel grant allowed travel to the 8th annual workshop on physiology and aquaculture of pelagics with emphasis on reproduction and early developmental stages of Yellowfin Tuna, Thunnus albacares held at the Achotines Laboratory, Republic of Panama, Central America, 7-19 June 2010. A large amount of knowledge is available due to the Achotines Laboratory having a domesticated spawning population of YFT releasing viable gametes every day of the year. Attendance of this workshop provided invaluable exposure to leading researchers and professionals in the tuna field and exposed the author to the latest trends in tuna aquaculture which may be directly applied to the PhD research program as well as to larval rearing at CST.

Summary

Southern Bluefin Tuna (SBT) is a major contributor to the Australian aquaculture industry, however at the moment it is reliant on the on-growing of wild-caught juveniles to market size. The recent captive-spawning of SBT by Clean Seas Tuna Ltd. (CST) has opened up the potential for the aquaculture of this high market species. Early attempts at production of SBT have identified a number of culture bottlenecks, predominantly associated with larval culture. Elucidation of the visual system and factors that promote first feeding success in SBT are critical to gain a thorough understanding of culture strategies that will work for this species. Due to the novelty and the limited spawning season of SBT one of the most effective tools to use to rapidly develop culture methods is to gain knowledge of successful strategies with comparative animals. This is the case with Yellowfin Tuna (YFT).

Summary

Southern Bluefin Tuna (SBT) is a major contributor to the Australian aquaculture industry, however at the moment it is reliant on the on-growing of wild-caught juveniles to market size. The recent captive-spawning of SBT by Clean Seas Tuna Ltd. (CST) has opened up the potential for the aquaculture of this high market species. Early attempts at production of SBT have identified a number of culture bottlenecks, predominantly associated with larval culture. Elucidation of the visual system and factors that promote first feeding success in SBT are critical to gain a thorough understanding of culture strategies that will work for this species. Due to the novelty and the limited spawning season of SBT one of the most effective tools to use to rapidly develop culture methods is to gain knowledge of successful strategies with comparative animals. This is the case with Yellowfin Tuna (YFT).

This research travel grant allowed travel to the 8th annual workshop on physiology and aquaculture of pelagics with emphasis on reproduction and early developmental stages of Yellowfin Tuna, Thunnus albacares held at the Achotines Laboratory, Republic of Panama, Central America, 7-19 June 2010. A large amount of knowledge is available due to the Achotines Laboratory having a domesticated spawning population of YFT releasing viable gametes every day of the year. Attendance of this workshop provided invaluable exposure to leading researchers and professionals in the tuna field and exposed the author to the latest trends in tuna aquaculture which may be directly applied to the PhD research program as well as to larval rearing at CST.

The recent captive-spawning of SBT by Clean Seas Tuna Ltd. (CST) has opened up the potential for the aquaculture of this high market species. Early attempts at production of SBT have identified a number of culture bottlenecks, predominantly associated with larval culture. Elucidation of the visual system and factors that promote first feeding success in SBT are critical to gain a thorough understanding of culture strategies that will work for this species. Due to the novelty and the limited spawning season of SBT one of the most effective tools to use to rapidly develop culture methods is to gain knowledge of successful strategies with comparative animals. This is the case with Yellowfin Tuna (YFT).

This research travel grant allowed travel to the 8th annual workshop on physiology and aquaculture of pelagics with emphasis on reproduction and early developmental stages of Yellowfin Tuna, Thunnus albacares held at the Achotines Laboratory, Republic of Panama, Central America, 7-19 June 2010. A large amount of knowledge is available due to the Achotines Laboratory having a domesticated spawning population of YFT releasing viable gametes every day of the year. Attendance of this workshop provided invaluable exposure to leading researchers and professionals in the tuna field and exposed the author to the latest trends in tuna aquaculture which may be directly applied to the PhD research program as well as to larval rearing at CST.

Due to the novelty and the limited spawning season of SBT one of the most effective tools to use to rapidly develop culture methods is to gain knowledge of successful strategies with comparative animals. This is the case with Yellowfin Tuna (YFT).

This research travel grant allowed travel to the 8th annual workshop on physiology and aquaculture of pelagics with emphasis on reproduction and early developmental stages of Yellowfin Tuna, Thunnus albacares held at the Achotines Laboratory, Republic of Panama, Central America, 7-19 June 2010. A large amount of knowledge is available due to the Achotines Laboratory having a domesticated spawning population of YFT releasing viable gametes every day of the year. Attendance of this workshop provided invaluable exposure to leading researchers and professionals in the tuna field and exposed the author to the latest trends in tuna aquaculture which may be directly applied to the PhD research program as well as to larval rearing at CST.

Summary

Southern Bluefin Tuna (SBT) is a major contributor to the Australian aquaculture industry, however at the moment it is reliant on the on-growing of wild-caught juveniles to market size. The recent captive-spawning of SBT by Clean Seas Tuna Ltd. (CST) has opened up the potential for the aquaculture of this high market species. Early attempts at production of SBT have identified a number of culture bottlenecks, predominantly associated with larval culture. Elucidation of the visual system and factors that promote first feeding success in SBT are critical to gain a thorough understanding of culture strategies that will work for this species.

This research travel grant allowed travel to the 8th annual workshop on physiology and aquaculture of pelagics with emphasis on reproduction and early developmental stages of Yellowfin Tuna, Thunnus albacares held at the Achotines Laboratory, Republic of Panama, Central America, 7-19 June 2010. A large amount of knowledge is available due to the Achotines Laboratory having a domesticated spawning population of YFT releasing viable gametes every day of the year. Attendance of this workshop provided invaluable exposure to leading researchers and professionals in the tuna field and exposed the author to the latest trends in tuna aquaculture which may be directly applied to the PhD research program as well as to larval rearing at CST.

Summary

Southern Bluefin Tuna (SBT) is a major contributor to the Australian aquaculture industry, however at the moment it is reliant on the on-growing of wild-caught juveniles to market size. The recent captive-spawning of SBT by Clean Seas Tuna Ltd. (CST) has opened up the potential for the aquaculture of this high market species. Early attempts at production of SBT have identified a number of culture bottlenecks, predominantly associated with larval culture. Elucidation of the visual system and factors that promote first feeding success in SBT are critical to gain a thorough understanding of culture strategies that will work for this species. Due to the novelty and the limited spawning season of SBT one of the most effective tools to use to rapidly develop culture methods is to gain knowledge of successful strategies with comparative animals. This is the case with Yellowfin Tuna (YFT).

Summary

Southern Bluefin Tuna (SBT) is a major contributor to the Australian aquaculture industry, however at the moment it is reliant on the on-growing of wild-caught juveniles to market size. The recent captive-spawning of SBT by Clean Seas Tuna Ltd. (CST) has opened up the potential for the aquaculture of this high market species. Early attempts at production of SBT have identified a number of culture bottlenecks, predominantly associated with larval culture. Elucidation of the visual system and factors that promote first feeding success in SBT are critical to gain a thorough understanding of culture strategies that will work for this species. Due to the novelty and the limited spawning season of SBT one of the most effective tools to use to rapidly develop culture methods is to gain knowledge of successful strategies with comparative animals. This is the case with Yellowfin Tuna (YFT).

Summary

Southern Bluefin Tuna (SBT) is a major contributor to the Australian aquaculture industry, however at the moment it is reliant on the on-growing of wild-caught juveniles to market size. The recent captive-spawning of SBT by Clean Seas Tuna Ltd. (CST) has opened up the potential for the aquaculture of this high market species. Early attempts at production of SBT have identified a number of culture bottlenecks, predominantly associated with larval culture. Elucidation of the visual system and factors that promote first feeding success in SBT are critical to gain a thorough understanding of culture strategies that will work for this species. Due to the novelty and the limited spawning season of SBT one of the most effective tools to use to rapidly develop culture methods is to gain knowledge of successful strategies with comparative animals. This is the case with Yellowfin Tuna (YFT).

This research travel grant allowed travel to the 8th annual workshop on physiology and aquaculture of pelagics with emphasis on reproduction and early developmental stages of Yellowfin Tuna, Thunnus albacares held at the Achotines Laboratory, Republic of Panama, Central America, 7-19 June 2010. A large amount of knowledge is available due to the Achotines Laboratory having a domesticated spawning population of YFT releasing viable gametes every day of the year. Attendance of this workshop provided invaluable exposure to leading researchers and professionals in the tuna field and exposed the author to the latest trends in tuna aquaculture which may be directly applied to the PhD research program as well as to larval rearing at CST.

The recent captive-spawning of SBT by Clean Seas Tuna Ltd. (CST) has opened up the potential for the aquaculture of this high market species. Early attempts at production of SBT have identified a number of culture bottlenecks, predominantly associated with larval culture. Elucidation of the visual system and factors that promote first feeding success in SBT are critical to gain a thorough understanding of culture strategies that will work for this species. Due to the novelty and the limited spawning season of SBT one of the most effective tools to use to rapidly develop culture methods is to gain knowledge of successful strategies with comparative animals. This is the case with Yellowfin Tuna (YFT).

This research travel grant allowed travel to the 8th annual workshop on physiology and aquaculture of pelagics with emphasis on reproduction and early developmental stages of Yellowfin Tuna, Thunnus albacares held at the Achotines Laboratory, Republic of Panama, Central America, 7-19 June 2010. A large amount of knowledge is available due to the Achotines Laboratory having a domesticated spawning population of YFT releasing viable gametes every day of the year. Attendance of this workshop provided invaluable exposure to leading researchers and professionals in the tuna field and exposed the author to the latest trends in tuna aquaculture which may be directly applied to the PhD research program as well as to larval rearing at CST.

Due to the novelty and the limited spawning season of SBT one of the most effective tools to use to rapidly develop culture methods is to gain knowledge of successful strategies with comparative animals. This is the case with Yellowfin Tuna (YFT).

This research travel grant allowed travel to the 8th annual workshop on physiology and aquaculture of pelagics with emphasis on reproduction and early developmental stages of Yellowfin Tuna, Thunnus albacares held at the Achotines Laboratory, Republic of Panama, Central America, 7-19 June 2010. A large amount of knowledge is available due to the Achotines Laboratory having a domesticated spawning population of YFT releasing viable gametes every day of the year. Attendance of this workshop provided invaluable exposure to leading researchers and professionals in the tuna field and exposed the author to the latest trends in tuna aquaculture which may be directly applied to the PhD research program as well as to larval rearing at CST.

Summary

Southern Bluefin Tuna (SBT) is a major contributor to the Australian aquaculture industry, however at the moment it is reliant on the on-growing of wild-caught juveniles to market size. The recent captive-spawning of SBT by Clean Seas Tuna Ltd. (CST) has opened up the potential for the aquaculture of this high market species. Early attempts at production of SBT have identified a number of culture bottlenecks, predominantly associated with larval culture. Elucidation of the visual system and factors that promote first feeding success in SBT are critical to gain a thorough understanding of culture strategies that will work for this species.

This research travel grant allowed travel to the 8th annual workshop on physiology and aquaculture of pelagics with emphasis on reproduction and early developmental stages of Yellowfin Tuna, Thunnus albacares held at the Achotines Laboratory, Republic of Panama, Central America, 7-19 June 2010. A large amount of knowledge is available due to the Achotines Laboratory having a domesticated spawning population of YFT releasing viable gametes every day of the year. Attendance of this workshop provided invaluable exposure to leading researchers and professionals in the tuna field and exposed the author to the latest trends in tuna aquaculture which may be directly applied to the PhD research program as well as to larval rearing at CST.

Summary

Southern Bluefin Tuna (SBT) is a major contributor to the Australian aquaculture industry, however at the moment it is reliant on the on-growing of wild-caught juveniles to market size. The recent captive-spawning of SBT by Clean Seas Tuna Ltd. (CST) has opened up the potential for the aquaculture of this high market species. Early attempts at production of SBT have identified a number of culture bottlenecks, predominantly associated with larval culture. Elucidation of the visual system and factors that promote first feeding success in SBT are critical to gain a thorough understanding of culture strategies that will work for this species. Due to the novelty and the limited spawning season of SBT one of the most effective tools to use to rapidly develop culture methods is to gain knowledge of successful strategies with comparative animals. This is the case with Yellowfin Tuna (YFT).

Summary

Southern Bluefin Tuna (SBT) is a major contributor to the Australian aquaculture industry, however at the moment it is reliant on the on-growing of wild-caught juveniles to market size. The recent captive-spawning of SBT by Clean Seas Tuna Ltd. (CST) has opened up the potential for the aquaculture of this high market species. Early attempts at production of SBT have identified a number of culture bottlenecks, predominantly associated with larval culture. Elucidation of the visual system and factors that promote first feeding success in SBT are critical to gain a thorough understanding of culture strategies that will work for this species. Due to the novelty and the limited spawning season of SBT one of the most effective tools to use to rapidly develop culture methods is to gain knowledge of successful strategies with comparative animals. This is the case with Yellowfin Tuna (YFT).

Summary

Southern Bluefin Tuna (SBT) is a major contributor to the Australian aquaculture industry, however at the moment it is reliant on the on-growing of wild-caught juveniles to market size. The recent captive-spawning of SBT by Clean Seas Tuna Ltd. (CST) has opened up the potential for the aquaculture of this high market species. Early attempts at production of SBT have identified a number of culture bottlenecks, predominantly associated with larval culture. Elucidation of the visual system and factors that promote first feeding success in SBT are critical to gain a thorough understanding of culture strategies that will work for this species. Due to the novelty and the limited spawning season of SBT one of the most effective tools to use to rapidly develop culture methods is to gain knowledge of successful strategies with comparative animals. This is the case with Yellowfin Tuna (YFT).

This research travel grant allowed travel to the 8th annual workshop on physiology and aquaculture of pelagics with emphasis on reproduction and early developmental stages of Yellowfin Tuna, Thunnus albacares held at the Achotines Laboratory, Republic of Panama, Central America, 7-19 June 2010. A large amount of knowledge is available due to the Achotines Laboratory having a domesticated spawning population of YFT releasing viable gametes every day of the year. Attendance of this workshop provided invaluable exposure to leading researchers and professionals in the tuna field and exposed the author to the latest trends in tuna aquaculture which may be directly applied to the PhD research program as well as to larval rearing at CST.

The recent captive-spawning of SBT by Clean Seas Tuna Ltd. (CST) has opened up the potential for the aquaculture of this high market species. Early attempts at production of SBT have identified a number of culture bottlenecks, predominantly associated with larval culture. Elucidation of the visual system and factors that promote first feeding success in SBT are critical to gain a thorough understanding of culture strategies that will work for this species. Due to the novelty and the limited spawning season of SBT one of the most effective tools to use to rapidly develop culture methods is to gain knowledge of successful strategies with comparative animals. This is the case with Yellowfin Tuna (YFT).

This research travel grant allowed travel to the 8th annual workshop on physiology and aquaculture of pelagics with emphasis on reproduction and early developmental stages of Yellowfin Tuna, Thunnus albacares held at the Achotines Laboratory, Republic of Panama, Central America, 7-19 June 2010. A large amount of knowledge is available due to the Achotines Laboratory having a domesticated spawning population of YFT releasing viable gametes every day of the year. Attendance of this workshop provided invaluable exposure to leading researchers and professionals in the tuna field and exposed the author to the latest trends in tuna aquaculture which may be directly applied to the PhD research program as well as to larval rearing at CST.

Due to the novelty and the limited spawning season of SBT one of the most effective tools to use to rapidly develop culture methods is to gain knowledge of successful strategies with comparative animals. This is the case with Yellowfin Tuna (YFT).

This research travel grant allowed travel to the 8th annual workshop on physiology and aquaculture of pelagics with emphasis on reproduction and early developmental stages of Yellowfin Tuna, Thunnus albacares held at the Achotines Laboratory, Republic of Panama, Central America, 7-19 June 2010. A large amount of knowledge is available due to the Achotines Laboratory having a domesticated spawning population of YFT releasing viable gametes every day of the year. Attendance of this workshop provided invaluable exposure to leading researchers and professionals in the tuna field and exposed the author to the latest trends in tuna aquaculture which may be directly applied to the PhD research program as well as to larval rearing at CST.

Summary

Southern Bluefin Tuna (SBT) is a major contributor to the Australian aquaculture industry, however at the moment it is reliant on the on-growing of wild-caught juveniles to market size. The recent captive-spawning of SBT by Clean Seas Tuna Ltd. (CST) has opened up the potential for the aquaculture of this high market species. Early attempts at production of SBT have identified a number of culture bottlenecks, predominantly associated with larval culture. Elucidation of the visual system and factors that promote first feeding success in SBT are critical to gain a thorough understanding of culture strategies that will work for this species.

Summary

Barramundi is naturally a mass spawning species, which can be induced to spawn in captivity under conditions that attempt to replicate the natural environment. The Australian Barramundi industry has on hand a large number of mature broodstock that are currently supplying the grow-out market, however, before selective breeding programs can begin, it is important to assess the levels of genetic diversity and relatedness of current captive broodstock populations.

Mass spawning hatchery practices using small broodstock populations, in addition to the cannibalistic nature of some fish species, contribute to a reduction of genetic diversity from parent to offspring and throughout the juvenile grow-out stages. This is of concern when establishing a selective breeding program for such species because the genetic diversity that is captured in the start-up and initial generations of the program is the basic ingredient for future genetic improvement. The aim of this thesis was to examine methods for capturing and conserving genetic diversity in mass spawning Barramundi (Lates calcarifer), when constructing a base population for a long-term selective breeding program for the species.

The results suggest that a mass spawning group of at least 30 Barramundi individuals is required to achieve a high participation rate of breeders and to limit the loss of genetic variation transferred to the offspring. Options for selecting candidates to compose a founding population were explored, and recommendations made to promote the longevity and impact of a selective breeding program for Barramundi.

The aim of this thesis was to examine methods for capturing and conserving genetic diversity in mass spawning Barramundi (Lates calcarifer), when constructing a base population for a long-term selective breeding program for the species.

The results suggest that a mass spawning group of at least 30 Barramundi individuals is required to achieve a high participation rate of breeders and to limit the loss of genetic variation transferred to the offspring. Options for selecting candidates to compose a founding population were explored, and recommendations made to promote the longevity and impact of a selective breeding program for Barramundi.

Summary

Barramundi is naturally a mass spawning species, which can be induced to spawn in captivity under conditions that attempt to replicate the natural environment. The Australian Barramundi industry has on hand a large number of mature broodstock that are currently supplying the grow-out market, however, before selective breeding programs can begin, it is important to assess the levels of genetic diversity and relatedness of current captive broodstock populations.

Mass spawning hatchery practices using small broodstock populations, in addition to the cannibalistic nature of some fish species, contribute to a reduction of genetic diversity from parent to offspring and throughout the juvenile grow-out stages. This is of concern when establishing a selective breeding program for such species because the genetic diversity that is captured in the start-up and initial generations of the program is the basic ingredient for future genetic improvement. The aim of this thesis was to examine methods for capturing and conserving genetic diversity in mass spawning Barramundi (Lates calcarifer), when constructing a base population for a long-term selective breeding program for the species.

The results suggest that a mass spawning group of at least 30 Barramundi individuals is required to achieve a high participation rate of breeders and to limit the loss of genetic variation transferred to the offspring. Options for selecting candidates to compose a founding population were explored, and recommendations made to promote the longevity and impact of a selective breeding program for Barramundi.

The Australian Barramundi industry has on hand a large number of mature broodstock that are currently supplying the grow-out market, however, before selective breeding programs can begin, it is important to assess the levels of genetic diversity and relatedness of current captive broodstock populations.

Mass spawning hatchery practices using small broodstock populations, in addition to the cannibalistic nature of some fish species, contribute to a reduction of genetic diversity from parent to offspring and throughout the juvenile grow-out stages. This is of concern when establishing a selective breeding program for such species because the genetic diversity that is captured in the start-up and initial generations of the program is the basic ingredient for future genetic improvement. The aim of this thesis was to examine methods for capturing and conserving genetic diversity in mass spawning Barramundi (Lates calcarifer), when constructing a base population for a long-term selective breeding program for the species.

The results suggest that a mass spawning group of at least 30 Barramundi individuals is required to achieve a high participation rate of breeders and to limit the loss of genetic variation transferred to the offspring. Options for selecting candidates to compose a founding population were explored, and recommendations made to promote the longevity and impact of a selective breeding program for Barramundi.

Barramundi is naturally a mass spawning species, which can be induced to spawn in captivity under conditions that attempt to replicate the natural environment. The Australian Barramundi industry has on hand a large number of mature broodstock that are currently supplying the grow-out market, however, before selective breeding programs can begin, it is important to assess the levels of genetic diversity and relatedness of current captive broodstock populations.

Mass spawning hatchery practices using small broodstock populations, in addition to the cannibalistic nature of some fish species, contribute to a reduction of genetic diversity from parent to offspring and throughout the juvenile grow-out stages. This is of concern when establishing a selective breeding program for such species because the genetic diversity that is captured in the start-up and initial generations of the program is the basic ingredient for future genetic improvement. The aim of this thesis was to examine methods for capturing and conserving genetic diversity in mass spawning Barramundi (Lates calcarifer), when constructing a base population for a long-term selective breeding program for the species.

The results suggest that a mass spawning group of at least 30 Barramundi individuals is required to achieve a high participation rate of breeders and to limit the loss of genetic variation transferred to the offspring. Options for selecting candidates to compose a founding population were explored, and recommendations made to promote the longevity and impact of a selective breeding program for Barramundi.

Barramundi is naturally a mass spawning species, which can be induced to spawn in captivity under conditions that attempt to replicate the natural environment. The Australian Barramundi industry has on hand a large number of mature broodstock that are currently supplying the grow-out market, however, before selective breeding programs can begin, it is important to assess the levels of genetic diversity and relatedness of current captive broodstock populations.

Mass spawning hatchery practices using small broodstock populations, in addition to the cannibalistic nature of some fish species, contribute to a reduction of genetic diversity from parent to offspring and throughout the juvenile grow-out stages. This is of concern when establishing a selective breeding program for such species because the genetic diversity that is captured in the start-up and initial generations of the program is the basic ingredient for future genetic improvement. The aim of this thesis was to examine methods for capturing and conserving genetic diversity in mass spawning Barramundi (Lates calcarifer), when constructing a base population for a long-term selective breeding program for the species.

The results suggest that a mass spawning group of at least 30 Barramundi individuals is required to achieve a high participation rate of breeders and to limit the loss of genetic variation transferred to the offspring. Options for selecting candidates to compose a founding population were explored, and recommendations made to promote the longevity and impact of a selective breeding program for Barramundi.

Barramundi is naturally a mass spawning species, which can be induced to spawn in captivity under conditions that attempt to replicate the natural environment. The Australian Barramundi industry has on hand a large number of mature broodstock that are currently supplying the grow-out market, however, before selective breeding programs can begin, it is important to assess the levels of genetic diversity and relatedness of current captive broodstock populations.

Mass spawning hatchery practices using small broodstock populations, in addition to the cannibalistic nature of some fish species, contribute to a reduction of genetic diversity from parent to offspring and throughout the juvenile grow-out stages. This is of concern when establishing a selective breeding program for such species because the genetic diversity that is captured in the start-up and initial generations of the program is the basic ingredient for future genetic improvement. The aim of this thesis was to examine methods for capturing and conserving genetic diversity in mass spawning Barramundi (Lates calcarifer), when constructing a base population for a long-term selective breeding program for the species.

The results suggest that a mass spawning group of at least 30 Barramundi individuals is required to achieve a high participation rate of breeders and to limit the loss of genetic variation transferred to the offspring. Options for selecting candidates to compose a founding population were explored, and recommendations made to promote the longevity and impact of a selective breeding program for Barramundi.

Barramundi is naturally a mass spawning species, which can be induced to spawn in captivity under conditions that attempt to replicate the natural environment. The Australian Barramundi industry has on hand a large number of mature broodstock that are currently supplying the grow-out market, however, before selective breeding programs can begin, it is important to assess the levels of genetic diversity and relatedness of current captive broodstock populations.

Mass spawning hatchery practices using small broodstock populations, in addition to the cannibalistic nature of some fish species, contribute to a reduction of genetic diversity from parent to offspring and throughout the juvenile grow-out stages. This is of concern when establishing a selective breeding program for such species because the genetic diversity that is captured in the start-up and initial generations of the program is the basic ingredient for future genetic improvement. The aim of this thesis was to examine methods for capturing and conserving genetic diversity in mass spawning Barramundi (Lates calcarifer), when constructing a base population for a long-term selective breeding program for the species.

The results suggest that a mass spawning group of at least 30 Barramundi individuals is required to achieve a high participation rate of breeders and to limit the loss of genetic variation transferred to the offspring. Options for selecting candidates to compose a founding population were explored, and recommendations made to promote the longevity and impact of a selective breeding program for Barramundi.

Barramundi is naturally a mass spawning species, which can be induced to spawn in captivity under conditions that attempt to replicate the natural environment. The Australian Barramundi industry has on hand a large number of mature broodstock that are currently supplying the grow-out market, however, before selective breeding programs can begin, it is important to assess the levels of genetic diversity and relatedness of current captive broodstock populations.

Mass spawning hatchery practices using small broodstock populations, in addition to the cannibalistic nature of some fish species, contribute to a reduction of genetic diversity from parent to offspring and throughout the juvenile grow-out stages. This is of concern when establishing a selective breeding program for such species because the genetic diversity that is captured in the start-up and initial generations of the program is the basic ingredient for future genetic improvement. The aim of this thesis was to examine methods for capturing and conserving genetic diversity in mass spawning Barramundi (Lates calcarifer), when constructing a base population for a long-term selective breeding program for the species.

The results suggest that a mass spawning group of at least 30 Barramundi individuals is required to achieve a high participation rate of breeders and to limit the loss of genetic variation transferred to the offspring. Options for selecting candidates to compose a founding population were explored, and recommendations made to promote the longevity and impact of a selective breeding program for Barramundi.

Barramundi is naturally a mass spawning species, which can be induced to spawn in captivity under conditions that attempt to replicate the natural environment. The Australian Barramundi industry has on hand a large number of mature broodstock that are currently supplying the grow-out market, however, before selective breeding programs can begin, it is important to assess the levels of genetic diversity and relatedness of current captive broodstock populations.

Mass spawning hatchery practices using small broodstock populations, in addition to the cannibalistic nature of some fish species, contribute to a reduction of genetic diversity from parent to offspring and throughout the juvenile grow-out stages. This is of concern when establishing a selective breeding program for such species because the genetic diversity that is captured in the start-up and initial generations of the program is the basic ingredient for future genetic improvement. The aim of this thesis was to examine methods for capturing and conserving genetic diversity in mass spawning Barramundi (Lates calcarifer), when constructing a base population for a long-term selective breeding program for the species.

The results suggest that a mass spawning group of at least 30 Barramundi individuals is required to achieve a high participation rate of breeders and to limit the loss of genetic variation transferred to the offspring. Options for selecting candidates to compose a founding population were explored, and recommendations made to promote the longevity and impact of a selective breeding program for Barramundi.

Barramundi is naturally a mass spawning species, which can be induced to spawn in captivity under conditions that attempt to replicate the natural environment. The Australian Barramundi industry has on hand a large number of mature broodstock that are currently supplying the grow-out market, however, before selective breeding programs can begin, it is important to assess the levels of genetic diversity and relatedness of current captive broodstock populations.

Mass spawning hatchery practices using small broodstock populations, in addition to the cannibalistic nature of some fish species, contribute to a reduction of genetic diversity from parent to offspring and throughout the juvenile grow-out stages. This is of concern when establishing a selective breeding program for such species because the genetic diversity that is captured in the start-up and initial generations of the program is the basic ingredient for future genetic improvement. The aim of this thesis was to examine methods for capturing and conserving genetic diversity in mass spawning Barramundi (Lates calcarifer), when constructing a base population for a long-term selective breeding program for the species.

The results suggest that a mass spawning group of at least 30 Barramundi individuals is required to achieve a high participation rate of breeders and to limit the loss of genetic variation transferred to the offspring. Options for selecting candidates to compose a founding population were explored, and recommendations made to promote the longevity and impact of a selective breeding program for Barramundi.

Barramundi is naturally a mass spawning species, which can be induced to spawn in captivity under conditions that attempt to replicate the natural environment. The Australian Barramundi industry has on hand a large number of mature broodstock that are currently supplying the grow-out market, however, before selective breeding programs can begin, it is important to assess the levels of genetic diversity and relatedness of current captive broodstock populations.

Mass spawning hatchery practices using small broodstock populations, in addition to the cannibalistic nature of some fish species, contribute to a reduction of genetic diversity from parent to offspring and throughout the juvenile grow-out stages. This is of concern when establishing a selective breeding program for such species because the genetic diversity that is captured in the start-up and initial generations of the program is the basic ingredient for future genetic improvement. The aim of this thesis was to examine methods for capturing and conserving genetic diversity in mass spawning Barramundi (Lates calcarifer), when constructing a base population for a long-term selective breeding program for the species.

The results suggest that a mass spawning group of at least 30 Barramundi individuals is required to achieve a high participation rate of breeders and to limit the loss of genetic variation transferred to the offspring. Options for selecting candidates to compose a founding population were explored, and recommendations made to promote the longevity and impact of a selective breeding program for Barramundi.

Barramundi is naturally a mass spawning species, which can be induced to spawn in captivity under conditions that attempt to replicate the natural environment. The Australian Barramundi industry has on hand a large number of mature broodstock that are currently supplying the grow-out market, however, before selective breeding programs can begin, it is important to assess the levels of genetic diversity and relatedness of current captive broodstock populations.

Mass spawning hatchery practices using small broodstock populations, in addition to the cannibalistic nature of some fish species, contribute to a reduction of genetic diversity from parent to offspring and throughout the juvenile grow-out stages. This is of concern when establishing a selective breeding program for such species because the genetic diversity that is captured in the start-up and initial generations of the program is the basic ingredient for future genetic improvement. The aim of this thesis was to examine methods for capturing and conserving genetic diversity in mass spawning Barramundi (Lates calcarifer), when constructing a base population for a long-term selective breeding program for the species.

The results suggest that a mass spawning group of at least 30 Barramundi individuals is required to achieve a high participation rate of breeders and to limit the loss of genetic variation transferred to the offspring. Options for selecting candidates to compose a founding population were explored, and recommendations made to promote the longevity and impact of a selective breeding program for Barramundi.

Barramundi is naturally a mass spawning species, which can be induced to spawn in captivity under conditions that attempt to replicate the natural environment. The Australian Barramundi industry has on hand a large number of mature broodstock that are currently supplying the grow-out market, however, before selective breeding programs can begin, it is important to assess the levels of genetic diversity and relatedness of current captive broodstock populations.

Mass spawning hatchery practices using small broodstock populations, in addition to the cannibalistic nature of some fish species, contribute to a reduction of genetic diversity from parent to offspring and throughout the juvenile grow-out stages. This is of concern when establishing a selective breeding program for such species because the genetic diversity that is captured in the start-up and initial generations of the program is the basic ingredient for future genetic improvement. The aim of this thesis was to examine methods for capturing and conserving genetic diversity in mass spawning Barramundi (Lates calcarifer), when constructing a base population for a long-term selective breeding program for the species.

The results suggest that a mass spawning group of at least 30 Barramundi individuals is required to achieve a high participation rate of breeders and to limit the loss of genetic variation transferred to the offspring. Options for selecting candidates to compose a founding population were explored, and recommendations made to promote the longevity and impact of a selective breeding program for Barramundi.

Summary

Individual transferable catch quotas (ITQs) were allocated to fishermen in the Australian southern bluefin tuna fishery in 1984. The profitability of the industry increased substantially as a result. This is despite the total Australian catch being halved between 1984 and 1987 due to a decline in the abundance of southern bluefin tuna. The ITQ management system in the fishery was the first in Australia and was amongst the first in the world. Its introduction marked a radical departure from traditional management regimes based on limiting the number of boats allowed to operate and other controls on fishing inputs. These traditional method were, both in Australia and elsewhere, often ineffective in controlling the growth of fishing effort and in generating sustainable long term benefits. A lack of adequate property rights for fishermen over fish stocks has been identified as the major underlying cause of the overexploitation of marine fisheries. By giving fishermen more clearly defined long term property rights in the form of ITQs, incentives for fishermen to conserve the fish stock and to maximise their cost efficiency of harvesting are strengthened. Unprofitable fishermen who wish to leave the industry can sell their quotas to more efficient operators capable of earning a higher return on each tonne of fish caught. In this way the overall profitability of the industry can be improved. ITQs could be suitable for use in some other fisheries, so their success in improving the economic performance of the southern bluefin tuna fishery is likely to influence the future direction of fisheries management in Australia.

A lack of adequate property rights for fishermen over fish stocks has been identified as the major underlying cause of the overexploitation of marine fisheries. By giving fishermen more clearly defined long term property rights in the form of ITQs, incentives for fishermen to conserve the fish stock and to maximise their cost efficiency of harvesting are strengthened. Unprofitable fishermen who wish to leave the industry can sell their quotas to more efficient operators capable of earning a higher return on each tonne of fish caught.

Summary

Individual transferable catch quotas (ITQs) were allocated to fishermen in the Australian southern bluefin tuna fishery in 1984. The profitability of the industry increased substantially as a result. This is despite the total Australian catch being halved between 1984 and 1987 due to a decline in the abundance of southern bluefin tuna. The ITQ management system in the fishery was the first in Australia and was amongst the first in the world. Its introduction marked a radical departure from traditional management regimes based on limiting the number of boats allowed to operate and other controls on fishing inputs. These traditional method were, both in Australia and elsewhere, often ineffective in controlling the growth of fishing effort and in generating sustainable long term benefits. A lack of adequate property rights for fishermen over fish stocks has been identified as the major underlying cause of the overexploitation of marine fisheries. By giving fishermen more clearly defined long term property rights in the form of ITQs, incentives for fishermen to conserve the fish stock and to maximise their cost efficiency of harvesting are strengthened. Unprofitable fishermen who wish to leave the industry can sell their quotas to more efficient operators capable of earning a higher return on each tonne of fish caught. In this way the overall profitability of the industry can be improved. ITQs could be suitable for use in some other fisheries, so their success in improving the economic performance of the southern bluefin tuna fishery is likely to influence the future direction of fisheries management in Australia.

Summary

Individual transferable catch quotas (ITQs) were allocated to fishermen in the Australian southern bluefin tuna fishery in 1984. The profitability of the industry increased substantially as a result. This is despite the total Australian catch being halved between 1984 and 1987 due to a decline in the abundance of southern bluefin tuna. The ITQ management system in the fishery was the first in Australia and was amongst the first in the world. Its introduction marked a radical departure from traditional management regimes based on limiting the number of boats allowed to operate and other controls on fishing inputs. These traditional method were, both in Australia and elsewhere, often ineffective in controlling the growth of fishing effort and in generating sustainable long term benefits. A lack of adequate property rights for fishermen over fish stocks has been identified as the major underlying cause of the overexploitation of marine fisheries. By giving fishermen more clearly defined long term property rights in the form of ITQs, incentives for fishermen to conserve the fish stock and to maximise their cost efficiency of harvesting are strengthened. Unprofitable fishermen who wish to leave the industry can sell their quotas to more efficient operators capable of earning a higher return on each tonne of fish caught.

This is despite the total Australian catch being halved between 1984 and 1987 due to a decline in the abundance of southern bluefin tuna. The ITQ management system in the fishery was the first in Australia and was amongst the first in the world. Its introduction marked a radical departure from traditional management regimes based on limiting the number of boats allowed to operate and other controls on fishing inputs. These traditional method were, both in Australia and elsewhere, often ineffective in controlling the growth of fishing effort and in generating sustainable long term benefits. A lack of adequate property rights for fishermen over fish stocks has been identified as the major underlying cause of the overexploitation of marine fisheries. By giving fishermen more clearly defined long term property rights in the form of ITQs, incentives for fishermen to conserve the fish stock and to maximise their cost efficiency of harvesting are strengthened. Unprofitable fishermen who wish to leave the industry can sell their quotas to more efficient operators capable of earning a higher return on each tonne of fish caught. In this way the overall profitability of the industry can be improved. ITQs could be suitable for use in some other fisheries, so their success in improving the economic performance of the southern bluefin tuna fishery is likely to influence the future direction of fisheries management in Australia.

Unprofitable fishermen who wish to leave the industry can sell their quotas to more efficient operators capable of earning a higher return on each tonne of fish caught. In this way the overall profitability of the industry can be improved. ITQs could be suitable for use in some other fisheries, so their success in improving the economic performance of the southern bluefin tuna fishery is likely to influence the future direction of fisheries management in Australia.

Summary

Individual transferable catch quotas (ITQs) were allocated to fishermen in the Australian southern bluefin tuna fishery in 1984. The profitability of the industry increased substantially as a result. This is despite the total Australian catch being halved between 1984 and 1987 due to a decline in the abundance of southern bluefin tuna. The ITQ management system in the fishery was the first in Australia and was amongst the first in the world. Its introduction marked a radical departure from traditional management regimes based on limiting the number of boats allowed to operate and other controls on fishing inputs. These traditional method were, both in Australia and elsewhere, often ineffective in controlling the growth of fishing effort and in generating sustainable long term benefits.

This is despite the total Australian catch being halved between 1984 and 1987 due to a decline in the abundance of southern bluefin tuna. The ITQ management system in the fishery was the first in Australia and was amongst the first in the world. Its introduction marked a radical departure from traditional management regimes based on limiting the number of boats allowed to operate and other controls on fishing inputs. These traditional method were, both in Australia and elsewhere, often ineffective in controlling the growth of fishing effort and in generating sustainable long term benefits. A lack of adequate property rights for fishermen over fish stocks has been identified as the major underlying cause of the overexploitation of marine fisheries. By giving fishermen more clearly defined long term property rights in the form of ITQs, incentives for fishermen to conserve the fish stock and to maximise their cost efficiency of harvesting are strengthened. Unprofitable fishermen who wish to leave the industry can sell their quotas to more efficient operators capable of earning a higher return on each tonne of fish caught. In this way the overall profitability of the industry can be improved. ITQs could be suitable for use in some other fisheries, so their success in improving the economic performance of the southern bluefin tuna fishery is likely to influence the future direction of fisheries management in Australia.

Unprofitable fishermen who wish to leave the industry can sell their quotas to more efficient operators capable of earning a higher return on each tonne of fish caught. In this way the overall profitability of the industry can be improved. ITQs could be suitable for use in some other fisheries, so their success in improving the economic performance of the southern bluefin tuna fishery is likely to influence the future direction of fisheries management in Australia.

Summary

Individual transferable catch quotas (ITQs) were allocated to fishermen in the Australian southern bluefin tuna fishery in 1984. The profitability of the industry increased substantially as a result. This is despite the total Australian catch being halved between 1984 and 1987 due to a decline in the abundance of southern bluefin tuna. The ITQ management system in the fishery was the first in Australia and was amongst the first in the world. Its introduction marked a radical departure from traditional management regimes based on limiting the number of boats allowed to operate and other controls on fishing inputs. These traditional method were, both in Australia and elsewhere, often ineffective in controlling the growth of fishing effort and in generating sustainable long term benefits.

This is despite the total Australian catch being halved between 1984 and 1987 due to a decline in the abundance of southern bluefin tuna. The ITQ management system in the fishery was the first in Australia and was amongst the first in the world. Its introduction marked a radical departure from traditional management regimes based on limiting the number of boats allowed to operate and other controls on fishing inputs. These traditional method were, both in Australia and elsewhere, often ineffective in controlling the growth of fishing effort and in generating sustainable long term benefits. A lack of adequate property rights for fishermen over fish stocks has been identified as the major underlying cause of the overexploitation of marine fisheries. By giving fishermen more clearly defined long term property rights in the form of ITQs, incentives for fishermen to conserve the fish stock and to maximise their cost efficiency of harvesting are strengthened. Unprofitable fishermen who wish to leave the industry can sell their quotas to more efficient operators capable of earning a higher return on each tonne of fish caught. In this way the overall profitability of the industry can be improved. ITQs could be suitable for use in some other fisheries, so their success in improving the economic performance of the southern bluefin tuna fishery is likely to influence the future direction of fisheries management in Australia.

Unprofitable fishermen who wish to leave the industry can sell their quotas to more efficient operators capable of earning a higher return on each tonne of fish caught. In this way the overall profitability of the industry can be improved. ITQs could be suitable for use in some other fisheries, so their success in improving the economic performance of the southern bluefin tuna fishery is likely to influence the future direction of fisheries management in Australia.

Summary

Individual transferable catch quotas (ITQs) were allocated to fishermen in the Australian southern bluefin tuna fishery in 1984. The profitability of the industry increased substantially as a result. This is despite the total Australian catch being halved between 1984 and 1987 due to a decline in the abundance of southern bluefin tuna. The ITQ management system in the fishery was the first in Australia and was amongst the first in the world. Its introduction marked a radical departure from traditional management regimes based on limiting the number of boats allowed to operate and other controls on fishing inputs. These traditional method were, both in Australia and elsewhere, often ineffective in controlling the growth of fishing effort and in generating sustainable long term benefits.

This is despite the total Australian catch being halved between 1984 and 1987 due to a decline in the abundance of southern bluefin tuna. The ITQ management system in the fishery was the first in Australia and was amongst the first in the world. Its introduction marked a radical departure from traditional management regimes based on limiting the number of boats allowed to operate and other controls on fishing inputs. These traditional method were, both in Australia and elsewhere, often ineffective in controlling the growth of fishing effort and in generating sustainable long term benefits. A lack of adequate property rights for fishermen over fish stocks has been identified as the major underlying cause of the overexploitation of marine fisheries. By giving fishermen more clearly defined long term property rights in the form of ITQs, incentives for fishermen to conserve the fish stock and to maximise their cost efficiency of harvesting are strengthened. Unprofitable fishermen who wish to leave the industry can sell their quotas to more efficient operators capable of earning a higher return on each tonne of fish caught. In this way the overall profitability of the industry can be improved. ITQs could be suitable for use in some other fisheries, so their success in improving the economic performance of the southern bluefin tuna fishery is likely to influence the future direction of fisheries management in Australia.

Unprofitable fishermen who wish to leave the industry can sell their quotas to more efficient operators capable of earning a higher return on each tonne of fish caught. In this way the overall profitability of the industry can be improved. ITQs could be suitable for use in some other fisheries, so their success in improving the economic performance of the southern bluefin tuna fishery is likely to influence the future direction of fisheries management in Australia.

Summary

Individual transferable catch quotas (ITQs) were allocated to fishermen in the Australian southern bluefin tuna fishery in 1984. The profitability of the industry increased substantially as a result. This is despite the total Australian catch being halved between 1984 and 1987 due to a decline in the abundance of southern bluefin tuna. The ITQ management system in the fishery was the first in Australia and was amongst the first in the world. Its introduction marked a radical departure from traditional management regimes based on limiting the number of boats allowed to operate and other controls on fishing inputs. These traditional method were, both in Australia and elsewhere, often ineffective in controlling the growth of fishing effort and in generating sustainable long term benefits.

This is despite the total Australian catch being halved between 1984 and 1987 due to a decline in the abundance of southern bluefin tuna. The ITQ management system in the fishery was the first in Australia and was amongst the first in the world. Its introduction marked a radical departure from traditional management regimes based on limiting the number of boats allowed to operate and other controls on fishing inputs. These traditional method were, both in Australia and elsewhere, often ineffective in controlling the growth of fishing effort and in generating sustainable long term benefits. A lack of adequate property rights for fishermen over fish stocks has been identified as the major underlying cause of the overexploitation of marine fisheries. By giving fishermen more clearly defined long term property rights in the form of ITQs, incentives for fishermen to conserve the fish stock and to maximise their cost efficiency of harvesting are strengthened. Unprofitable fishermen who wish to leave the industry can sell their quotas to more efficient operators capable of earning a higher return on each tonne of fish caught. In this way the overall profitability of the industry can be improved. ITQs could be suitable for use in some other fisheries, so their success in improving the economic performance of the southern bluefin tuna fishery is likely to influence the future direction of fisheries management in Australia.

Unprofitable fishermen who wish to leave the industry can sell their quotas to more efficient operators capable of earning a higher return on each tonne of fish caught. In this way the overall profitability of the industry can be improved. ITQs could be suitable for use in some other fisheries, so their success in improving the economic performance of the southern bluefin tuna fishery is likely to influence the future direction of fisheries management in Australia.

Summary

Individual transferable catch quotas (ITQs) were allocated to fishermen in the Australian southern bluefin tuna fishery in 1984. The profitability of the industry increased substantially as a result. This is despite the total Australian catch being halved between 1984 and 1987 due to a decline in the abundance of southern bluefin tuna. The ITQ management system in the fishery was the first in Australia and was amongst the first in the world. Its introduction marked a radical departure from traditional management regimes based on limiting the number of boats allowed to operate and other controls on fishing inputs. These traditional method were, both in Australia and elsewhere, often ineffective in controlling the growth of fishing effort and in generating sustainable long term benefits.

Seafood CRC: waste transformation methods for value added products for the catering market

Project number: 2014-704
Project Status:
Completed

Need

Up to 60% of food waste (including seafood waste) is potentially avoidable. In the case of seafood specifically, at least 50% of the fish is generally lost re filleting and damaged crustacea such as rock lobster, crabs and prawn sbring low return to the producer. Often there is a business cost incurred in removing seafood prodessing waste.

Reducing and transforming seafood processing waste seems essential to add profitability where possible to the Australian seafood industry.

This project will use mechanical separation, reforming by alginate and extrusion technologies from other food industries, to try and develop a range of value added products from seafood processing waste.

Objectives

1. To successfully launch at least 2 products produced form seafood processing waste on the institutional catering market.

Summary

This report summarises the research undertaken under FRDC 2014/704: Waste Transformation for the Catering Market. The project aimed to develop and launch at least two value-added products on the institutional catering market using seafood processing waste.
Initially a variety of different seafood processing waste products including picked and seconds Blue Swimmer Crabs, Snapper, Atlantic Salmon and various reef fish frames, Patagonian Toothfish frames, Western Rock Lobster legs, headed and gutted shark, low value prawns and headed and gutted Leatherjacket were transported to the Abacus Fisheries facility in Carnarvon. Mechanical separation of seafood protein from these products was optimised with subsequent data generated on recoveries, and compositional and microbiological food safety analyses. These various forms of separated seafood protein were then used for new product development trials.
During the project, a number of new technologies for seafood protein separation, stabilisation and reforming were developed that can be applied generally to seafood processing waste recovery and new product development.

Summary

Results of a previous FIRTA-funded project (86/53) indicated that red spot disease (RSD), a cutaneous ulcerative disease of estuarine fish, is caused by a number of interacting factors. The study showed that lower catchment rainfall is an important determinant of RSD outbreak occurrence. The study also showed that dissolved oxygen concentrations at representative estuarine sites fell to very low levels within 7-10 days of such rain events. Concentrations remained low for a further 8-10 days, as flood waters receded. These findings indicate that rapid and severe changes in one or more water quality parameters, including dissolved oxygen concentrations, pH, salinity and temperature, may be important in initiating RSD outbreaks. Another key finding of the study was that RSD ulcers are a consequence of massive invasion of skin and underlying muscle by morphologically similar, non-septate fungal hyphae. These invasive hyphae cause extensive tissue destruction and provoke a characteristic granulomatous inflammatory response.

There was no evidence that bacteria, cutaneous ectoparasites or viruses were essential in induction of lesions.

The present project was designed to identify water quality parameters important in induction of RSD lesions, and to identify invasive fungi associated with ulcers.

Another key finding of the study was that RSD ulcers are a consequence of massive invasion of skin and underlying muscle by morphologically similar, non-septate fungal hyphae. These invasive hyphae cause extensive tissue destruction and provoke a characteristic granulomatous inflammatory response.

There was no evidence that bacteria, cutaneous ectoparasites or viruses were essential in induction of lesions.

The present project was designed to identify water quality parameters important in induction of RSD lesions, and to identify invasive fungi associated with ulcers.

Summary

Results of a previous FIRTA-funded project (86/53) indicated that red spot disease (RSD), a cutaneous ulcerative disease of estuarine fish, is caused by a number of interacting factors. The study showed that lower catchment rainfall is an important determinant of RSD outbreak occurrence. The study also showed that dissolved oxygen concentrations at representative estuarine sites fell to very low levels within 7-10 days of such rain events. Concentrations remained low for a further 8-10 days, as flood waters receded. These findings indicate that rapid and severe changes in one or more water quality parameters, including dissolved oxygen concentrations, pH, salinity and temperature, may be important in initiating RSD outbreaks.
