Need

There is a need to meet the CRC’s desired $240 million gain in seafood value through innovative technologies as scheduled in the CRC program 1. This proposal will contribute up to 47% of this CRC goal, as explained in the “background” section.

This application also meets the need to respond to the FRDC’s challenge 3 (response to demand, profitability) and FRDC priority “develop innovative processes for value-adding through
development” (genetic improvement will return greater profit per kg, or increase kgs for same infrastructure). Should the “Seafarm” transformational model be adopted by others, this will directly support the achievement of FRDC’s key performance indicators “at least two companies accessing new markets”, and “at least two entities utilizing improved stock from selective breeding”.

This application supports the stated and written need from the APFA, as a major stakeholder, to achieve a method to apply its R&D levy for the whole of the industry, for both P. monodon and F. merguiensis. The application makes the case that as a transformational model for profitability through innovative technologies this project delivers industry wide outcomes

Objectives

1. Understand if past and existing breeding practices led to significant inbreeding (more than 2% per generation) and, if substantial inbreeding has occurred and will continue to occur, develop options to track family pedigrees and so more effectively limit inbreeding
2. Estimate genetic heritabilities and correlations for commercially important traits. This information will be available for companies to develop efficient breeding programs
3. Determine if functional markers for a range of commercial traits are commercially feasible. If so, these makers will be available for companies to integrate into their breeding programs through a selection index

Summary

Seafarm, at Cardwell, for most of the last 20 years, has been Australia’s largest prawn farm and the major producer of Banana Prawns. This producer wanted to understand and resolve the suspected inbreeding/ loss of diversity issues, and if necessary, redesign their breeding program to ensure it would be sustainable in the long term. This project attempted a “forensic” examination of a prawn selection program with the intention that the information would help make the program more sustainable and contribute foundation knowledge of what likely happens in such mass selection programs conducted by other companies on organisms with very high fecundities. It was also tested whether hepatopacreatic parvovirus (HPV) was under genetic control.

This project was able to provide genetic management information that promoted increased productivity at Seafarm, helping to revise their genetic breeding program to mitigate inbreeding and restore allelic diversity. The revised program has halted further inbreeding; increased the diversity in the crossed lined; lifted the growth of the outcrossed lines vs the inbred lines; and accelerated the rate of selection response.

Seafarm, at Cardwell, for most of the last 20 years, has been Australia’s largest prawn farm and the major producer of Banana Prawns. This producer wanted to understand and resolve the suspected inbreeding/ loss of diversity issues, and if necessary, redesign their breeding program to ensure it would be sustainable in the long term. This project attempted a “forensic” examination of a prawn selection program with the intention that the information would help make the program more sustainable and contribute foundation knowledge of what likely happens in such mass selection programs conducted by other companies on organisms with very high fecundities. It was also tested whether hepatopacreatic parvovirus (HPV) was under genetic control.

This project was able to provide genetic management information that promoted increased productivity at Seafarm, helping to revise their genetic breeding program to mitigate inbreeding and restore allelic diversity. The revised program has halted further inbreeding; increased the diversity in the crossed lined; lifted the growth of the outcrossed lines vs the inbred lines; and accelerated the rate of selection response.

This producer wanted to understand and resolve the suspected inbreeding/ loss of diversity issues, and if necessary, redesign their breeding program to ensure it would be sustainable in the long term. This project attempted a “forensic” examination of a prawn selection program with the intention that the information would help make the program more sustainable and contribute foundation knowledge of what likely happens in such mass selection programs conducted by other companies on organisms with very high fecundities. It was also tested whether hepatopacreatic parvovirus (HPV) was under genetic control.

This project was able to provide genetic management information that promoted increased productivity at Seafarm, helping to revise their genetic breeding program to mitigate inbreeding and restore allelic diversity. The revised program has halted further inbreeding; increased the diversity in the crossed lined; lifted the growth of the outcrossed lines vs the inbred lines; and accelerated the rate of selection response.

This producer wanted to understand and resolve the suspected inbreeding/ loss of diversity issues, and if necessary, redesign their breeding program to ensure it would be sustainable in the long term. This project attempted a “forensic” examination of a prawn selection program with the intention that the information would help make the program more sustainable and contribute foundation knowledge of what likely happens in such mass selection programs conducted by other companies on organisms with very high fecundities. It was also tested whether hepatopacreatic parvovirus (HPV) was under genetic control.

This project was able to provide genetic management information that promoted increased productivity at Seafarm, helping to revise their genetic breeding program to mitigate inbreeding and restore allelic diversity. The revised program has halted further inbreeding; increased the diversity in the crossed lined; lifted the growth of the outcrossed lines vs the inbred lines; and accelerated the rate of selection response.

This producer wanted to understand and resolve the suspected inbreeding/ loss of diversity issues, and if necessary, redesign their breeding program to ensure it would be sustainable in the long term. This project attempted a “forensic” examination of a prawn selection program with the intention that the information would help make the program more sustainable and contribute foundation knowledge of what likely happens in such mass selection programs conducted by other companies on organisms with very high fecundities. It was also tested whether hepatopacreatic parvovirus (HPV) was under genetic control.

This project was able to provide genetic management information that promoted increased productivity at Seafarm, helping to revise their genetic breeding program to mitigate inbreeding and restore allelic diversity. The revised program has halted further inbreeding; increased the diversity in the crossed lined; lifted the growth of the outcrossed lines vs the inbred lines; and accelerated the rate of selection response.

This producer wanted to understand and resolve the suspected inbreeding/ loss of diversity issues, and if necessary, redesign their breeding program to ensure it would be sustainable in the long term. This project attempted a “forensic” examination of a prawn selection program with the intention that the information would help make the program more sustainable and contribute foundation knowledge of what likely happens in such mass selection programs conducted by other companies on organisms with very high fecundities. It was also tested whether hepatopacreatic parvovirus (HPV) was under genetic control.

This project was able to provide genetic management information that promoted increased productivity at Seafarm, helping to revise their genetic breeding program to mitigate inbreeding and restore allelic diversity. The revised program has halted further inbreeding; increased the diversity in the crossed lined; lifted the growth of the outcrossed lines vs the inbred lines; and accelerated the rate of selection response.

This producer wanted to understand and resolve the suspected inbreeding/ loss of diversity issues, and if necessary, redesign their breeding program to ensure it would be sustainable in the long term. This project attempted a “forensic” examination of a prawn selection program with the intention that the information would help make the program more sustainable and contribute foundation knowledge of what likely happens in such mass selection programs conducted by other companies on organisms with very high fecundities. It was also tested whether hepatopacreatic parvovirus (HPV) was under genetic control.

This project was able to provide genetic management information that promoted increased productivity at Seafarm, helping to revise their genetic breeding program to mitigate inbreeding and restore allelic diversity. The revised program has halted further inbreeding; increased the diversity in the crossed lined; lifted the growth of the outcrossed lines vs the inbred lines; and accelerated the rate of selection response.

This producer wanted to understand and resolve the suspected inbreeding/ loss of diversity issues, and if necessary, redesign their breeding program to ensure it would be sustainable in the long term. This project attempted a “forensic” examination of a prawn selection program with the intention that the information would help make the program more sustainable and contribute foundation knowledge of what likely happens in such mass selection programs conducted by other companies on organisms with very high fecundities. It was also tested whether hepatopacreatic parvovirus (HPV) was under genetic control.

This project was able to provide genetic management information that promoted increased productivity at Seafarm, helping to revise their genetic breeding program to mitigate inbreeding and restore allelic diversity. The revised program has halted further inbreeding; increased the diversity in the crossed lined; lifted the growth of the outcrossed lines vs the inbred lines; and accelerated the rate of selection response.

This producer wanted to understand and resolve the suspected inbreeding/ loss of diversity issues, and if necessary, redesign their breeding program to ensure it would be sustainable in the long term. This project attempted a “forensic” examination of a prawn selection program with the intention that the information would help make the program more sustainable and contribute foundation knowledge of what likely happens in such mass selection programs conducted by other companies on organisms with very high fecundities. It was also tested whether hepatopacreatic parvovirus (HPV) was under genetic control.

This project was able to provide genetic management information that promoted increased productivity at Seafarm, helping to revise their genetic breeding program to mitigate inbreeding and restore allelic diversity. The revised program has halted further inbreeding; increased the diversity in the crossed lined; lifted the growth of the outcrossed lines vs the inbred lines; and accelerated the rate of selection response.

This producer wanted to understand and resolve the suspected inbreeding/ loss of diversity issues, and if necessary, redesign their breeding program to ensure it would be sustainable in the long term. This project attempted a “forensic” examination of a prawn selection program with the intention that the information would help make the program more sustainable and contribute foundation knowledge of what likely happens in such mass selection programs conducted by other companies on organisms with very high fecundities. It was also tested whether hepatopacreatic parvovirus (HPV) was under genetic control.

This project was able to provide genetic management information that promoted increased productivity at Seafarm, helping to revise their genetic breeding program to mitigate inbreeding and restore allelic diversity. The revised program has halted further inbreeding; increased the diversity in the crossed lined; lifted the growth of the outcrossed lines vs the inbred lines; and accelerated the rate of selection response.

Fishing with trawl gear expends more fuel per kg of fish landed compared to passive methods such as longlining and trap fishing. In all cases however, rising fuel prices impinge on the profitability of the operations, and ultimately put their viability in jeopardy; this has reach a critical situation for many trawl operators in Australia.
This project to implement high strength netting and demonstrate the positive outcomes for the prawn trawling industry has the intention of reducing the fuel used by fishing enterprises and shifting the industry towards a more economically viable and environmentally sustainable position.
Specifically, research is required to document and define the difficulties/problems associated with using high strength netting in prawn trawling applications and develop solutions for its successful implementation; followed by quantification of the nett benefit achieved.
This contributes to the R&D plans and strategies of all advisory bodies to the FRDC, since they contain high priority goals to achieve FRDC’s planned outcome for Industry Development, that: "The commercial sector of the Australian fishing industry is profitable, internationally competitive and socially resilient".

Objectives

1. For commercial netting of 50mm nominal mesh size, measure and compare the dimensional, mechanical and hydrodynamic characteristics of 1.65mm twisted PE (24 ply), 1.0mm twisted Spectra and 1.1mm braided Dynema.
2. Compare the engineering and catching performance of three dual-rig prawn trawling systems
each configured to be compatible (“optimal”) respectively to the three netting types under investigation.

Need

Even when using a 4-hexylresorcinol dip the protection provided is not uniform (Guandalini et al., 1998). The residue from a once off dip drops rapidly over a number of days storage. The authors found that towards the end of organoleptic acceptability 20-30% of prawns were unaffected by blackspot. This researcher noted similar uneven blackspot development during storage (Slattery et al., 1995). This outcome is obviously due to uneven exposure and retention of the limited amount of 4-hexylresorcinol that a quick dip in a solution of the chemical can supply.

There is limited information on the effect of longer term treatment with 4-hexylresorcinol but only at the same concentration as the short dip (Iyengar et al., 1991 and Slattery et al., 1995). Providing industry with this type of information will lead to more adoption of a safer chemical and less chemical treatment of prawns.

Unlike Australia, many importing countries have defined residue limits which the product has to comply with. It is unknown what residues are likely from any long term exposure. The only information available is from a one hour dip of live prawns in the standard concentration which resulted in very high residues.

A range of methods of using Everfresh that will provide good protection from blackspot, yet result in low residues, is needed by the prawn industry. This research will assist the APFA Tactical R&D Plan by increasing profitability through reduced usage and wastage of expensive chemicals. The QSMA have been trying to convince the wild capture prawn industry to adopt the use of Everfresh for some time. This work would meet ASIC concerns for quality and safety of seafood. This project also complies with the SSA Plans for Seafood Quality and Safety in Segment 3.

Objectives

1. Identify alternate methods for treatment of aquaculture prawns with Everfresh to the standard 2 minute dip.
2. Identify alternate methods for treatment of wild caught prawns with Everfresh to the standard 2 minute dip.
3. Identify treatments that will result in residues that will comply with overseas requirements.

Disseminating existing bycatch reduction and fuel efficiency technologies throughout Australia's prawn fisheries

Prawn trawling is among the world's least selective fishing methods, the unintended consequence being large quantities of bycatch. It is also a method that can disturb benthic habitats and use large quantities of fuel—a significant running cost for many fisheries. Issues of bycatch and fuel...
