Summary

Since colonisation, Australia has been a country that relies heavily upon the export of its agricultural produce to contribute to the wealth and prosperity of the nation. However, in recent times, the export focus and capability of the agricultural industry has decreased. Whilst the overall importance of exporting is recognised in the academic literature, the determinants of export propensity in countries outside the United States and the European Union have received little attention. This gap in the literature is despite the reality that improving the export propensity of Australian agricultural firms has become an area of increasing importance to government bodies and private industry alike. More specifically, this need for improvement and growth is especially the case for the Australian seafood industry.

A thorough review of the extant literature identified several factors that have a direct association with a firm's export propensity. This research proposed that a firm's human resources, relationship capabilities and information capabilities impact on their export propensity.
The research design adopted for this study was comprised of two stages. The first stage was a qualitative, exploratory stage consisting of four in-depth interviews with seafood industry experts. The second stage consisted of case study interviews where data was collected through semi-structured, in-depth interviews with senior management from two prawn farms and two prawn fishers.

The findings indicate that a firm's internal resources and capabilities do impact on export propensity, particularly the commitment and experience of managerial staff, information capabilities and relationship capability to a lesser degree, play an important role in creating export propensity.

More specifically, this need for improvement and growth is especially the case for the Australian seafood industry.

A thorough review of the extant literature identified several factors that have a direct association with a firm's export propensity. This research proposed that a firm's human resources, relationship capabilities and information capabilities impact on their export propensity.
The research design adopted for this study was comprised of two stages. The first stage was a qualitative, exploratory stage consisting of four in-depth interviews with seafood industry experts. The second stage consisted of case study interviews where data was collected through semi-structured, in-depth interviews with senior management from two prawn farms and two prawn fishers.

The findings indicate that a firm's internal resources and capabilities do impact on export propensity, particularly the commitment and experience of managerial staff, information capabilities and relationship capability to a lesser degree, play an important role in creating export propensity.

Whilst the overall importance of exporting is recognised in the academic literature, the determinants of export propensity in countries outside the United States and the European Union have received little attention. This gap in the literature is despite the reality that improving the export propensity of Australian agricultural firms has become an area of increasing importance to government bodies and private industry alike. More specifically, this need for improvement and growth is especially the case for the Australian seafood industry.

A thorough review of the extant literature identified several factors that have a direct association with a firm's export propensity. This research proposed that a firm's human resources, relationship capabilities and information capabilities impact on their export propensity.
The research design adopted for this study was comprised of two stages. The first stage was a qualitative, exploratory stage consisting of four in-depth interviews with seafood industry experts. The second stage consisted of case study interviews where data was collected through semi-structured, in-depth interviews with senior management from two prawn farms and two prawn fishers.

The findings indicate that a firm's internal resources and capabilities do impact on export propensity, particularly the commitment and experience of managerial staff, information capabilities and relationship capability to a lesser degree, play an important role in creating export propensity.

Since colonisation, Australia has been a country that relies heavily upon the export of its agricultural produce to contribute to the wealth and prosperity of the nation. However, in recent times, the export focus and capability of the agricultural industry has decreased. Whilst the overall importance of exporting is recognised in the academic literature, the determinants of export propensity in countries outside the United States and the European Union have received little attention. This gap in the literature is despite the reality that improving the export propensity of Australian agricultural firms has become an area of increasing importance to government bodies and private industry alike. More specifically, this need for improvement and growth is especially the case for the Australian seafood industry.

A thorough review of the extant literature identified several factors that have a direct association with a firm's export propensity. This research proposed that a firm's human resources, relationship capabilities and information capabilities impact on their export propensity.
The research design adopted for this study was comprised of two stages. The first stage was a qualitative, exploratory stage consisting of four in-depth interviews with seafood industry experts. The second stage consisted of case study interviews where data was collected through semi-structured, in-depth interviews with senior management from two prawn farms and two prawn fishers.

The findings indicate that a firm's internal resources and capabilities do impact on export propensity, particularly the commitment and experience of managerial staff, information capabilities and relationship capability to a lesser degree, play an important role in creating export propensity.

Summary

Since colonisation, Australia has been a country that relies heavily upon the export of its agricultural produce to contribute to the wealth and prosperity of the nation. However, in recent times, the export focus and capability of the agricultural industry has decreased. Whilst the overall importance of exporting is recognised in the academic literature, the determinants of export propensity in countries outside the United States and the European Union have received little attention. This gap in the literature is despite the reality that improving the export propensity of Australian agricultural firms has become an area of increasing importance to government bodies and private industry alike. More specifically, this need for improvement and growth is especially the case for the Australian seafood industry.

A thorough review of the extant literature identified several factors that have a direct association with a firm's export propensity. This research proposed that a firm's human resources, relationship capabilities and information capabilities impact on their export propensity.
The research design adopted for this study was comprised of two stages. The first stage was a qualitative, exploratory stage consisting of four in-depth interviews with seafood industry experts. The second stage consisted of case study interviews where data was collected through semi-structured, in-depth interviews with senior management from two prawn farms and two prawn fishers.

The findings indicate that a firm's internal resources and capabilities do impact on export propensity, particularly the commitment and experience of managerial staff, information capabilities and relationship capability to a lesser degree, play an important role in creating export propensity.

Summary

Since colonisation, Australia has been a country that relies heavily upon the export of its agricultural produce to contribute to the wealth and prosperity of the nation. However, in recent times, the export focus and capability of the agricultural industry has decreased. Whilst the overall importance of exporting is recognised in the academic literature, the determinants of export propensity in countries outside the United States and the European Union have received little attention. This gap in the literature is despite the reality that improving the export propensity of Australian agricultural firms has become an area of increasing importance to government bodies and private industry alike. More specifically, this need for improvement and growth is especially the case for the Australian seafood industry.

A thorough review of the extant literature identified several factors that have a direct association with a firm's export propensity. This research proposed that a firm's human resources, relationship capabilities and information capabilities impact on their export propensity.
The research design adopted for this study was comprised of two stages. The first stage was a qualitative, exploratory stage consisting of four in-depth interviews with seafood industry experts.

The research design adopted for this study was comprised of two stages. The first stage was a qualitative, exploratory stage consisting of four in-depth interviews with seafood industry experts. The second stage consisted of case study interviews where data was collected through semi-structured, in-depth interviews with senior management from two prawn farms and two prawn fishers.

The findings indicate that a firm's internal resources and capabilities do impact on export propensity, particularly the commitment and experience of managerial staff, information capabilities and relationship capability to a lesser degree, play an important role in creating export propensity.

Summary

Since colonisation, Australia has been a country that relies heavily upon the export of its agricultural produce to contribute to the wealth and prosperity of the nation. However, in recent times, the export focus and capability of the agricultural industry has decreased. Whilst the overall importance of exporting is recognised in the academic literature, the determinants of export propensity in countries outside the United States and the European Union have received little attention. This gap in the literature is despite the reality that improving the export propensity of Australian agricultural firms has become an area of increasing importance to government bodies and private industry alike. More specifically, this need for improvement and growth is especially the case for the Australian seafood industry.

More specifically, this need for improvement and growth is especially the case for the Australian seafood industry.

A thorough review of the extant literature identified several factors that have a direct association with a firm's export propensity. This research proposed that a firm's human resources, relationship capabilities and information capabilities impact on their export propensity.
The research design adopted for this study was comprised of two stages. The first stage was a qualitative, exploratory stage consisting of four in-depth interviews with seafood industry experts. The second stage consisted of case study interviews where data was collected through semi-structured, in-depth interviews with senior management from two prawn farms and two prawn fishers.

The findings indicate that a firm's internal resources and capabilities do impact on export propensity, particularly the commitment and experience of managerial staff, information capabilities and relationship capability to a lesser degree, play an important role in creating export propensity.

Whilst the overall importance of exporting is recognised in the academic literature, the determinants of export propensity in countries outside the United States and the European Union have received little attention. This gap in the literature is despite the reality that improving the export propensity of Australian agricultural firms has become an area of increasing importance to government bodies and private industry alike. More specifically, this need for improvement and growth is especially the case for the Australian seafood industry.

A thorough review of the extant literature identified several factors that have a direct association with a firm's export propensity. This research proposed that a firm's human resources, relationship capabilities and information capabilities impact on their export propensity.
The research design adopted for this study was comprised of two stages. The first stage was a qualitative, exploratory stage consisting of four in-depth interviews with seafood industry experts. The second stage consisted of case study interviews where data was collected through semi-structured, in-depth interviews with senior management from two prawn farms and two prawn fishers.

The findings indicate that a firm's internal resources and capabilities do impact on export propensity, particularly the commitment and experience of managerial staff, information capabilities and relationship capability to a lesser degree, play an important role in creating export propensity.

Since colonisation, Australia has been a country that relies heavily upon the export of its agricultural produce to contribute to the wealth and prosperity of the nation. However, in recent times, the export focus and capability of the agricultural industry has decreased. Whilst the overall importance of exporting is recognised in the academic literature, the determinants of export propensity in countries outside the United States and the European Union have received little attention. This gap in the literature is despite the reality that improving the export propensity of Australian agricultural firms has become an area of increasing importance to government bodies and private industry alike. More specifically, this need for improvement and growth is especially the case for the Australian seafood industry.

A thorough review of the extant literature identified several factors that have a direct association with a firm's export propensity. This research proposed that a firm's human resources, relationship capabilities and information capabilities impact on their export propensity.
The research design adopted for this study was comprised of two stages. The first stage was a qualitative, exploratory stage consisting of four in-depth interviews with seafood industry experts. The second stage consisted of case study interviews where data was collected through semi-structured, in-depth interviews with senior management from two prawn farms and two prawn fishers.

The findings indicate that a firm's internal resources and capabilities do impact on export propensity, particularly the commitment and experience of managerial staff, information capabilities and relationship capability to a lesser degree, play an important role in creating export propensity.

Summary

Since colonisation, Australia has been a country that relies heavily upon the export of its agricultural produce to contribute to the wealth and prosperity of the nation. However, in recent times, the export focus and capability of the agricultural industry has decreased. Whilst the overall importance of exporting is recognised in the academic literature, the determinants of export propensity in countries outside the United States and the European Union have received little attention. This gap in the literature is despite the reality that improving the export propensity of Australian agricultural firms has become an area of increasing importance to government bodies and private industry alike. More specifically, this need for improvement and growth is especially the case for the Australian seafood industry.

A thorough review of the extant literature identified several factors that have a direct association with a firm's export propensity. This research proposed that a firm's human resources, relationship capabilities and information capabilities impact on their export propensity.
The research design adopted for this study was comprised of two stages. The first stage was a qualitative, exploratory stage consisting of four in-depth interviews with seafood industry experts. The second stage consisted of case study interviews where data was collected through semi-structured, in-depth interviews with senior management from two prawn farms and two prawn fishers.

The findings indicate that a firm's internal resources and capabilities do impact on export propensity, particularly the commitment and experience of managerial staff, information capabilities and relationship capability to a lesser degree, play an important role in creating export propensity.

Summary

Since colonisation, Australia has been a country that relies heavily upon the export of its agricultural produce to contribute to the wealth and prosperity of the nation. However, in recent times, the export focus and capability of the agricultural industry has decreased. Whilst the overall importance of exporting is recognised in the academic literature, the determinants of export propensity in countries outside the United States and the European Union have received little attention. This gap in the literature is despite the reality that improving the export propensity of Australian agricultural firms has become an area of increasing importance to government bodies and private industry alike. More specifically, this need for improvement and growth is especially the case for the Australian seafood industry.

A thorough review of the extant literature identified several factors that have a direct association with a firm's export propensity. This research proposed that a firm's human resources, relationship capabilities and information capabilities impact on their export propensity.
The research design adopted for this study was comprised of two stages. The first stage was a qualitative, exploratory stage consisting of four in-depth interviews with seafood industry experts.

The research design adopted for this study was comprised of two stages. The first stage was a qualitative, exploratory stage consisting of four in-depth interviews with seafood industry experts. The second stage consisted of case study interviews where data was collected through semi-structured, in-depth interviews with senior management from two prawn farms and two prawn fishers.

The findings indicate that a firm's internal resources and capabilities do impact on export propensity, particularly the commitment and experience of managerial staff, information capabilities and relationship capability to a lesser degree, play an important role in creating export propensity.

Summary

Since colonisation, Australia has been a country that relies heavily upon the export of its agricultural produce to contribute to the wealth and prosperity of the nation. However, in recent times, the export focus and capability of the agricultural industry has decreased. Whilst the overall importance of exporting is recognised in the academic literature, the determinants of export propensity in countries outside the United States and the European Union have received little attention. This gap in the literature is despite the reality that improving the export propensity of Australian agricultural firms has become an area of increasing importance to government bodies and private industry alike. More specifically, this need for improvement and growth is especially the case for the Australian seafood industry.

More specifically, this need for improvement and growth is especially the case for the Australian seafood industry.

A thorough review of the extant literature identified several factors that have a direct association with a firm's export propensity. This research proposed that a firm's human resources, relationship capabilities and information capabilities impact on their export propensity.
The research design adopted for this study was comprised of two stages. The first stage was a qualitative, exploratory stage consisting of four in-depth interviews with seafood industry experts. The second stage consisted of case study interviews where data was collected through semi-structured, in-depth interviews with senior management from two prawn farms and two prawn fishers.

The findings indicate that a firm's internal resources and capabilities do impact on export propensity, particularly the commitment and experience of managerial staff, information capabilities and relationship capability to a lesser degree, play an important role in creating export propensity.

Summary

Fish flesh contains high levels of omega-3 long chain polyunsaturated fatty acids (n-3 LCPUFA) such as eicosapentaenoic (EPA) and docosahexaenoic acid (DHA) are beneficial for human health to help brain and neural development, decrease the risk of cardiovascular disease and help various other aspects of human lives. EPA and DHA can be synthesised via the LCPUFA synthesis pathway in fish from α-linolenic acid (ALA) which is abundant is some plant oils which are totally devoid of n-3 LCPUFA. Captured fish are currently used as a source of fish oil to feed fish in aquaculture, but capture fisheries are currently at their limit and using captured fish stocks as aquaculture feed is unsustainable and therefore alternative lipid sources to replace fish oil are required to allow the aquaculture industry to continue growing.

This research investigated dietary fish oil replacement with plant or terrestrial animal oils and its impact on the seafood product quality of Yellowtail Kingfish (Seriola lalandi), an important aquaculture species in South Australia. It investigated how this replacement affected the expression of the fatty acid synthesis genes ∆6 fatty acyl desaturase (∆6 fads) and fatty acyl elongase (elovl), and the antioxidant genes peroxiredoxin 1 and 4 (Prx1 and 4) and glutathione peroxidase 1 and 4 (GPx1 and 4).
It was found that fish oil substitution with canola oil and poultry oil did not significantly change the expression of the fads or elovl genes. The antioxidant genes also showed no significant changes in gene expression except for GPx1 which showed an increased expression in fish fed the canola oil-based diet compared to fish fed the fish oil-based diet. Based on these results, and the results of the hepatosomatic indices, it is proposed that GPx1 expression may be up-regulated in fish fed the canola oil-based diet due to increased immune system activity as a result of the relatively high concentration of omega-6 fatty acids in their flesh.

This research investigated dietary fish oil replacement with plant or terrestrial animal oils and its impact on the seafood product quality of Yellowtail Kingfish (Seriola lalandi), an important aquaculture species in South Australia. It investigated how this replacement affected the expression of the fatty acid synthesis genes ∆6 fatty acyl desaturase (∆6 fads) and fatty acyl elongase (elovl), and the antioxidant genes peroxiredoxin 1 and 4 (Prx1 and 4) and glutathione peroxidase 1 and 4 (GPx1 and 4).
It was found that fish oil substitution with canola oil and poultry oil did not significantly change the expression of the fads or elovl genes. The antioxidant genes also showed no significant changes in gene expression except for GPx1 which showed an increased expression in fish fed the canola oil-based diet compared to fish fed the fish oil-based diet. Based on these results, and the results of the hepatosomatic indices, it is proposed that GPx1 expression may be up-regulated in fish fed the canola oil-based diet due to increased immune system activity as a result of the relatively high concentration of omega-6 fatty acids in their flesh.

Summary

In this study the suitability of canola oil (CO) and poultry fat (PO) as alternatives to fish oil (FO) was assessed. Furthermore, a real-time RT-qPCR assay to detect hepatic insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-1 (IGFBP-1) was developed. Four isoproteic (450 g kg-1), isolipidic (250 g kg-1) dry extruded diets were formulated to contain PO or CO at 50 or 100% inclusion, as a substitute for FO. Yellowtail Kingfish growth and growth factor gene expression was compared with fish fed a diet containing 100% FO.

Two experiments were conducted separately at optimal (22 oC; 33 d) and sub-optimal (18 oC; 34 d) temperatures with mean initial fish weights of 95.6 ± 0.1 g and 101 ± 0.1 g respectively. At 22 oC Yellowtail Kingfish fed the 50% PO diet grew significantly larger (281.2 ± 1.2 g) than individuals fed the 100% FO diet (266.9 ± 5.9 g). Inclusion of CO at 50% produced equivalent weight gain to the 100% FO diet, however, 100% inclusion of CO produced poor performance in both experiments. Trends in gene expression reflected the response in weight gain to alternative lipids. A positive relationship between hepatic IGF-I mRNA levels and weight gain and also hepatic IGFBP-1 mRNA and weight gain was found. A positive correlation between hepatic IGF-I and IGFBP-1 mRNA levels was also found. Irrespective of diet, fish grew larger at 22 oC than at 18 oC. The findings of this research indicate that improved diet formulations for Yellowtail Kingfish may be achieved through the inclusion of alternative lipid sources and that IGF-I mRNA may be used as a rapid indicator of growth in this species.

Summary

In this study the suitability of canola oil (CO) and poultry fat (PO) as alternatives to fish oil (FO) was assessed. Furthermore, a real-time RT-qPCR assay to detect hepatic insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-1 (IGFBP-1) was developed. Four isoproteic (450 g kg-1), isolipidic (250 g kg-1) dry extruded diets were formulated to contain PO or CO at 50 or 100% inclusion, as a substitute for FO. Yellowtail Kingfish growth and growth factor gene expression was compared with fish fed a diet containing 100% FO.

Two experiments were conducted separately at optimal (22 oC; 33 d) and sub-optimal (18 oC; 34 d) temperatures with mean initial fish weights of 95.6 ± 0.1 g and 101 ± 0.1 g respectively. At 22 oC Yellowtail Kingfish fed the 50% PO diet grew significantly larger (281.2 ± 1.2 g) than individuals fed the 100% FO diet (266.9 ± 5.9 g). Inclusion of CO at 50% produced equivalent weight gain to the 100% FO diet, however, 100% inclusion of CO produced poor performance in both experiments. Trends in gene expression reflected the response in weight gain to alternative lipids. A positive relationship between hepatic IGF-I mRNA levels and weight gain and also hepatic IGFBP-1 mRNA and weight gain was found. A positive correlation between hepatic IGF-I and IGFBP-1 mRNA levels was also found. Irrespective of diet, fish grew larger at 22 oC than at 18 oC. The findings of this research indicate that improved diet formulations for Yellowtail Kingfish may be achieved through the inclusion of alternative lipid sources and that IGF-I mRNA may be used as a rapid indicator of growth in this species.

Summary

In this study the suitability of canola oil (CO) and poultry fat (PO) as alternatives to fish oil (FO) was assessed. Furthermore, a real-time RT-qPCR assay to detect hepatic insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-1 (IGFBP-1) was developed. Four isoproteic (450 g kg-1), isolipidic (250 g kg-1) dry extruded diets were formulated to contain PO or CO at 50 or 100% inclusion, as a substitute for FO. Yellowtail Kingfish growth and growth factor gene expression was compared with fish fed a diet containing 100% FO.

Two experiments were conducted separately at optimal (22 oC; 33 d) and sub-optimal (18 oC; 34 d) temperatures with mean initial fish weights of 95.6 ± 0.1 g and 101 ± 0.1 g respectively. At 22 oC Yellowtail Kingfish fed the 50% PO diet grew significantly larger (281.2 ± 1.2 g) than individuals fed the 100% FO diet (266.9 ± 5.9 g). Inclusion of CO at 50% produced equivalent weight gain to the 100% FO diet, however, 100% inclusion of CO produced poor performance in both experiments. Trends in gene expression reflected the response in weight gain to alternative lipids. A positive relationship between hepatic IGF-I mRNA levels and weight gain and also hepatic IGFBP-1 mRNA and weight gain was found. A positive correlation between hepatic IGF-I and IGFBP-1 mRNA levels was also found. Irrespective of diet, fish grew larger at 22 oC than at 18 oC. The findings of this research indicate that improved diet formulations for Yellowtail Kingfish may be achieved through the inclusion of alternative lipid sources and that IGF-I mRNA may be used as a rapid indicator of growth in this species.

Summary

In this study the suitability of canola oil (CO) and poultry fat (PO) as alternatives to fish oil (FO) was assessed. Furthermore, a real-time RT-qPCR assay to detect hepatic insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-1 (IGFBP-1) was developed. Four isoproteic (450 g kg-1), isolipidic (250 g kg-1) dry extruded diets were formulated to contain PO or CO at 50 or 100% inclusion, as a substitute for FO. Yellowtail Kingfish growth and growth factor gene expression was compared with fish fed a diet containing 100% FO.

Two experiments were conducted separately at optimal (22 oC; 33 d) and sub-optimal (18 oC; 34 d) temperatures with mean initial fish weights of 95.6 ± 0.1 g and 101 ± 0.1 g respectively. At 22 oC Yellowtail Kingfish fed the 50% PO diet grew significantly larger (281.2 ± 1.2 g) than individuals fed the 100% FO diet (266.9 ± 5.9 g). Inclusion of CO at 50% produced equivalent weight gain to the 100% FO diet, however, 100% inclusion of CO produced poor performance in both experiments. Trends in gene expression reflected the response in weight gain to alternative lipids. A positive relationship between hepatic IGF-I mRNA levels and weight gain and also hepatic IGFBP-1 mRNA and weight gain was found. A positive correlation between hepatic IGF-I and IGFBP-1 mRNA levels was also found. Irrespective of diet, fish grew larger at 22 oC than at 18 oC. The findings of this research indicate that improved diet formulations for Yellowtail Kingfish may be achieved through the inclusion of alternative lipid sources and that IGF-I mRNA may be used as a rapid indicator of growth in this species.

Summary

In this study the suitability of canola oil (CO) and poultry fat (PO) as alternatives to fish oil (FO) was assessed. Furthermore, a real-time RT-qPCR assay to detect hepatic insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-1 (IGFBP-1) was developed. Four isoproteic (450 g kg-1), isolipidic (250 g kg-1) dry extruded diets were formulated to contain PO or CO at 50 or 100% inclusion, as a substitute for FO. Yellowtail Kingfish growth and growth factor gene expression was compared with fish fed a diet containing 100% FO.

Two experiments were conducted separately at optimal (22 oC; 33 d) and sub-optimal (18 oC; 34 d) temperatures with mean initial fish weights of 95.6 ± 0.1 g and 101 ± 0.1 g respectively. At 22 oC Yellowtail Kingfish fed the 50% PO diet grew significantly larger (281.2 ± 1.2 g) than individuals fed the 100% FO diet (266.9 ± 5.9 g). Inclusion of CO at 50% produced equivalent weight gain to the 100% FO diet, however, 100% inclusion of CO produced poor performance in both experiments. Trends in gene expression reflected the response in weight gain to alternative lipids. A positive relationship between hepatic IGF-I mRNA levels and weight gain and also hepatic IGFBP-1 mRNA and weight gain was found. A positive correlation between hepatic IGF-I and IGFBP-1 mRNA levels was also found. Irrespective of diet, fish grew larger at 22 oC than at 18 oC. The findings of this research indicate that improved diet formulations for Yellowtail Kingfish may be achieved through the inclusion of alternative lipid sources and that IGF-I mRNA may be used as a rapid indicator of growth in this species.

Summary

In this study the suitability of canola oil (CO) and poultry fat (PO) as alternatives to fish oil (FO) was assessed. Furthermore, a real-time RT-qPCR assay to detect hepatic insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-1 (IGFBP-1) was developed. Four isoproteic (450 g kg-1), isolipidic (250 g kg-1) dry extruded diets were formulated to contain PO or CO at 50 or 100% inclusion, as a substitute for FO. Yellowtail Kingfish growth and growth factor gene expression was compared with fish fed a diet containing 100% FO.

Two experiments were conducted separately at optimal (22 oC; 33 d) and sub-optimal (18 oC; 34 d) temperatures with mean initial fish weights of 95.6 ± 0.1 g and 101 ± 0.1 g respectively. At 22 oC Yellowtail Kingfish fed the 50% PO diet grew significantly larger (281.2 ± 1.2 g) than individuals fed the 100% FO diet (266.9 ± 5.9 g). Inclusion of CO at 50% produced equivalent weight gain to the 100% FO diet, however, 100% inclusion of CO produced poor performance in both experiments. Trends in gene expression reflected the response in weight gain to alternative lipids. A positive relationship between hepatic IGF-I mRNA levels and weight gain and also hepatic IGFBP-1 mRNA and weight gain was found. A positive correlation between hepatic IGF-I and IGFBP-1 mRNA levels was also found. Irrespective of diet, fish grew larger at 22 oC than at 18 oC. The findings of this research indicate that improved diet formulations for Yellowtail Kingfish may be achieved through the inclusion of alternative lipid sources and that IGF-I mRNA may be used as a rapid indicator of growth in this species.

Summary

In this study the suitability of canola oil (CO) and poultry fat (PO) as alternatives to fish oil (FO) was assessed. Furthermore, a real-time RT-qPCR assay to detect hepatic insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-1 (IGFBP-1) was developed. Four isoproteic (450 g kg-1), isolipidic (250 g kg-1) dry extruded diets were formulated to contain PO or CO at 50 or 100% inclusion, as a substitute for FO. Yellowtail Kingfish growth and growth factor gene expression was compared with fish fed a diet containing 100% FO.

Two experiments were conducted separately at optimal (22 oC; 33 d) and sub-optimal (18 oC; 34 d) temperatures with mean initial fish weights of 95.6 ± 0.1 g and 101 ± 0.1 g respectively. At 22 oC Yellowtail Kingfish fed the 50% PO diet grew significantly larger (281.2 ± 1.2 g) than individuals fed the 100% FO diet (266.9 ± 5.9 g). Inclusion of CO at 50% produced equivalent weight gain to the 100% FO diet, however, 100% inclusion of CO produced poor performance in both experiments. Trends in gene expression reflected the response in weight gain to alternative lipids. A positive relationship between hepatic IGF-I mRNA levels and weight gain and also hepatic IGFBP-1 mRNA and weight gain was found. A positive correlation between hepatic IGF-I and IGFBP-1 mRNA levels was also found. Irrespective of diet, fish grew larger at 22 oC than at 18 oC. The findings of this research indicate that improved diet formulations for Yellowtail Kingfish may be achieved through the inclusion of alternative lipid sources and that IGF-I mRNA may be used as a rapid indicator of growth in this species.

Summary

In this study the suitability of canola oil (CO) and poultry fat (PO) as alternatives to fish oil (FO) was assessed. Furthermore, a real-time RT-qPCR assay to detect hepatic insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-1 (IGFBP-1) was developed. Four isoproteic (450 g kg-1), isolipidic (250 g kg-1) dry extruded diets were formulated to contain PO or CO at 50 or 100% inclusion, as a substitute for FO. Yellowtail Kingfish growth and growth factor gene expression was compared with fish fed a diet containing 100% FO.

Two experiments were conducted separately at optimal (22 oC; 33 d) and sub-optimal (18 oC; 34 d) temperatures with mean initial fish weights of 95.6 ± 0.1 g and 101 ± 0.1 g respectively. At 22 oC Yellowtail Kingfish fed the 50% PO diet grew significantly larger (281.2 ± 1.2 g) than individuals fed the 100% FO diet (266.9 ± 5.9 g). Inclusion of CO at 50% produced equivalent weight gain to the 100% FO diet, however, 100% inclusion of CO produced poor performance in both experiments. Trends in gene expression reflected the response in weight gain to alternative lipids. A positive relationship between hepatic IGF-I mRNA levels and weight gain and also hepatic IGFBP-1 mRNA and weight gain was found. A positive correlation between hepatic IGF-I and IGFBP-1 mRNA levels was also found. Irrespective of diet, fish grew larger at 22 oC than at 18 oC. The findings of this research indicate that improved diet formulations for Yellowtail Kingfish may be achieved through the inclusion of alternative lipid sources and that IGF-I mRNA may be used as a rapid indicator of growth in this species.

Summary

In this study the suitability of canola oil (CO) and poultry fat (PO) as alternatives to fish oil (FO) was assessed. Furthermore, a real-time RT-qPCR assay to detect hepatic insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-1 (IGFBP-1) was developed. Four isoproteic (450 g kg-1), isolipidic (250 g kg-1) dry extruded diets were formulated to contain PO or CO at 50 or 100% inclusion, as a substitute for FO. Yellowtail Kingfish growth and growth factor gene expression was compared with fish fed a diet containing 100% FO.

Two experiments were conducted separately at optimal (22 oC; 33 d) and sub-optimal (18 oC; 34 d) temperatures with mean initial fish weights of 95.6 ± 0.1 g and 101 ± 0.1 g respectively. At 22 oC Yellowtail Kingfish fed the 50% PO diet grew significantly larger (281.2 ± 1.2 g) than individuals fed the 100% FO diet (266.9 ± 5.9 g). Inclusion of CO at 50% produced equivalent weight gain to the 100% FO diet, however, 100% inclusion of CO produced poor performance in both experiments. Trends in gene expression reflected the response in weight gain to alternative lipids. A positive relationship between hepatic IGF-I mRNA levels and weight gain and also hepatic IGFBP-1 mRNA and weight gain was found. A positive correlation between hepatic IGF-I and IGFBP-1 mRNA levels was also found. Irrespective of diet, fish grew larger at 22 oC than at 18 oC. The findings of this research indicate that improved diet formulations for Yellowtail Kingfish may be achieved through the inclusion of alternative lipid sources and that IGF-I mRNA may be used as a rapid indicator of growth in this species.

Summary

In this study the suitability of canola oil (CO) and poultry fat (PO) as alternatives to fish oil (FO) was assessed. Furthermore, a real-time RT-qPCR assay to detect hepatic insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-1 (IGFBP-1) was developed. Four isoproteic (450 g kg-1), isolipidic (250 g kg-1) dry extruded diets were formulated to contain PO or CO at 50 or 100% inclusion, as a substitute for FO. Yellowtail Kingfish growth and growth factor gene expression was compared with fish fed a diet containing 100% FO.

Two experiments were conducted separately at optimal (22 oC; 33 d) and sub-optimal (18 oC; 34 d) temperatures with mean initial fish weights of 95.6 ± 0.1 g and 101 ± 0.1 g respectively. At 22 oC Yellowtail Kingfish fed the 50% PO diet grew significantly larger (281.2 ± 1.2 g) than individuals fed the 100% FO diet (266.9 ± 5.9 g). Inclusion of CO at 50% produced equivalent weight gain to the 100% FO diet, however, 100% inclusion of CO produced poor performance in both experiments. Trends in gene expression reflected the response in weight gain to alternative lipids. A positive relationship between hepatic IGF-I mRNA levels and weight gain and also hepatic IGFBP-1 mRNA and weight gain was found. A positive correlation between hepatic IGF-I and IGFBP-1 mRNA levels was also found. Irrespective of diet, fish grew larger at 22 oC than at 18 oC. The findings of this research indicate that improved diet formulations for Yellowtail Kingfish may be achieved through the inclusion of alternative lipid sources and that IGF-I mRNA may be used as a rapid indicator of growth in this species.

Summary

In this study the suitability of canola oil (CO) and poultry fat (PO) as alternatives to fish oil (FO) was assessed. Furthermore, a real-time RT-qPCR assay to detect hepatic insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-1 (IGFBP-1) was developed. Four isoproteic (450 g kg-1), isolipidic (250 g kg-1) dry extruded diets were formulated to contain PO or CO at 50 or 100% inclusion, as a substitute for FO. Yellowtail Kingfish growth and growth factor gene expression was compared with fish fed a diet containing 100% FO.

Two experiments were conducted separately at optimal (22 oC; 33 d) and sub-optimal (18 oC; 34 d) temperatures with mean initial fish weights of 95.6 ± 0.1 g and 101 ± 0.1 g respectively. At 22 oC Yellowtail Kingfish fed the 50% PO diet grew significantly larger (281.2 ± 1.2 g) than individuals fed the 100% FO diet (266.9 ± 5.9 g). Inclusion of CO at 50% produced equivalent weight gain to the 100% FO diet, however, 100% inclusion of CO produced poor performance in both experiments. Trends in gene expression reflected the response in weight gain to alternative lipids. A positive relationship between hepatic IGF-I mRNA levels and weight gain and also hepatic IGFBP-1 mRNA and weight gain was found. A positive correlation between hepatic IGF-I and IGFBP-1 mRNA levels was also found. Irrespective of diet, fish grew larger at 22 oC than at 18 oC. The findings of this research indicate that improved diet formulations for Yellowtail Kingfish may be achieved through the inclusion of alternative lipid sources and that IGF-I mRNA may be used as a rapid indicator of growth in this species.

Summary

In this study the suitability of canola oil (CO) and poultry fat (PO) as alternatives to fish oil (FO) was assessed. Furthermore, a real-time RT-qPCR assay to detect hepatic insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-1 (IGFBP-1) was developed. Four isoproteic (450 g kg-1), isolipidic (250 g kg-1) dry extruded diets were formulated to contain PO or CO at 50 or 100% inclusion, as a substitute for FO. Yellowtail Kingfish growth and growth factor gene expression was compared with fish fed a diet containing 100% FO.

Two experiments were conducted separately at optimal (22 oC; 33 d) and sub-optimal (18 oC; 34 d) temperatures with mean initial fish weights of 95.6 ± 0.1 g and 101 ± 0.1 g respectively. At 22 oC Yellowtail Kingfish fed the 50% PO diet grew significantly larger (281.2 ± 1.2 g) than individuals fed the 100% FO diet (266.9 ± 5.9 g). Inclusion of CO at 50% produced equivalent weight gain to the 100% FO diet, however, 100% inclusion of CO produced poor performance in both experiments. Trends in gene expression reflected the response in weight gain to alternative lipids. A positive relationship between hepatic IGF-I mRNA levels and weight gain and also hepatic IGFBP-1 mRNA and weight gain was found. A positive correlation between hepatic IGF-I and IGFBP-1 mRNA levels was also found. Irrespective of diet, fish grew larger at 22 oC than at 18 oC. The findings of this research indicate that improved diet formulations for Yellowtail Kingfish may be achieved through the inclusion of alternative lipid sources and that IGF-I mRNA may be used as a rapid indicator of growth in this species.

Summary

In this study the suitability of canola oil (CO) and poultry fat (PO) as alternatives to fish oil (FO) was assessed. Furthermore, a real-time RT-qPCR assay to detect hepatic insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-1 (IGFBP-1) was developed. Four isoproteic (450 g kg-1), isolipidic (250 g kg-1) dry extruded diets were formulated to contain PO or CO at 50 or 100% inclusion, as a substitute for FO. Yellowtail Kingfish growth and growth factor gene expression was compared with fish fed a diet containing 100% FO.

Two experiments were conducted separately at optimal (22 oC; 33 d) and sub-optimal (18 oC; 34 d) temperatures with mean initial fish weights of 95.6 ± 0.1 g and 101 ± 0.1 g respectively. At 22 oC Yellowtail Kingfish fed the 50% PO diet grew significantly larger (281.2 ± 1.2 g) than individuals fed the 100% FO diet (266.9 ± 5.9 g). Inclusion of CO at 50% produced equivalent weight gain to the 100% FO diet, however, 100% inclusion of CO produced poor performance in both experiments. Trends in gene expression reflected the response in weight gain to alternative lipids. A positive relationship between hepatic IGF-I mRNA levels and weight gain and also hepatic IGFBP-1 mRNA and weight gain was found. A positive correlation between hepatic IGF-I and IGFBP-1 mRNA levels was also found. Irrespective of diet, fish grew larger at 22 oC than at 18 oC. The findings of this research indicate that improved diet formulations for Yellowtail Kingfish may be achieved through the inclusion of alternative lipid sources and that IGF-I mRNA may be used as a rapid indicator of growth in this species.

Summary

In this study the suitability of canola oil (CO) and poultry fat (PO) as alternatives to fish oil (FO) was assessed. Furthermore, a real-time RT-qPCR assay to detect hepatic insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-1 (IGFBP-1) was developed. Four isoproteic (450 g kg-1), isolipidic (250 g kg-1) dry extruded diets were formulated to contain PO or CO at 50 or 100% inclusion, as a substitute for FO. Yellowtail Kingfish growth and growth factor gene expression was compared with fish fed a diet containing 100% FO.

Two experiments were conducted separately at optimal (22 oC; 33 d) and sub-optimal (18 oC; 34 d) temperatures with mean initial fish weights of 95.6 ± 0.1 g and 101 ± 0.1 g respectively. At 22 oC Yellowtail Kingfish fed the 50% PO diet grew significantly larger (281.2 ± 1.2 g) than individuals fed the 100% FO diet (266.9 ± 5.9 g). Inclusion of CO at 50% produced equivalent weight gain to the 100% FO diet, however, 100% inclusion of CO produced poor performance in both experiments. Trends in gene expression reflected the response in weight gain to alternative lipids. A positive relationship between hepatic IGF-I mRNA levels and weight gain and also hepatic IGFBP-1 mRNA and weight gain was found. A positive correlation between hepatic IGF-I and IGFBP-1 mRNA levels was also found. Irrespective of diet, fish grew larger at 22 oC than at 18 oC. The findings of this research indicate that improved diet formulations for Yellowtail Kingfish may be achieved through the inclusion of alternative lipid sources and that IGF-I mRNA may be used as a rapid indicator of growth in this species.

Summary

In this study the suitability of canola oil (CO) and poultry fat (PO) as alternatives to fish oil (FO) was assessed. Furthermore, a real-time RT-qPCR assay to detect hepatic insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-1 (IGFBP-1) was developed. Four isoproteic (450 g kg-1), isolipidic (250 g kg-1) dry extruded diets were formulated to contain PO or CO at 50 or 100% inclusion, as a substitute for FO. Yellowtail Kingfish growth and growth factor gene expression was compared with fish fed a diet containing 100% FO.

Two experiments were conducted separately at optimal (22 oC; 33 d) and sub-optimal (18 oC; 34 d) temperatures with mean initial fish weights of 95.6 ± 0.1 g and 101 ± 0.1 g respectively. At 22 oC Yellowtail Kingfish fed the 50% PO diet grew significantly larger (281.2 ± 1.2 g) than individuals fed the 100% FO diet (266.9 ± 5.9 g). Inclusion of CO at 50% produced equivalent weight gain to the 100% FO diet, however, 100% inclusion of CO produced poor performance in both experiments. Trends in gene expression reflected the response in weight gain to alternative lipids. A positive relationship between hepatic IGF-I mRNA levels and weight gain and also hepatic IGFBP-1 mRNA and weight gain was found. A positive correlation between hepatic IGF-I and IGFBP-1 mRNA levels was also found. Irrespective of diet, fish grew larger at 22 oC than at 18 oC. The findings of this research indicate that improved diet formulations for Yellowtail Kingfish may be achieved through the inclusion of alternative lipid sources and that IGF-I mRNA may be used as a rapid indicator of growth in this species.

Summary

In this study the suitability of canola oil (CO) and poultry fat (PO) as alternatives to fish oil (FO) was assessed. Furthermore, a real-time RT-qPCR assay to detect hepatic insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-1 (IGFBP-1) was developed. Four isoproteic (450 g kg-1), isolipidic (250 g kg-1) dry extruded diets were formulated to contain PO or CO at 50 or 100% inclusion, as a substitute for FO. Yellowtail Kingfish growth and growth factor gene expression was compared with fish fed a diet containing 100% FO.

Two experiments were conducted separately at optimal (22 oC; 33 d) and sub-optimal (18 oC; 34 d) temperatures with mean initial fish weights of 95.6 ± 0.1 g and 101 ± 0.1 g respectively. At 22 oC Yellowtail Kingfish fed the 50% PO diet grew significantly larger (281.2 ± 1.2 g) than individuals fed the 100% FO diet (266.9 ± 5.9 g). Inclusion of CO at 50% produced equivalent weight gain to the 100% FO diet, however, 100% inclusion of CO produced poor performance in both experiments. Trends in gene expression reflected the response in weight gain to alternative lipids. A positive relationship between hepatic IGF-I mRNA levels and weight gain and also hepatic IGFBP-1 mRNA and weight gain was found. A positive correlation between hepatic IGF-I and IGFBP-1 mRNA levels was also found. Irrespective of diet, fish grew larger at 22 oC than at 18 oC. The findings of this research indicate that improved diet formulations for Yellowtail Kingfish may be achieved through the inclusion of alternative lipid sources and that IGF-I mRNA may be used as a rapid indicator of growth in this species.

Summary

In this study the suitability of canola oil (CO) and poultry fat (PO) as alternatives to fish oil (FO) was assessed. Furthermore, a real-time RT-qPCR assay to detect hepatic insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-1 (IGFBP-1) was developed. Four isoproteic (450 g kg-1), isolipidic (250 g kg-1) dry extruded diets were formulated to contain PO or CO at 50 or 100% inclusion, as a substitute for FO. Yellowtail Kingfish growth and growth factor gene expression was compared with fish fed a diet containing 100% FO.

Two experiments were conducted separately at optimal (22 oC; 33 d) and sub-optimal (18 oC; 34 d) temperatures with mean initial fish weights of 95.6 ± 0.1 g and 101 ± 0.1 g respectively. At 22 oC Yellowtail Kingfish fed the 50% PO diet grew significantly larger (281.2 ± 1.2 g) than individuals fed the 100% FO diet (266.9 ± 5.9 g). Inclusion of CO at 50% produced equivalent weight gain to the 100% FO diet, however, 100% inclusion of CO produced poor performance in both experiments. Trends in gene expression reflected the response in weight gain to alternative lipids. A positive relationship between hepatic IGF-I mRNA levels and weight gain and also hepatic IGFBP-1 mRNA and weight gain was found. A positive correlation between hepatic IGF-I and IGFBP-1 mRNA levels was also found. Irrespective of diet, fish grew larger at 22 oC than at 18 oC. The findings of this research indicate that improved diet formulations for Yellowtail Kingfish may be achieved through the inclusion of alternative lipid sources and that IGF-I mRNA may be used as a rapid indicator of growth in this species.

Summary

In this study the suitability of canola oil (CO) and poultry fat (PO) as alternatives to fish oil (FO) was assessed. Furthermore, a real-time RT-qPCR assay to detect hepatic insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-1 (IGFBP-1) was developed. Four isoproteic (450 g kg-1), isolipidic (250 g kg-1) dry extruded diets were formulated to contain PO or CO at 50 or 100% inclusion, as a substitute for FO. Yellowtail Kingfish growth and growth factor gene expression was compared with fish fed a diet containing 100% FO.

Two experiments were conducted separately at optimal (22 oC; 33 d) and sub-optimal (18 oC; 34 d) temperatures with mean initial fish weights of 95.6 ± 0.1 g and 101 ± 0.1 g respectively. At 22 oC Yellowtail Kingfish fed the 50% PO diet grew significantly larger (281.2 ± 1.2 g) than individuals fed the 100% FO diet (266.9 ± 5.9 g). Inclusion of CO at 50% produced equivalent weight gain to the 100% FO diet, however, 100% inclusion of CO produced poor performance in both experiments. Trends in gene expression reflected the response in weight gain to alternative lipids. A positive relationship between hepatic IGF-I mRNA levels and weight gain and also hepatic IGFBP-1 mRNA and weight gain was found. A positive correlation between hepatic IGF-I and IGFBP-1 mRNA levels was also found. Irrespective of diet, fish grew larger at 22 oC than at 18 oC. The findings of this research indicate that improved diet formulations for Yellowtail Kingfish may be achieved through the inclusion of alternative lipid sources and that IGF-I mRNA may be used as a rapid indicator of growth in this species.

Summary

In this study the suitability of canola oil (CO) and poultry fat (PO) as alternatives to fish oil (FO) was assessed. Furthermore, a real-time RT-qPCR assay to detect hepatic insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-1 (IGFBP-1) was developed. Four isoproteic (450 g kg-1), isolipidic (250 g kg-1) dry extruded diets were formulated to contain PO or CO at 50 or 100% inclusion, as a substitute for FO. Yellowtail Kingfish growth and growth factor gene expression was compared with fish fed a diet containing 100% FO.

Two experiments were conducted separately at optimal (22 oC; 33 d) and sub-optimal (18 oC; 34 d) temperatures with mean initial fish weights of 95.6 ± 0.1 g and 101 ± 0.1 g respectively. At 22 oC Yellowtail Kingfish fed the 50% PO diet grew significantly larger (281.2 ± 1.2 g) than individuals fed the 100% FO diet (266.9 ± 5.9 g). Inclusion of CO at 50% produced equivalent weight gain to the 100% FO diet, however, 100% inclusion of CO produced poor performance in both experiments. Trends in gene expression reflected the response in weight gain to alternative lipids. A positive relationship between hepatic IGF-I mRNA levels and weight gain and also hepatic IGFBP-1 mRNA and weight gain was found. A positive correlation between hepatic IGF-I and IGFBP-1 mRNA levels was also found. Irrespective of diet, fish grew larger at 22 oC than at 18 oC. The findings of this research indicate that improved diet formulations for Yellowtail Kingfish may be achieved through the inclusion of alternative lipid sources and that IGF-I mRNA may be used as a rapid indicator of growth in this species.

Summary

In this study the suitability of canola oil (CO) and poultry fat (PO) as alternatives to fish oil (FO) was assessed. Furthermore, a real-time RT-qPCR assay to detect hepatic insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-1 (IGFBP-1) was developed. Four isoproteic (450 g kg-1), isolipidic (250 g kg-1) dry extruded diets were formulated to contain PO or CO at 50 or 100% inclusion, as a substitute for FO. Yellowtail Kingfish growth and growth factor gene expression was compared with fish fed a diet containing 100% FO.

Two experiments were conducted separately at optimal (22 oC; 33 d) and sub-optimal (18 oC; 34 d) temperatures with mean initial fish weights of 95.6 ± 0.1 g and 101 ± 0.1 g respectively. At 22 oC Yellowtail Kingfish fed the 50% PO diet grew significantly larger (281.2 ± 1.2 g) than individuals fed the 100% FO diet (266.9 ± 5.9 g). Inclusion of CO at 50% produced equivalent weight gain to the 100% FO diet, however, 100% inclusion of CO produced poor performance in both experiments. Trends in gene expression reflected the response in weight gain to alternative lipids. A positive relationship between hepatic IGF-I mRNA levels and weight gain and also hepatic IGFBP-1 mRNA and weight gain was found. A positive correlation between hepatic IGF-I and IGFBP-1 mRNA levels was also found. Irrespective of diet, fish grew larger at 22 oC than at 18 oC. The findings of this research indicate that improved diet formulations for Yellowtail Kingfish may be achieved through the inclusion of alternative lipid sources and that IGF-I mRNA may be used as a rapid indicator of growth in this species.

The findings of this research indicate that improved diet formulations for Yellowtail Kingfish may be achieved through the inclusion of alternative lipid sources and that IGF-I mRNA may be used as a rapid indicator of growth in this species.

Summary

In this study the suitability of canola oil (CO) and poultry fat (PO) as alternatives to fish oil (FO) was assessed. Furthermore, a real-time RT-qPCR assay to detect hepatic insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-1 (IGFBP-1) was developed. Four isoproteic (450 g kg-1), isolipidic (250 g kg-1) dry extruded diets were formulated to contain PO or CO at 50 or 100% inclusion, as a substitute for FO. Yellowtail Kingfish growth and growth factor gene expression was compared with fish fed a diet containing 100% FO.

Two experiments were conducted separately at optimal (22 oC; 33 d) and sub-optimal (18 oC; 34 d) temperatures with mean initial fish weights of 95.6 ± 0.1 g and 101 ± 0.1 g respectively. At 22 oC Yellowtail Kingfish fed the 50% PO diet grew significantly larger (281.2 ± 1.2 g) than individuals fed the 100% FO diet (266.9 ± 5.9 g). Inclusion of CO at 50% produced equivalent weight gain to the 100% FO diet, however, 100% inclusion of CO produced poor performance in both experiments. Trends in gene expression reflected the response in weight gain to alternative lipids. A positive relationship between hepatic IGF-I mRNA levels and weight gain and also hepatic IGFBP-1 mRNA and weight gain was found. A positive correlation between hepatic IGF-I and IGFBP-1 mRNA levels was also found. Irrespective of diet, fish grew larger at 22 oC than at 18 oC. The findings of this research indicate that improved diet formulations for Yellowtail Kingfish may be achieved through the inclusion of alternative lipid sources and that IGF-I mRNA may be used as a rapid indicator of growth in this species.

Summary

Yellowtail Kingfish is an emerging aquaculture species, and there is an increase in the demand for the fish, both for recreational fishing and for export purposes. This has led to the growth of the aquaculture industry that specialises in culture of yellowtail kingfish in South Australia. Currently very little is known about the physiological properties of yellowtail kingfish, and most data that has been generated on the fish has primarily been in Japan, where most of the scientific articles are written in Japanese.

There is currently very limited supply of microalgae in Australia for use in commercial applications, and development is underway to encourage growth of the microalgae industry with a specific focus on developing a biorefinery system. One of the main aspects of the biorefinery system will be to use waste generated by the production of biofuels in other industries which will provide value addition to the waste products from the production of biodiesel.

Summary

Yellowtail Kingfish (Seriola lalandi) have been farmed for over a decade in sea cages in the waters of Spencer Gulf, South Australia. Substantial fluctuations of the water temperature in Spencer Gulf occur, reaching 24ºC in summer and dropping below 12ºC in winter. Inclusions of soybean meal in feeds for Yellowtail kingfish are becoming common. High dietary inclusions of soybean meal coupled with low water temperatures are thought to contribute to the development of sub-acute enteritis in the hindgut of Yellowtail kingfish. Prior to this study, the role the mucus layer plays in protecting the underlying mucosa had not been investigated in fish.

In this study, fish were fed increasing dietary inclusion levels of solvent extracted soybean meal (SE SBM), to apparent satiation twice daily, at water temperatures of 18ºC and 22ºC for 34 days. At the conclusion of the study, the intestinal tract was removed, with no fish exhibiting visual features of hindgut inflammation. Samples were collected for histological evaluation, revealing a significant reduction in mucus layer thickness in the hindgut of fish fed increasing dietary inclusion levels of SE SBM. Water temperature had a significant effect on mucin composition. A more profound increase in neutral mucins in the hindgut was observed at 18ºC, while a more profound increase of acidic mucins was evident at 22ºC. Fish fed 20% and 30% dietary inclusions of SE SBM at 18ºC had a significant increase in goblet cell number. Although sub-acute enteritis was not induced in this study, it is evident that the intestinal barrier was compromised. Based on observations from this study, SE SBM inclusion levels in the diet for Yellowtail kingfish of this size range should be restricted to 10% at 18°C and 20% at 22°C. Further studies are required to assess alteration to intestinal morphology and the development of sub-acute enteritis in Yellowtail kingfish reared in colder waters indicative of those experienced during winter months.

Summary

Yellowtail Kingfish (Seriola lalandi) have been farmed for over a decade in sea cages in the waters of Spencer Gulf, South Australia. Substantial fluctuations of the water temperature in Spencer Gulf occur, reaching 24ºC in summer and dropping below 12ºC in winter. Inclusions of soybean meal in feeds for Yellowtail kingfish are becoming common. High dietary inclusions of soybean meal coupled with low water temperatures are thought to contribute to the development of sub-acute enteritis in the hindgut of Yellowtail kingfish. Prior to this study, the role the mucus layer plays in protecting the underlying mucosa had not been investigated in fish.

Further studies are required to assess alteration to intestinal morphology and the development of sub-acute enteritis in Yellowtail kingfish reared in colder waters indicative of those experienced during winter months.

Summary

One of the most important global food sources is seafood, and in particular saltwater seafood. However, while demand is increasing, the supplies of wild caught sources are depleted and there is now an increased need to source seafood species, such as prawns from farmed stocks. Aquaculture has become a reliable source for many species, particularly prawns. It has been identified that consumers around the globe have many preconceived and often negative perceptions of farmed prawns, which is preventing the demand and growth of the industry. Australia is a world leader in best practice management and product quality, with a vast amount of ideal topographical locations for prawn farming. However, despite these positives, it continues to have one of the smallest gross production outputs of farmed prawns. Thus it is important to determine the factors that encourage positive behavioural intentions toward this product. Many studies have demonstrated the power that consumer perceptions have on both customer satisfaction and behavioural intentions. Trust has also been identified as having significance influence on these elements. Therefore, this study measures the perceptions, trust, satisfaction and behavioural intentions of customers of Australian farmed prawns within South East Queensland.

A total of 211 respondents from 10 locations participated in this study. The findings show that Trust has a very large impact on Customer Satisfaction, Behavioural Intentions, Customer Perceptions of Product- Physical attributes, Product- Health aspects, Price, Place, Marketing Communications, Process, Physical Evidence and People of the customers of Australian farmed prawns within South East Queensland. Another illuminating finding was that Customer Perceptions of Product- Physical attributes and Price were the two key variables of eight Customer Perception variables that have a significant influence on both Customer Satisfaction and Behavioral Intentions of customers of Australian farmed prawns within South East Queensland.

Summary

Body colouration, an important survival, mate selection and communication mechanism for animals in the wild, has also significant commercial implications. In aquaculture, a darker body colour in prawns can increase farm profitability by AU$ 2-4 dollar per kilo of prawns. Therefore, there is a strong commercial interest in increasing colour intensity of prawns grown in captivity. In this study, the focus was on F. merguiensis, and the determination of factors that could be involved in colour formation in this species.

Molecular techniques were employed to clone and isolate crustacyanin subunits, genes known to be responsible for colouration in other crustacean species, from the muscle/cuticle tissue of F. merguiensis prawns and to develop gene specific primers to quantify the levels of crustacyanin gene expression in the cuticle of prawns displaying three different colour phenotypes (albino, light and dark).

The sequences encoding for the crustacyanin subunits A and C were isolated from the cuticle tissue in F. merguiensis and their expression levels characterised in prawns displaying different colouration patterns.

Summary

Body colouration, an important survival, mate selection and communication mechanism for animals in the wild, has also significant commercial implications. In aquaculture, a darker body colour in prawns can increase farm profitability by AU$ 2-4 dollar per kilo of prawns. Therefore, there is a strong commercial interest in increasing colour intensity of prawns grown in captivity. In this study, the focus was on F. merguiensis, and the determination of factors that could be involved in colour formation in this species.
