Need

Yellowtail kingfish (YTK) farming is identified nationally as the greatest opportunity for new aquaculture development in the next few decades through substantial increases in farmed area and product, and use of aquafeeds, resulting in growth in regional economies and employment. Within 10 years, YTK production is expected to increase by 34,000 tonnes, worth $440 million, and using 68,000 tonnes of aquafeed worth $136 million. The key challenge to achieving this growth is for industry to diversify its focus from supplying only the relatively small volume, high price sashimi market to the larger volume, lower price Australian ‘white fish’ market, while enhancing farm productivity and reducing operating costs to maintain profitability.

This project will enable industry to grow its position by developing more cost effective, sustainable feeds and feeding strategies to enhance YTK growth and health. It will also network three key Australian YTK aquaculture companies and their aligned research institutions (SA NSW and WA). The WA producer Indian Ocean Fresh will participate in the first year with the view to invest further in subsequent years.

As such, this project will meet the designated ‘Rural Research & Development for Profit Programme’ objectives:
1. “Generating knowledge, technologies, products or processes that benefit primary producers",
2. “Establishing and fostering industry and research collaborations that form the basis for ongoing innovation and growth of Australian agriculture”.

The key Activities will address the YTK industry's common R&D priorities through three components/themes:
1. Economically sustainable feeds and improved diet formulation (NUTRITION);
2. Improved FEEDING STRATEGIES to increase profit; and
3. Improving nutritional HEALTH to boost productivity.

Objectives

1. Benchmark the performance of yellowtail kingfish grown in waters representative of the warm waters of the mid west of Western Australia
2. Determine the effect of different commercial diets on the health status of yellowtail kingfish
3. Compare performance of YTK derived from WA and SA broodstock

Summary

This set of experiments compared the growth performance, survival and health of yellowtail kingfish (YTK) sourced from two different hatcheries (Strain 1 and Strain 2) fed on various diets over a commercially relevant time period of 56 weeks (ca. 13 months). Fish health was assessed routinely throughout the trial using histology, haematology, blood biochemistry and by measuring various immune parameters via both flow cytometry and more classical techniques.
This project demonstrated significant differences in the performance of YTK fed different diets across a commercially relevant time frame. It has generated growth and FCR data that are superior to those reported previously and that will be used to generate more industry-relevant growth models for optimising feeding and food conversion ratios in warm-water environments. The project has been highly successfully in generating large volumes of baseline data on health and has generated new techniques and skill sets within Western Australia that will be of key importance to the developing YTK industry in this state. The project has identified several areas for future work that have potential in improving YTK health and subsequently the profitability and sustainability of the industry.

NEAO: addressing current health issues confronting warm water culture of yellowtail kingfish

Need

Yellowtail kingfish (YTK) farming is identified nationally as the greatest opportunity for new aquaculture development in the next few decades through substantial increases in farmed area. This will deliver substantial increase in product to market, and increased use of locally produced aqua feeds, resulting in growth in regional economies and employment. Within 10 years, YTK production is expected to increase by 34,000 tonnes, worth $440 million, and using 68,000 tonnes of aqua feed worth $136 million.

The culture of this species in warm water has many advantages, yet creates some unique challenges. Managing flukes in the warm water environment is currently a major cost burden on the YTK industry because the life cycle duration of the monogenean parasites is more rapid, therefore requiring more frequent bathing. Moreover, the standard management practice of bathing in hydrogen peroxide carries a greater risk in warm water and must therefore be optimised and more carefully managed. Whilst we are aware that some research has been conducted previously on peroxide optimisation for YTK, this information has not been made available to WA YTK farmers and has had a significant financial impact on the fledgling WA industry.

Bacterial diseases are also problematic in warm water YTK farming. Photobacterium damselae ssp damselae is a recurring problem in warm water culture and outbreaks of this disease are often associated with Vibrio harveyi. An autogenous vaccine has been developed for Photobacterium, but its efficacy has not been tested experimentally.

Objectives

1. Optimise the use of hydrogen peroxide to treat flukes in warm water
2. Investigate alternative fluke management methods to hydrogen peroxide in warm water
3. Quantify the benefits of an autogenous vaccine against Photobacterium damselae subspecies damselae.
4. Determine in vitro whether interactions exist between Photobacterium damselae subspecies damselae and Vibrio harveyi that influence virulence

Summary

This project addressed a number of key issues associated with the culture of yellowtail kingfish (Seriola lalandi, YTK) in warm water, including optimising the use of hydrogen peroxide (which is more toxic in warm water), investigating alternatives to the management of monogenean flukes (Neobenedenia girellae and Zeuxapta seriolae) in warm water and several aspects relating to a better understanding of the bacteria which cause disease in YTK, including an assessment of an industry-funded autogenous vaccine against the pathogenic bacteria Photobacterium damsellae subspecies damsellae.
