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.

Growing a profitable, innovative, collaborative Australian Yellowtail Kingfish aquaculture industry: bringing ‘white’ fish to the market. WA Component

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...
