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...

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

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...

Summary

High incidences of malformation and low level survival are common during Yellowtail Kingfish larviculture and it has been hypothesised that this is a result of excessive harmful bacterial loads within the culture tanks. The current rate of malformation and survival continues to impact heavily on the price of juvenile kingfish. There is a need therefore, to reduce the incidence of such malformations and increase the overall survival rate to reduce the cost of juvenile production and improve the quality and quantity of fish being put to sea.

The researcher Dr Michael, travelled to the University of Miami’s Experimental Marine Hatchery (UMEH) to work and train under the supervision of Professor Daniel Benetti and alongside his Masters student, Mr Zack Daugherty, the subject of whose thesis is the use of clay particles in larval rearing of Cobia. Over the past 12 months Mr Daugherty has been conducting preliminary trials on the best methods of handling and delivering clay particles to larval rearing tanks.

During the 30 day visit, Dr Michael was able to further develop these techniques with Mr Daugherty prior to conducting a 13 day replicated research trial that assessed the potential bacterial reducing properties of using clay during Cobia larval rearing compared with the standard green water method that uses concentrated nannochloropsis paste. Using clay particles to replace nannochloropsis paste during the green water phase of Cobia larval culture was recently investigated. The results clearly showed that using this media has the potential to greatly reduce bacterial loads within larval tanks and reduce costs associated with purchasing algal paste concentrates.

SCRC: Development of Yellowtail Kingfish aquaculture in Western Australia: Removal of barriers to profitable production.

Sub-Project 1: Genetics DNA analyses were used to develop a mating strategy to avoid inbreeding among the limited number of existing captive broodstock in WA. A genetic management workshop was carried out in with ACAAR and WA Industry and used to inform attendees about basic genetic management...

New technologies for sustainable commercial finfish culture

We have demonstrated that yields of 10 tonnes of fish per hectare cannot be sustainably achieved in static, autotrophic saline (14 ppt) ponds (i.e. ponds dominated by photosynthetic organisms) over a 3-4 month production cycle, despite the removal of settable wastes from the SIFTS. The outcome of...

Restocking of the Blackwood River Estuary with black bream (Acanthopagrus butcheri)

The results of this study show that hatchery-reared Black Bream can be used to enhance the stock of the population of this commercially and recreationally important species in the Blackwood River Estuary in which it has become depleted. An initial trial of different stains demonstrated that alizarin...

West Australian Dhufish

Need

* The WA dhufish is a premium quality finfish with attributes suitable for aquaculture. In addition to the attractiveness of the species for aquaculture, Fisheries WA (FWA) have recently identified dhufish as a species "at risk" and requiring close monitoring. The development of reliable culture technology for dhufish and the subsequent establishment of a dhufish culture industry has potential to alleviate commercial fishing pressure.

* Jurien Fishfarmers PTY LTD has considerable investment in marine finfish aquaculture in WA. They currently have black bream and pink snapper in seacage off Jurien and are looking at a range of other higher value species. This company and others have considerable commercial interest in the development of high value species for aquaculture. Dhufish is one these target species.

* Previous work has shown that WA dhufish can be cultured successfully; however, production remains unreliable. It is therefore necessary to extend this work to develop reliable and cost-effective techniques for egg production, larval rearing, weaning and grow-out.

* Two FRDC funded research projects are in progress. One study is addressing health issues in WA dhufish (eg gonad parasite, exophthalmia). The other is examining the development of the eye with a view to optimising culture parameters. The success and application of these projects will be limited if the FMC-based dhufish culture project (this current application) is not continued.

* Domestication is known to greatly improve success of reproduction in captivity. The 94 eighteen-month-old F1 dhufish held at FMC therefore represent a key resource for maximising the benefits from previous FRDC funding and ensuring the success of the project. However, the project needs to be continued in order to grow these fish through to maturity. Research with other species throughout the world and at FMC suggests that the problem of an unreliable supply of good quality eggs from dhufish could be largely overcome when the F1 fish reach maturity (expected in 1999/2000).

Objectives

1. To increase knowledge of species, in particular reproduction, larval rearing and weaning
2. To improve techniques for hormonal induction of ovulation
3. To achieve in-tank spawning of F1 fish
4. To achieve out-of-season spawning of F1 fish
5. To assess capacity of cryopreserved sperm to fertilise eggs
6. To reliably produce fertilised eggs
7. To refine larval rearing techniques
8. To successfully wean larvae
9. To develop a suitable grow-out diet
10. To produce F2 fish
11. To produce a hatchery manual on dhufish culture
