SCRC: Propagation and sea-based growout of sea cucumber stocks in the Northern Territory

Tasmanian Seafoods has identified stock enhancement as a means to improve the viability of sea cucumber harvesting operations in Northern Australia. Successful enhancement of the fishery has the potential increase catches, reduce harvesting time, and improve the operational efficiency and management...

Identification of natural mudworm species in South Australian Pacific oyster (Crassostrea gigas) stocks

Under a joint arrangement between Seafood Services Australia (SSA) and the South Australian Oyster Research Council (SAORC), a project was developed to investigate mudworm in South Australia. A minor mudworm survey was carried out in which between one and three dozen oysters from seven different...

Rock Lobster Post Harvest Subprogram: development of a method for alleviating leg loss during post-harvest handling of rock lobsters

A novel brief application of cold-stunning was identified as a practical method for preventing post-harvest leg loss at several points in the post-harvest handling chain. Using this method, there is potential for the western rock lobster industry to save in excess of $2 million per season in lost...

Diagnosis and prevention of the mid-crop mortality syndrome of pond-reared black tiger prawns (Penaeus monodon)

Project number: 1996-301
Project Status:
Completed
Budget expenditure: $423,716.00
Principal Investigator: Ian Anderson
Organisation: Department of Primary Industries (QLD)
Project start/end date: 8 Aug 1996 - 28 Nov 2003
Contact:
FRDC

Objectives

1. To refine the detection system (hybridisation and PCR) to ensure the best sensitivity and specificity for a test to detect the MCMS agent
2. To clearly identify the risk factors which aggravate the expression of clinical MCMS, including the role of blue green algae
3. To establish a model screening program which allows hatchery and farm production with virus-free prawns
4. To deterine a cost effective, environmentally sensitive disinfection program to eradicate the MCMS agent from farms and hatcheries which will be a model for future disease emergencies

Summary

The project has created knowledge which has led to the outcome of better health management on Australian prawn farms. Changes to farm practices have occurred where whole-farm destocking and pond disinfection are applied as a hygiene practice following a season where crop declines or failures are seen. During, and subsequent to, the project prawn farmers now understand that infectious disease can affect cultured marine prawns in earthen ponds. As a consequence many farmers will submit sick prawns for diagnostic analysis soon after stressed prawns are seen in ponds, not assuming the problems are due to pond environment factors.

The project has contributed to the recovery of the Queensland prawn farm industry from the low production seen in the 1995/96 season of 1,294 tonnes (worth $28.2m) to 1855 tonnes (worth $32.4m) reported in 1998/99. A similar outcome is reflected when Australian marine prawn production is considered; from a low of 1,400 tonnes in 1994/95 to 2,059 tonnes of production in 1997/98.

The project has shown that a virus associated with Mid-Crop Mortality Syndrome is passed from breeders to their progeny. The project has created the knowledge of a detection test and that application of that test can be used by hatcheries to reduce the effect of the virus on productivity in the hatchery and farms.

Identification and management of potential food safety issues in aquaculture-produced yellowtail kingfish (Seriola lalandi)

Hazards such as dioxin (PCDD/F) and PCBs have been identified in manufactured feeds as priorities for further investigation by industry. These issues are now being discussed by the South Australian Marine Finfish Farmers Association Inc (SAMFFA) and Australian feed manufacturers as part of...

Summary

The research programme was largely comprised of farming trials in a 1 ha prawn farming pond and in swimming pools on the pond bank at the field site. Juvenile school prawns (Metapenaeus macleayi) were collected by commercial trawlers in Lake Wolloweyah, transported by punt to the pond where they were stocked and farmed for 2 to 3 months before harvest and marketing at the Sydney Fish Market.

The prawn production results were used as the basis for an independent economic analysis of school prawn farming. The first version of this analysis is discussed in the accompanying NPS2 paper and a revised version presented at the N.S.W. Department of Agriculture Prawn Farming Open Day (a compilation of the papers delivered at this Open Day is attached). Both versions predicted attractive returns on capital but it should be noted that the extrapolation from pilot scale to commercial scale must necessarily be in part hypothetical until it is supported by consistent commercial success.

Summary

This report deals with the period July to October 1977 during which time inspections of the prawn farming industries of Japan, the Philippines and Thailand were made. A total of ten weeks was spent in Japan with shorter periods in the Philippines and Thailand.

Japan not only has the most successful prawn farming industry in the world but its aquaculture research in general is also the most advanced and diverse. Thus it was possible to inspect facilities used for the culture of many species and a brief section dealing with the aquaculture of some of these other species is included, along with observations from the other two countries visited.

The bulk of the report deals with Japanese aquaculture and the aim has been to provide considerable detail but  mostly as a supplement to existing works published in English. Much less published information is available for the aquaculture industries of the Philippines and Thailand and thus the sections relating to these countries are written in as much detail as possible. Some understanding of the larval development of penaeid prawns and portunid crabs is assumed in some sections of this report but not in the general summary (Section 10) which also includes recommendations relevant to the Australian situation.

Summary

Juvenile school prawns (Metapenaeus macleayi) were collected from the Clarence River, N.S.W., Australia and fattened in artificial ponds. After harvest these prawns were assessed by taste panels along with other samples of the same species collected from estuarine fisheries in N.S.W. Taste panels could not detect any significant differences between pond-fat­tened and wild prawns and both were found to be highly acceptable.
