Understanding the factors contributing to decreased school prawn productivity in Camden Haven Estuary and associated lakes, to target ameliorative actions

New South Wales Department of Primary Industries (NSW DPI) presents new information exploring the effect of catchment-derived stressors on Eastern School Prawn. Declines in School Prawn productivity over decadal time scales have been reported anecdotally across many estuaries in New South Wales, and...

The impact of habitat loss and rehabilitation on recruitment to the NSW eastern king prawn fishery

New South Wales Department of Primary Industries (NSW DPI) presents new information exploring the linkages between estuarine habitats and exploited species. Establishing linkages between fisheries and the habitats that support them is essential to the effective management and repair of marine and...

Red spot disease of sea mullet (Mugil cephalus)

Results of a previous FIRTA-funded project (86/53) indicated that red spot disease (RSD), a cutaneous ulcerative disease of estuarine fish, is caused by a number of interacting factors. The study showed that lower catchment rainfall is an important determinant of RSD outbreak occurrence. The study...

Review of shellfish purification technology research and development

Depuration in the context of this report can be defined as the process by which harvested shellfish are placed in land based plants containing clean estuarine water to permit the purging of their gastrointestinal contents under controlled conditions. Depuration does not include the practice of...

Coastal floodplain management in eastern Australia: barriers to fish and invertebrate recruitment in acid sulphate soil catchments

Estuarine habitats, and in particular coastal floodplains and wetlands, provide essential nursery habitat for a large number of fish and prawn species, many of which are commercially and recreationally significant. Human activities on coastal land, such as those associated with grazing and...

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.

Strategic Plan for Research and Development of the Oyster Industry in NSW

The NSW oyster industry is one of the states oldest and most valuable fishery, with a farm gate value of more than $27 million in 1994/ 5. It has an impressive history covering more than a hundred years of farming the native Sydney rock oyster Saccostrea commercialis but has experienced a decline...

Spatial management within the NSW Ocean Trawl Fishery

The NSW Department of Primary Industries-Fisheries has outlined the results of a four-year trawl survey (2017-2020) aimed at evaluating spatial management provisions within the NSW Ocean Trawl Fishery (OTF) and the potential for these to be adapted to deal with tactical challenges associated with...
