Analysis of fish pricing in New South Wales: relationships between prices at auction and retail and between prices at Sydney and regional centres

In this Miscellaneous Bulletin a research project funded by the Fishing Industry Research Committee is reported. The aim of this project was to derive price spreads for the major fish species marketed in Sydney. Weekly auction-retail price spreads for fifteen categories of fish and two categories 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.

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...

Evaluation of hatchery production of scallop Pecten fumatas

This project was prompted by poor or variable availability of wild commercial scallop spat for fisheries enhancement and farming in southern Australia and by generally poor and variable success of commercial oyster hatcheries in earlier attempts to fill this shortfall. Scallops from Jervis Bay,...

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...

A preliminary assessment of the rock lobster fishery in New South Wales

The objectives of this study were to determine whether catch rates of rock lobsters in the commercial fishery off New South Wales were declining, the size and species composition of catches from the commercial fishery and to ascertain the smallest length at which 50% of female eastern rock lobsters,...
