Northern shark tagging study

In 1982, CSIRO applied to the Fishing Industry Research Trust Account for funding of a joint biological investigation of northern Australian pelagic fish stocks. At that time these stocks supported a Taiwanese surface gill-net fishery based on sharks, tunas and Spanish mackerel. During the 1970's...

Tide and current analysis of the Gulf of Carpentaria and its relation to banana prawn larval dispersion

The prawn fishing industry in the Gulf of Carpentaria is worth $100 million/year and a large proportion of this is from catches of banana prawns. In one stage of their complex life history, banana prawn larvae are carried by ocean currents from their spawning grounds to the estuarine nursery...

Second Australian National Prawn Seminar

Since the First Australian National Prawn Seminar in 1973, Australian prawn fisheries have grown in size and value to become Australia's most valuable fisheries resource. In the same period the number of people involved in the fishing industry, research and management has also increased. Major new...

Evaluation of harvesting strategies for Australian fisheries at different levels of risk from economic collapse

Management of a marine renewable resource involves selecting a trade-off between conflicting objectives related to conservation and utilization. This problem is complicated by uncertainty about the current status and productivity of the resource being managed, and hence about the implications of...

Causes of decline in stocks of commercially important prawns in the Northern Prawn Fishery

The following report is a description of the two FIRTA projects (85/85 & 89/13) which examined recruitment processes in penaeids at Albatross Bay in the northeastern Gulf of Carpentaria over the years 1985 to 1992. The aim of the first of the two projects was to identify the main factors which...

Summary

This project sought to investigate the population biology of the commercially important species, primarily crustaceans and finfish, caught in the North West Slope Trawl Fishery (NWSTF) and Western Deep Water Trawl Fishery (WDWTF).

This work aimed to measure standing stocks, growth rates, natural mortality rates, and reproductive periodicity, to enable estimation of potential yields from the fishery.

The logbook program and database, for the collection, storage and retrieval of information on catches by commercial vessels, was completed as planned.
