Stock identity of northern fish species

The research program supported by this grant was directed at determining the number and distribution of subpopulations or genetic stocks which contribute to Australian fisheries for barramundi, northern sharks, and narrow-barred Spanish mackerel. Starch gel electrophoresis was used to reveal...

Recruitment processes in commercially important prawn species

The following report is a description of the two FIR TA 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...

Objectives

1. To determine the number and locations of spawning grounds for the major commercial finfish species in temperate Australian waters.
2. To examine patterns of larval drift for indications of the distribution and number of nursery grounds for these species.
3. To apply microprobe and genetic techniques to larvae juveniles and adults to quantify the spread of individuals from spawning and nursery areas and the mixing of stocks.
4. To use these data to infer the stock structure of temperate Australian finfishes.

Fisheries biology of deep-water crustacea and fin fish on the continental slope of Western Australia

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...
