Gummy sharks and school sharks are aged by counting growth-increment bands on the articular faces of vertebrae stained with alizarin red. The age data are required for application of age-structured fishery assessment models used by the Southern Shark Fishery Assessment Group for stock advice to the...
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...

Diversity and ecosystem-based indicators were calculated for commercial finfish fisheries from 1976 to 2005 for the West Coast, South Coast, Gascoyne, Pilbara and Kimberley bioregions. The ecosystem-based indices, which detect changes in the species composition of the food web within the ecosystem,...
In order to provide for future growth of the Australian prawn aquaculture industry, there is a need to take a longer-term strategic view and develop production technology for alternative species that can support an export market but do not have the intense overseas competition of the current major...
The aim of this project was to farm, on a pilot commercial scale, two indigenous species of marine fish: snapper, Pagrus auratus; and mulloway, Argyrosomus hololepidotus.
The project involved:
development of hatchery techniques;
intensive rearing of larvae;
transport of live fish;
