Objectives

1. To investigate species composition of blue-eye in southern Australian waters through a detailed morphological and genetic comparisons of two identifiable morphs, and, if two species do exist, to prepare guideline information on their spatial and geographic distributions.
2. To assess stock structure and to determine the approximate extent of gene flow among populations taken from different area of southern Australia.

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...

Development and use of the egg production method to assess the biomass of orange roughy off eastern Tas

Orange roughy is one of Australia's most valuable finfish However, its aggregating behaviour during spawning, slow growth, and longevity render it vulnerable to over-exploitation. Some stocks in New Zealand are at extremely low levels after only ten years of exploitation. Good management is vital...

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...
