Completion of an analysis of stock structure of orange roughy, based on otolith chemical composition

Project number: 1996-111
Project Status:
Completed
Budget expenditure: $86,605.00
Principal Investigator: Ronald E. Thresher
Organisation: CSIRO Oceans and Atmosphere Hobart
Project start/end date: 8 Aug 1996 - 11 Aug 1999
Contact:
FRDC

Objectives

1. To complete a statistically valid evaluation of the stock structure of orange roughy in southern Australia, based on regional difference in otolith composition, by increasing sample sizes and coverage beyod that undertaken in a pilot study
2. To provide the results of analysis to industry, SETMAC and AFMA, for incorporation in management plans for the orange roughy fishery
3. To asses the utility of the otolith-based technique for other deepwater fished species such as oreo dories

South Australian deep water line fishing developments

During November and December 1983 and February to May 1984, the Commonwealth funded South Australian Deep Water Line Fishing Survey investigated the viability of droplining and trotlining on the continental slope off southeast Australia. At present many south Australian fishermen rely heavily on...

Long-term analysis of the sea-state in the Great Australian Bight

This report provides a detailed characterisation, assessment and prediction of the meteorological and oceanographic conditions that will be encountered by, and have the potential to impact, future petroleum activities in the Great Australian Bight. In the absence of direct, long-term...

Application of satellite real-time sea surface temperature data to the tuna, salmon and pilchard fisheries

This is the final report for FIRTA project 1981-056. The principal objective has been to study the application of real-time satellite-derived sea surface temperature measurements in assisting particular fisheries located in southern waters of Australia. Initially proposed for a three year period...

Summary

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 areas.

The aim of this project was to define the currents that carry the larvae so that the life history can be more fully understood and various biological hypothesis concerning the banana prawn and in particular the behaviour of larvae can be fully tested. To achieve these goals a mixture of field work and theoretical modelling and cooperation between physical oceanographers and fisheries biologists was required.
