In situ time-stamping of abalone shells to determine how abalone stocks can be aged.

If abalone can be accurately aged, this would be a fundamental tool for more effective management of abalone fisheries. Several authors have proposed ageing abalone by grinding or cutting abalone shells, and counting the shell layers deposited beneath the spire. Other authors have cast...

Objectives

1. To carry out a literature search on pilchards and other small pelagic fish species
2. To describe the main bait fisheries including catches, areas and by-catch species
3. To determine the stock structure of the main bait species in east and SE Australia
4. To describe the biology of pilchards in Australia, including age, growth, reproductive cycles and fecundity
5. To evaluate the potential of using egg surveys to estimate spawning biomass of pilchards in SE Australia
6. To estimate the potential yields of pilchards in SE Australia

Summary

This project was initiated in response to a rapid increase in the demand for pilchards and other baitfish species and the subsequent expansion of purse-seine fisheries throughout southeastern Australia. During the course of the proj ect, the need for research on pilchard stocks was further increased by the mass mortality of adult pilchards that occurred between Noosa Heads (Queensland) and Red Bluff (Western Australia) in autumn 1 995 and the decrease in the 1 997 Total Allowable Catch for the Western Australian pilchard fishery which lead to a shortage of pilchards on Australian markets.

Spawning and reproductive characteristics of Bight redfish and deepwater flathead in the Great Australian Bight trawl fishery

This project addressed some of the important information gaps identified during assessment workshops for Bight redfish and deepwater flathead. Improved stock assessments, which incorporate the latest biological parameters (size-at-maturity, fecundity and sex ratio), has lead to the setting of...
