Project start/end date: 27 Jun 1996 - 13 Sep 2000
1. To assess the size and age at maturity and reproductive capacity of rankin cod, and lesser spangled emperor, the two species for which no information is available elsewhere.
2. To develop a more cost effective and accurate method of monitoring the level and distribution of catch and effort of the ten most valuable species.
3. To investigate fish movement patterns, and the periodicity of otolith growth rings by tagging key species and monitoring tag returns.
4. To use the age structure of the 5 key species over time to assist in the evaluation of the effectiveness of management strategies.
5. To confirm that otolith growth rings are annual for the five key species, using marginal increment analysis.
6. To refine and improve modeling techniques using biological, ageing, and tagging information.
