Objectives

1. Determine the key population parameters (age validation, growth, age of maturity, mortality of fished cohorts, and population structure after age validation), distribution, movements and relative abundance of the Patagonian toothfish around Macquarie Island.

2. Assess the usefulness of DNA micro satellite markers for determining stock structure.

3. Assess the biological and physical oceanographic effects on catch rates, toothfish availability, and interactions between the fishery and non-target species.

4. Assess the magnitude and composition of the fishery bycatch, and identify the food chain linkages between the fishery, the toothfish, the main bird and mammal species.

5. Develop population models for the Patagonian toothfish fishery and provide strategies for developing and managing the fishery.
