1. To obtain data (catch and effort, tagging, sampling) and analyse it to gain estimates of growth, mortality, catchability, female size at maturity, lenght-weight and movement
2. To develop an age structured population dynamics model of the fishery that will allow discrimination at the zone adn smaller spatial scale
3. To use the model to identify the most important biological parameters so as to give them highest priority
4. To use the model to estimate sustainable yields, predict outcomes of alternative management strategies and understand the interactions of the two management zones
5. To provide an accessible, secure data base of stock information, improved data validation and verification.
6. To provide a graphics interface for the models and ata to facilitate understanding by industry and management
7. To transfer results to industry and other user groups
8. To involve industry in research and educate them about the results and their consequences
9. To obtain preliminary habitat and oceanographic information to assist in determining critical habitats and physical processes controlling rock lobster distribution and abundance.

This study looks at the population dynamics and fishery biology of the southern rock lobster, Jasus edwasrdsii, in South Australian waters. The four distinct areas of investigation are biological research to describe key population parameters; development of a comprehensive database of biological and fisheries data; integration of biological and fisheries parameters and data in a computer simulation model of the lobster stock and fishery, and dissemination of the project results and assisting commercial fishers to use the simulation model and other information generated by the project.
