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.
1. To promote the opportunity during the Australian Society for Fish Biology annual conference for the national fisheries research expertise to focus on a technical area or subject of current or percieved national or regional fisheries significance.
2. To promote the opportunity during the Australian Society for Fish Biology annual conference for the national fisheries research expertise to focus on a technical area or subject of current or percieved national or regional fisheries significance.
3. To assist in the publication of workshop proceedings as a benchmark document of current knowledge in the workshop subject area
4. As a result, to identify, and define research questions of national fisheries significance.
5. The proposed workshop - "Population Dynamics for Fisheries Management" - will focus on what are the processes leading to the development of management advice

Spanner crabs (Ranina ranina) represent a valuable resource to southern Queensland and northern NSW. The fishery became established in the late 1970s, and as a result of an almost exponential increase in fishing effort between 1992 and 1995 an output-controlled limited entry management arrangement...
