SPECIES
The need for special research projects and individual stock assessments is detailed by the South East Fishery Assessment Group (SEFAG) and endorsed by SETMAC. The development of stock assessments for blue grenadier, and ling are high priority. Other species with high priority for quality stock assessment include blue warehou, redfish, blue-eye trevalla, and (following SETMAC 55) tiger flathead.
Blue grenadier is a species for which new data have become (or are becoming) available and for which there is a conflict between the relatively optimistic scientific advice (based primarily on an acoustic and an egg production estimate) and the more pessimistic view of several industry representatives. The stock assessment for this species will be accorded first priority. The other two species to be assessed wil be determined based on discussions with SETMAC, its research sub-committee and AFMA.
1. Provide high quality population dynamics models and stock assessment advice for three SEF quota species for which there is immediate concern of stock status.
2. Work with industry and managers in developing population dynamics models in a manner that will improve the stock assessment in the SEF and its perception by industry.
3. Use the stock assessments to evaluate stock status against current management performance indicators and to provide advice on alternative performance indicators if necessary.
4. Evaluate the value (in terms of improved assessement) of future data collections and research studies for the assessed species.

NCCP: Population dynamics and Carp biomass estimates
This study was undertaken by the Arthur Rylah Institute for the Department of Environment, Land, Water and Planning. Carp (Cyprinus carpio) is Australia’s most invasive pest fish. To facilitate more effective management, the Australian Government is considering release of a Carp herpesvirus...

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.

Population dynamics and management of spanner crabs in southern Queensland
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...
