Effects of Trawling Subprogram: assessment of bycatch in the Great Australian Bight Trawl Fishery
Principal Investigator: Ian A. Knuckey and Lauren P. Brown
1. Design an onboard sampling strategy which will provide a representative sample of the spatial and temporal dynamics of the total catch composition (retained and discarded) in the GABTF.
2. Undertake onboard sampling of commercial vessels and collect basic biological data (size, growth, age, maturity etc.) on the important species caught in the GABTF.
3. Based on the data collected during this project, provide Industry, the GABMAC and stock assessment scientists with information on GABTF species biology and bycatch composition appropriate to their specific needs.
4. Investigate the potential for Environment Australia to fund data collection from commercial vessels working within the GAB Marine Park which can be used in conjunction with or comparison to the CSIRO research cruise. (To be negotiated)
