Offshore Crustaceans
The Offshore Crustacean Subprogram provides PIRSA fisheries with all scientific advice relevant to the sustainable management of both the southern rock lobster (Jasus edwardsii) and giant crab (Pseudocarcinus gigas) fisheries in South Australia. Annual stock assessment reports detail resource status and assess fishery performance against the performance indicators defined in the Management Plan for each resource.

Overview
The subprogram is lead by Dr. Adrian Linnane. Research involves analysis of data from logbooks, voluntary catch sampling, puerulus monitoring and fishery-independent surveys. Specific research projects that address the ecologically sustainable utilisation of the rock lobster and giant crab resources are also undertaken. These include periodic bycatch surveys and research into the development of mitigation devices aimed at reducing interactions with threatened/endangered marine species. The primary outputs are stock assessment reports that provide the scientific basis for sustainable fisheries management. Scientific findings are published in peer-reviewed reports, and national and international journals.
