Molluscan Fisheries
The Molluscan Fisheries subprogram is focussed on providing scientific advice relevant to the ecologically sustainable management of molluscs in South Australia. Click here to download the Molluscan Subprogram capability statement (.pdf).
Overview
The Molluscan Fisheries subprogram forms part of the Wild Fisheries Science Program Area. The key outputs are scientific papers and stock assessment reports for key species. These reports comprehensively assess all fishery-dependent and fishery-independent data, summarise outputs from risk-analysis models, assess fishery performance against performance indicators defined in management plans and detail resource status. The subprogram also undertakes additional projects and collaborative research that maintain South Australian molluscan research at a world class standard.
Research Projects
FRDC 2008/008 – Harvesting strategy development for South Australia’s Goolwa cockle (Donax deltoides) fishery.
FRDC 2004/019 – Towards optimising the spatial scale of abalone fishery management.
