AgENCy PERFORMANCE � SERvICE 3 – RESEARCH AND MONI<strong>TO</strong>RINg • Undertaking monitoring and research activities aimed at limiting the potential introduction and impact of marine pest species. • Investigation of the effects of fishing on stocks, habitats, bycatch species, protected species and the ecosystem in general. • Undertaking research and development activities to assist with the expansion of the State’s aquaculture industry. Significant scientific advice and contributions are also provided by the Research Division to assist the Department of Fisheries in: • Negotiating management or governance arrangements with Commonwealth agencies (such as the Department of Sustainability, Environment, Water, Populations and Communities (SEWPaC); the Department of Agriculture, Fisheries and Forestry (DAFF); and the Australian Fisheries Management Authority (AFMA)). • Providing advice to support the development of national and international strategies. • Providing advice on risks and impacts of marine and coastal developments including those associated with the resources sector. • Information to support Wildlife Trade Operation accreditation by State fisheries to obtain export approvals under the Commonwealth’s Environment Protection and Biodiversity Conservation Act 1999. The individual branches of the Research Division and their work are described below. Invertebrate fisheries 91 The Invertebrate Fisheries Branch undertakes research to assess and monitor the crustacean and mollusc stocks that support the State’s major fisheries, which include rock lobsters, prawns, pearl oysters, scallops, abalone and crabs. A focus of research in recent years has been the development of estimates of pre-recruitment abundance to make catch predictions and then using these predictions in the management of the fisheries through management ‘decision rules’. The Invertebrate Fisheries Branch also assists the Biodiversity and Biosecurity Branch to undertake research on broader ecosystem-related issues associated with these fisheries, such as bycatch and community structure, including a number of collaborative projects with universities, the Western Australian Museum and the Commonwealth Scientific and Industrial Research Organisation (CSIRO). The Invertebrate Fisheries Branch is also responsible for staffing and programming the Department’s major research vessel, the RV Naturaliste. This vessel undertakes a range of research activities throughout the year, encompassing trawling, fish trapping, rock lobster fishing, longlining, biodiversity studies and environmental monitoring.
AgENCy PERFORMANCE � SERvICE 3 – RESEARCH AND MONI<strong>TO</strong>RINg finfish fisheries The Finfish Fisheries Branch undertakes research to assess and monitor the State’s diverse finfish resources. The branch monitors indicator species for finfish resources in all the biogeographical regions that Western Australia has been practically divided into by the Department of Fisheries. Some of the species monitored include Western Australian dhufish, temperate snapper and baldchin groper, which are indicator species for the health of the west coast demersal scalefish resource. Other indicator species monitored and assessed include tropical shallow-water and deepwater snappers, sharks, nearshore species such as Australian herring and estuarine species such as cobbler. These species are harvested by commercial fishers (supplying local and overseas markets), the recreational fishing sector (involving around 600,000 fishers) and the managed recreational charter fishing sector. Much of this research work also relates to the species and stocks that are the focus of the Department of Fisheries’ Integrated Fisheries Management strategy. The Finfish Fisheries Branch also supports a significant number of collaborative research projects at local universities and other research groups (Australian Institute of Marine Science, CSIRO) many of which involve postgraduate research students. Biodiversity and Biosecurity The Biodiversity and Biosecurity Branch has statewide responsibilities for the provision of scientific advice relating to the conservation of fish and invertebrates and protection of the environment. This includes responsibility for issues such as: • Health of benthic habitats including faunal (coral) and floral (seagrass) components. • Biosecurity issues. • Provision of fish pathology services. • Freshwater research (e.g. native fish conservation). 92 • Production of trout and native fish species at the Pemberton hatchery and the Shenton Park research facility. • Management of the Department’s marine aquarium facilities. The work of the Biodiversity and Biosecurity Branch is carried out in collaboration with the Department’s Aquatic Management Division, the Department of Environment and Conservation, various universities, the Australian Institute of Marine Science, natural resource management groups, and port and harbour authorities. Stock Assessment and data Analysis The Stock Assessment and Data Analysis Branch provides support for the Research Division and the Aquatic Management Division in the fields of
