Determination of the diets of Snapper and Silver Trevally and construction of a food web for the demersal fish community in south-western Australia

The focus of the fishery studies in Node 4 of the WA Marine Science Institute is the development of ecosystem-based fishery management for the State's fisheries. This has led to exploration of the methods by which the ecosystem effects of fishing may be monitored and assessed, and an evaluation of...

Population biology of albacore tuna in the Australian region

The catch of albacore in the ETBF increased from ~500 tonnes per year in the late-1990s and early-2000s, to 2,591 tonnes in 2006 as a number of domestic longliners switched from targeting broadbill swordfish (shallow setting) to albacore tuna (deep setting). In 2007, this higher catch was maintained...

Identifying factors affecting the low western rock lobster puerulus settlement in recent years

The low puerulus settlement in 2006/07, 2007/08 and 2008/09 (preliminary) has been the initial impetus to developing this project. This project is complementary to the FRDC tactical research funding application to be submitted for the 1 November 2008 to urgently examine the oceanographic modelling...

Evaluating the potential use of change-in-ratio and index removal techniques for determining harvest rates and efficiency increases in the Western Rock Lobster Fishery

The sustainable management of an input controlled fishery, such as that for western rock lobster, which is controlled via a total allowable level of effort (TAE), relies heavily on accurate measurement of relative effort. The number of potlifts used by fishers, which is a direct measure of effort,...

Evaluation of population genetic structure in the western rock lobster

The western rock lobster fishery began in the 1940s and has since grown to become the most valuable single species caught in Australia. Over the last 20 years the annual catch has averaged approximately 10,000 tonnes, varying between 8,000 and 14,000 tonnes per year due to natural variations in the...

Movement patterns and stock structure of Australian sardine (Sardinops sagax) off South Australia and the East Coast: implications for future stock assessment and management

The Australian sardine (Sardinops sagax) is distributed throughout southern Australia, between Shark Bay, WA and Hervey Bay, Qld. There are commercial fisheries in waters off WA, Vic, SA and NSW. Two fisheries for Australian sardine have grown rapidly over the last decade. The current Total...

Tactical Research Fund: industry monitoring and sampling of Gulper shark catches in the SESSF

Gulper sharks (Centrophorus species) are caught as bycatch by Gillnet, Hook and Trap, Commonwealth Trawl and Great Australian Bight Trawl sectors of the Southern and Eastern Scalefish and Shark Fishery. Recently completed ecological risk assessments of these fisheries identified upper-slope gulper...

Mapping the distribution and movement of gulper sharks, and developing a non-extractive monitoring technique, to mitigate the risk to the species within a multi-sector fishery region off southern and eastern Australia

Gulper sharks (Centrophorus) are species of deepwater dogfish that occupy the upper slope and some offshore seamounts around southern and eastern Australia. This group represents one of the most urgent environmental challenges to the SESS fishery, and may even threaten its "license to operate"....

Ecological risk assessment for effects of fishing on habitats and communities

This application builds on the Ecological Risk Assessment for the Effects of Fishing (ERAEF) project which provides a hierarchical risk assessment approach to assist fisheries to understand and respond to their ecological risks, in particular to satisfy requirements under the EPBC Act. The...

Taking female mud crabs (Scylla serrata): assessment of risks and benefits

This project has been developed as a direct result of approaches from industry about the need for a definitive answer to questions relating to one of the State's most controversial crab fishery management arrangements. An effective prohibition on harvesting female mud crabs in Queensland was...
