Minimising the cost of future stock monitoring, and assessment of the potential for increased yields from the oceanic snapper, Pagrus auratus, stock off Shark Bay

The investment in this project has resulted in a substantially more extensive set of age composition data than would have otherwise been possible. This in turn has underpinned stock assessment modeling that has provided the basis for determining that the commercial fishery for snapper in Shark...

Studies on the breeding stock of the western rock lobster (Panulurus cygnus), in relation to stock and recruitment

Studies on the breeding stock of the western rock lobster, Panulirus Cygnus George, were conducted to examine the appropriateness of the current measure of the abundance of the breeding stock. Research cruises, commercial monitoring and laboratory studies were undertaken between 1984 and 1988. Data...

Demersal finfish resource assessment survey of the north-west slope of Western Australia

The nature and extent of demersal finfish resources in deep slope waters (>200m) off the northwest coast of Western Australia are poorly understood. Existing fish trawl, trap and line fishing effort is concentrated in shallower waters (<200m), while trawling in deep slope waters...

Mortality, growth and movements of the western rock lobster, Panulirus cygnus

The very high levels of exploitation in the western rock lobster fishery have resulted in the introduction of regional or zone-specific management arrangements in recent years. This is a permanent departure from an holistic approach to the fishery’s regulation. A detailed knowledge of...

Mitigation measures to reduce entanglements of migrating whales with commercial fishing gear

This project provided a robust assessment that gear modifications introduced into the WCRLMF and octopus fisheries have reduced the number of reported entanglements. The management arrangements around the implementation of these modifications are appropriate in light on the new spatial and temporal...

Fishery independent study of the spawning stock of the western rock lobster

The fishery for western lobster (Panulirus cygnus) has supported an annual catch of about 10 500 tonnes per annum over the last twenty years and is worth between $200-300 million per annum. The fishery has been experiencing increasing exploitation rates over time and estimates in the...

Environmentally sustainable development of barramundi cage aquaculture

A preliminary sensory evaluation study was conducted to confirm the presence of a taint issue. Prior to this the issue was reliant on purchaser feedback and was not verified independently. To examine the issue of flavour taint a series of barramundi samples were collected from Lake Argyle (purged...
