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

This project developed and explored methodology intended to enable the production of more reliable estimates of fishing efficiency increases and harvest rate, such that these estimates might be available for use by fisheries scientists, thereby improving the quality of the management decisions...

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...

Spatial scales of exploitation among populations of demersal scalefish: implications for wetline management

West Australian dhufish is endemic to shelf waters of south-western Western Australia (WA). In contrast, snapper (known as "pink snapper" in WA) has a continuous distribution around the southern coastline of mainland Australia and in New Zealand. Dhufish and snapper are the two most important...

Comparing conventional ‘social-based’, and alternative output-based, management models for recreational finfish fisheries using Shark Bay pink snapper as a case study

This study has provided for the first time in Australia, an empirical comparison of different management models with a recreational marine finfish fishery. A TAC-based system was introduced for pink snapper in the inner gulfs of Shark Bay for the first time in 2003-2005, to explicitly manage...

Investigating reproductive biology issues relevant to managing the western rock lobster brood stock

Increases in efficiency due to modem electronic equipment, improved fishing vessels and knowledge about the grounds and lobster behaviour, have all led to western rock lobster fishers becoming more efficient at catching western rock lobsters in Western Australia. One of the outcomes of these...
