Modelling to explore management strategies to optimise the value of the rock lobster fishery of Western Australia

The fishery for the western rock lobster (Panulirus cygnus) is Western Australia’s most important single species fishery, and yields an average annual catch of 10,500 to 11,000 tonnes valued at between $200 and $300 million at the point of landing. With a high level of exploitation and a...

Quantification of changes in recreational catch and effort on inner Shark Bay snapper species following implementation of responsive management measures

A 12-month creel survey of recreational boat-based fishing in Shark Bay, Western Australia was conducted between May 2001 and April 2002 to estimate the catch of pink snapper. During the survey 431 boat crews were interviewed at public boat ramps of which 414 had been fishing. The information...

Management and monitoring of fish spawning aggregations within the West Coast Bio-region of Western Australia

Many strategies have evolved among fishes to maximise spawning success. One of the most striking of these is aggregation spawning, in which individuals group together, often at predictable times and locations in order to reproduce (cf. a school, which refers to a group of non-spawning fish)....

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...
