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...

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...

Enhancement of yabbie production from Western Australian farm dams

Farmers receive higher prices per kilo for large yabbies. Yabby farmers have reported that the majority of yabbies trapped from farm dams are below market size (< 30 g) and therefore of no economic value. In addition, farmers also report that while dams produce large yabbies when...

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...

Regrowth of pilchard (Sardinops sagax) stocks off southern WA following the mass mortality event of 1998/1999

This project produced time series of estimates of spawning biomass for pilchards in four purse seine management zones in Western Australia, three on the south coast and one on the west coast. The pilchard stocks in Western Australia have recovered strongly since the 1998/99 mass mortality. This...
