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...
