Abstract

[Extract] Multi-species targeting is a common feature of tropical coastal fisheries and is particularly prevalent in coral reef fisheries such as the Coral Reef Fin Fish Fishery (CRFFF) of the Great Barrier Reef, Queensland, Australia. Predicting the distribution and effects of fishing effort in multi-species fisheries is difficult, and must be factored into management strategies so that all targeted species are adequately protected. In this project, we simulate the targeting behaviour, vessel dynamics and effort distribution in the CRFFF and evaluate alternative management strategies for the sustainable harvest and conservation of the major target species, common Coral Trout (Plectropomus leopardus) and Red Throat Emperor (Lethrinus miniatus). We build on the single species population and effort dynamics models developed for common Coral Trout as part of the previous CRC Reef Research Centre's Effects of Line Fishing (ELF) Project, and extend them to include Red Throat Emperor, the second major target species of the CRFFF, thereby incorporating the multi-species nature of the fishery. We also add an individual-based vessel dynamics model to simulate individual vessel behaviours associated with harvesting the two species. We evaluate simulated outcomes from a range of stakeholder identified management strategies against a range of stakeholder identified management objectives.
