Rock Lobster Enhancement and Aquaculture Subprogram: the feasibility of translocating rock lobsters in Tasmania for increasing yield
University of Tasmania (UTAS)
Modelling of the Tasmanian lobster resource has indicated that loss of yield through spatial differences in growth of lobsters is greater than 25% of the TACC. Effects of fishing on egg production/recruitment and ecology also appear poorly managed spatially. Increasing catch targets high priority areas in the strategic plans of each stakeholder. The Tasmanian Government has stated their intent to pursue growth in primary industry as a key strategic area through the “State of Growth” strategy. The project squarely targets all aspects of the University of Tasmania's “EDGE agenda”, particularly through “Engagement” with the community by delivery of a substantial economic benefit. The need for this research has been identified by the commercial and recreational lobster sectors in each strategic plan for crustacean research since the first plan was produced by the CRAG in 1996, specifically under the topics of “stock enhancement” and “translocation”.
1. To determine the costs associated with translocation lobsters.
2. To model the economic outcomes of translocation based on available biological data.
3. To combine the cost and economic outcomes into a bio-economic model.
4. To model the economic viability of large scale translocation operations to achieve yield increases.
5. To identify crucial input data that impact on the economic viability of translocation.
6. To identify further data requirements from field experiments.
7. To evaluate cost recovery options for a long term operational system for translocation.
