| Description: | Mapping the distribution and movement of gulper sharks, and developing a non-extractive monitoring technique, to mitigate the risk to the species within a multi-sector fishery region off southern and eastern Australia. Objectives 1. In conjunction with SlopeRag, develop criteria and thresholds for monitoring viable populations, particularly in closed areas. 2. Design and implement non-lethal monitoring program (including BRUVS) to identify trends in relative abundance as part of the Conservation Strategies for Harrissons Dogfish and Southern Dogfish. 3. Refine estimates of capture survivoship and release survivorship, particularly for various line fishing methods. 4. Examine the potential of conventional tagging data to calculate biological properties, such as population size, to better inform the management strategy 5. Assess scales and rates of movements outside closed areas using conventional tagging data to better understand edge effects and the role of complimentary mitigation measures to be applied. 6. Establish a science industry partnership for ongoing cost-effective monitoring. |
