This report provides the most comprehensive appraisal of the risk posed by bycatch to subpopulations of Australian sea lions and New Zealand fur seals, by the SA rock lobster and gillnet sector SESSF fisheries. Further it has identified the research required to ensure that SA rock lobster and the gillnet sector SESSF fisheries are managed according to ESD principles, and that interactions with seals are measured, assessed and mitigated. Adoption of these recommendations will lead to the development, and adoption by industry and management of mitigation options to reduce seal bycatch. This will ensure that outstanding ESD recommendations detailed in fishery ESD assessments and the mitigation of the key threatening process identified in the Australian sea lion Draft Recovery Plan are addressed, leading to the recovery and potential future delisting of the species.

Objectives

1. Synthesise and review the PIRSA and AFMA fishery logbooks for the SA Rock Lobster and Commonwealth shark fisheries for reportings of interactions with seals.

2. Undertake a desktop risk assessment of seal-fishery interactions in the SA Rock lobster and Commonwealth shark fisheries, based on distribution of catch and effort in proximity to seal populations.

3. Review the managment responses related to the extent of protected species interactions with similar species and fisheries on a global scale.

4. Develop a proposal for a comprehensive study to assess the level and nature of interactions between seals and the SA Rock Lobster and Commonwealth shark fisheries, including the development of guidelines for measuring the performance of systems for monitoring, assessing and mitigating interactions between the fisheries and seals.
