- To use the EASI-Fish ERA approach to assess the vulnerability status of elasmobranch species caught as bycatch in EPO fisheries
- To identify vulnerable species using traditional biological reference points
- IATTC is committed, through the Antigua Convention, to ensure the long-term sustainability of all non-target species impacted by EPO tuna fisheries.
- Elasmobranchs have been identified in previous qualitative ERAs to be among the most vulnerable species to tuna fishery impacts in the EPO. However, these species lack sufficient biological and catch data for stock assessment, so data-limited approaches are required to assess vulnerability.
- In 2019, the IATTC developed EASI-Fish (Ecological Assessment for the Sustainable Impacts of Fisheries) to quantitatively assess vulnerability using traditional biological reference points used in fisheries stock assessment (e.g. FMSY, SPR20%).
- Relevance for management
- The EASI-Fish assessment will transparently identify vulnerable elasmobranch species in the EPO (and across the Pacific where applicable). Vulnerable species can then be subjected to further assessment where managers can be advised on the efficacy of potential conservation and management measures that may be implemented to reduce vulnerability to sustainable levels.
