- To use the EASI-Fish ERA approach to assess vulnerability status and the efficacy of conservation and management measures prescribed under IATTC Resolution C-19-04 for reducing fishing impacts on the East Pacific stock of leatherback turtle (Dermochelys coriacea).
- IATTC is committed, through the Antigua Convention, to ensure the long-term sustainability of all non-target species impacted by EPO tuna fisheries.
- On 1 January 2021 a revised resolution on sea turtles (C-19-04) entered into force that requires EPO tuna fisheries to implement various measures designed to reduce the bycatch of sea turtles, in particular the use of circle hooks and finfish baits in shallow longline sets.
- EASI-Fish has been used by the IATTC as an alternative approach to traditional population models to assess the efficacy of management measures on data-limited bycatch species, including the critically endangered spinetail devil ray.
- In collaboration with the Inter-American Convention on the Protection and Conservation of Sea Turtles (IAC) and EPO stakeholders, the staff developed a preliminary EASI-Fish assessment for 2018. The project was extended to improve on this model through the development of a dedicated species distribution model and an update of the fishing effort by coastal artisanal fisheries.
- Importancia para la ordenación
- EASI-Fish can rapidly and cost-effectively quantify the cumulative impacts of multiple data-limited fisheries on species under proposed management measures—either individually or in combinations—under IATTC Resolution C-19-04 to determine their potential efficacy of reducing the vulnerability of the EP leatherback turtle stock to becoming unsustainable in the long-term. This will ultimately simplify the choice of management measures required to meet conservation and fisheries objectives.
- 12 months
- Plan de trabajo y estatus
- Jun-Sept 21: Collaborate with stakeholders to collate available fishing effort and leatherback presence data in the EPO.
- Sept 21-Jan 22: Develop a new approach to use presence and absence records to produce a dedicated species distribution model (SDM) for the East Pacific leatherback turtle stock.
- Jan 22-Apr 22: Populate EASI-Fish model with biological and fisheries data and run 70 hypothetical scenarios
- May 22: Present final EASI-Fish assessment results and the special distribution model to the Bycatch Working Group (BYC-11).
