- To use the EASI-Fish ERA approach to assess the efficacy of potential conservation and management measures for reducing fishing impacts on shark species identified in project L.2.b as being highly vulnerable in the EPO
- IATTC is committed, through the Antigua Convention, to ensure the long-term sustainability of all non-target species impacted by EPO tuna fisheries.
- IATTC Project L.2.b used the EASI-Fish (Ecological Assessment for the Sustainable Impacts of Fisheries) approach to identify the most vulnerable elasmobranch species caught as bycatch in EPO tuna fisheries.
- 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 leatherback turtle and the spinetail devil ray.
- The staff has been tasked to conduct conventional stock assessments for priority shark species, but the quality of the available fishery data remains prohibitive for this purpose (see section 4 on shark workplan). As an interim data-limited alternative to conventional stock assessments, EASI-Fish will be used to assess shark species identified as being highly vulnerable.
- Importancia para la ordenación
- EASI-Fish assessments can transparently identify vulnerable elasmobranch species in the EPO. However, vulnerability may be reduced differently for each species. Therefore, by undertaking separate EASI-Fish assessments for each vulnerable species, management measures that may be most efficient and cost-effective may be identified for each species, and for all species in concert. This will ultimately simplify the development of fewer management measures (if required) and minimize the losses of target species catch as a result.
