- Obtain data that will contribute to, and reduce uncertainty in, EPO tuna stock assessments, particularly for skipjack tuna;
- Obtain information on the rates of movement, dispersion, and mixing of skipjack, yellowfin, and bigeye tunas in the EPO, and between this region and other adjacent regions of the Pacific basin; and
- Obtain estimates of sex-specific growth, mortality, abundance, selectivity, and exploitation rates for those species of tuna in the EPO
- This project is described in detail in Appendix 2 of Document CAF-05-04, prepared for the meeting of the Committee on Administration and Finance in July 2017
- 5 years (2019-2023)
- Workplan and status
- Phase 2 of the IATTC multi-year regional tuna tagging project will consist of two tagging cruises conducted during 2020 and 2022 of approximately 90 days each.
- A pole-and-line live-bait tuna fishing vessel has been chartered to conduct a tuna tagging cruise during the period of February through April of 2020.
- Permits have been obtained from the Government of Ecuador and the Galapagos National Park, as well as the Government of Panama, and the Government of Mexico and the Revillagigedo Islands National Park for catching bait and fishing/tagging tunas during the 2020 tagging cruise period.
- The 2020 cruise plan included going directly from the vessel’s homeport of San Diego to the Galapagos Islands to begin fishing/tagging operations, focusing on SKJ.
- The 2022 cruise plan is modified from 2020 as it was deemed catching bait within the Galapagos National Park wasn’t possible in sufficient quantities to justify returning.
