  • You can use the Project Search Tool below to browse over the staff’s research projects, including their brief summaries, that are currently under way, or planned for the near future and funded under the 5-year Strategic Science Plan (2019-2023). The summaries include, for each project, background information, a work plan, and a progress report, as well as details of its relevance and purpose, external collaborators, duration, and deliverables; also, for existing projects, an update on activities since the previous year’s report.

    This information can also be found on the IATTC-98b-Staff activities and research plan.

    01 Apr 2020 - 31 Dec 2021
    Funded
    Objectives:
    Conduct Phase 1 (1st year) of a long-term sampling program of shark catches by artisanal fisheries in Central America, using sampling methods and logistics developed under the extended FAO-GEF project.
    01 Apr 2023 - 31 Mar 2026
    Funded
    Objectives:
    Contribute towards the development and implementation of a regional shark fishery sampling program in the EPO, providing data for several types of stock assessments at IATTC (e.g. data-limited assessments, Close Kin Mark Recapture assessments, and conventional assessments).
    01 Mar 2022 - 01 Mar 2023
    Funded
    Objectives:
    Evaluate the suitability of different technologies to remotely and electronically identify FADs
    01 Jan 2018 - 31 Mar 2021
    Funded
    Objectives:
    A proof-of-concept study to evaluate the types of data that can be reliably collected by electronic monitoring (EM) on Class 1-5 purse-seine vessels.
    01 Nov 2017 - 01 Nov 2019
    Funded
    Objectives:
    Evaluate the potential improvement in accuracy of the growth model for bigeye in the EPO resulting from including more age-at-size data for large fish
    01 Jun 2017 - 31 May 2022
    Funded
    Objectives:
    Estimate age, growth, maturity, and fecundity of yellowfin from four distinct areas of the eastern Pacific for use in spatially-structured stock assessment models
    23 Jan 2019 - 25 Jan 2019
    Funded
    Objectives:
    Resolve concerns about differences in age estimation methods and resulting growth models used in bigeye tuna stock assessments by IATTC and WCPFC
    01 Jan 2020 - 31 Dec 2021
    Funded
    Objectives:
    Evaluate geographic variation in movements, behavior, and habitat utilization of yellowfin tuna via analyses of existing archival tag data sets from several discrete areas of the EPO
    01 Jan 2019 - 31 Dec 2023
    Funded
    Objectives:
    • 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
    01 Jan 2017 - 31 Dec 2020
    Funded
    Objectives:
    Determine whether bigeye and skipjack tuna from discrete areas of the Pacific Ocean show significant genetic heterogeneity
