  • 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.

    15 Jun 2018 - 15 Jun 2019
    Funded
    Objectives:
    Assess the spawning ecology of captive yellowfin tuna at the Achotines Laboratory, by estimating the number of females that contribute to single spawning events, and their spawning periodicity and frequency
    01 Jan 2020 - 31 Dec 2021
    Funded
    Objectives:
    Evaluate movements, behavior, and habitat utilization of silky sharks in the equatorial and tropical EPO from in-depth analyses of existing data obtained from archival tags
    01 Jul 2022 - 01 Jul 2024
    Funded
    Objectives:
    To obtain morphometric relationships for priority species (e.g., tunas, billfishes, elasmobranchs, other large fishes) and to opportunistically collect biological samples
    01 Jan 2018 - 31 Dec 2023
    Funded
    Objectives:
    Investigate the effects of key biological and physical factors on the survival and growth of pre-recruit life stages of yellowfin, with a new emphasis on studies of early-juvenile life stages
    01 Jun 2018 - 31 Dec 2023
    Funded
    Objectives:
    Investigate important comparative aspects of the reproductive biology, genetics and early life histories of yellowfin and Pacific bluefin tuna
    01 Jun 2018 - 01 Jun 2024
    Objectives:
    To develop a larval or early-juvenile growth index for yellowfin tuna in the Panama Bight which might prove useful as an index of recruitment strength of yellowfin in the EPO
    01 Jan 2018 - 31 Dec 2020
    Funded
    Objectives:
    Improve the bigeye tuna stock assessment
    01 Jan 2021 - 31 Dec 2024
    Funded
    Objectives:

    Objectives:
    Improve the yellowfin tuna stock assessment by exploring the use of an age-structured length-based catch-at-age statistical model with a monthly time step
    01 Jan 2021 - 31 Dec 2024
    Funded
    Objectives:
    Improve the yellowfin tuna stock assessment by exploring alternative hypotheses of stock structure and life-history
