  • 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 Jan 2016 - 31 Dec 2018
    Funded
    Objectives:
    Estimate the post-release survival of silky sharks captured by longline vessels in the equatorial EPO, using archival tags
    01 Jan 2018 - 31 Dec 2020
    Funded
    Objectives:
    Estimate post-release survival of silky sharks captured by Mexican longline vessels in the eastern tropical Pacific, utilizing a best handling practice, and define boundaries encompassing the probable distribution silky shark pupping areas in the EPO
    01 Jun 2021 - 01 Jun 2023
    Funded
    Objectives:
    • Quantify baseline capture and survival probabilities of mobulid species and identify best practices for handling and release
    • Identify vertical and horizontal habitat use of the species to improve selectivity
    • Quantify the accuracy of onboard observer species identification
    • Characterize population genetic structure and effective population size across the Eastern Pacific for four mobulid species.
    01 Jan 2020 - 31 Dec 2021
    Funded
    Objectives:
    Explore the effectiveness of different types of spatial and temporal closures in reducing bycatch with the lowest losses in target catch
    01 Aug 2015 - 01 Feb 2022
    Funded
    Objectives:
    Construction of non-entangling FADs from biodegradable materials, not only to decrease mortality of non-target species by net-webbing entanglement, but also minimize contributions to ocean debris and pollution by commercial tuna fishing.
    01 May 2021 - 31 May 2023
    Funded
    Objectives:
    • Evaluate the extent of stranded, abandoned or lost FADs (SAL-FADs) in the EPO.
    • Evaluate the impact of SAL-FADs on coastal areas and islands of the EPO, with special emphasis on identification of deploying locations.
    • Identify or develop oceanographic models to forecast strandings of FADs.
    • Based on findings, develop mitigation and management measures and strategies to minimize SAL-FADs. Promote recovery of SAL-FADs and evaluate its effectiveness.
    01 Dec 2020 - 31 Dec 2022
    Funded
    Objectives:
    Minimize the impacts caused by lost and abandoned FADs on sea turtles, while also defining future guidelines to reduce the impact of FAD structures on sea turtles´ habitats
    01 Jan 2018 - 31 Dec 2018
    Funded
    Objectives:
    To better understand environmental drivers that might be responsible for increasing the vulnerability of non-target species to being caught in EPO fisheries, and devise management measures that may reduce their vulnerability to capture (e.g. space-time closures).
    01 Jun 2018 - 31 Dec 2021
    Funded
    Objectives:
    Estimate the optimal microturbulence and wind speed for the survival of yellowfin larvae and examine any association between yellowfin recruitment and historical wind speeds in the EPO
    01 Mar 2021 - 31 Aug 2022
    Funded
    Objectives:
    Contribute to the development of high-resolution dynamic habitat models for key non-target species and ecological functional groups impacted by tuna fisheries to better understand the dynamics of target-bycatch-environment co-occurrence and assess the vulnerability of the species under existing and projected effort and environmental regimes using EASI-Fish.
