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. -

7 Project(s)01 Jan 2018 - 31 Dec 2018FundedObjectives:
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 2021FundedObjectives:
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 EPO01 Mar 2021 - 31 Aug 2022FundedObjectives:
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.Objectives:
Evaluate whether changes in the environment may have contributed to the increases in YFT catches by the purse seine fleet. Specifically, investigate the occurrence of trends/shifts in YFT suitable habitat and corresponding effects in catch rates and length composition, that may explain recent increases in catch.01 Jul 2021 - 01 Jul 2023FundedObjectives:
- Produce forecasted dynamic species and vessel distributions under different anomaly and climate change scenarios in the near, mid and long-term based on changing environmental drivers.
- Quantify shifts in overlap among species and vessels given shifting habitat for both.
- Understand the impact of climate anomalies, changing oceanographic conditions and future scenarios on forecasted dynamic species and vessel distributions with a specific focus on forecast skill and accounting for uncertainty.
Objectives:
To use ongoing work by tuna-Regional Fisheries Management Organizations (t-RFMO’s) to inform a workplan to restructure the Ecosystem Considerations document into two ecosystem-advice products for management consideration (1) an Ecosystem Report Card (“EcoCard”) consisting of indicators considered to best represent ecosystem status on an ecoregion level and (2) a corresponding Ecosystem Status Assessment detailing ecosystem status. Together, these products aim to support possible operationalization of the Ecosystem Approaches to Fisheries Management (EAFM) in the EPO. To improve communication of ecosystem status and harmonize with t-RFMOs.Objectives:
To discuss the current work that IATTC is doing to understand and prepare for the effects of climate change, highlight various tools and frameworks that other countries and international organizations have developed to promote climate-resilient fisheries, and propose a climate change workplan for IATTC that will allow us to better understand, account for, and prepare for the impacts climate change may have on fisheries, its target species, non-target species, and the EPO
