ISSF investigates and promotes science-based approaches for ensuring the long-term sustainability of global tuna stocks and the marine ecosystem.

The ISSF team works collaboratively with peer scientists, academics, environmental experts, governing bodies, and other stakeholders on issues where we can advance our understanding about sustainable fishing — and make a positive impact.

We publish reports, develop resources, and host events that support fishery health in key areas: tuna conservation, fish aggregating device (FAD) management, marine ecosystem health, bycatch reduction, capacity management, and illegal fishing prevention.

More than 70% of ISSF’s resources support original, collaborative research — including on the water and onboard tuna vessels, alongside fishers — conducted by fisheries and marine scientists.


Scientific Reports

Our scientists document activities and insights from ISSF at-sea research projects, international workshops and meetings, and fisheries data analysis.

Best Practices Reports

In our best practices reports, we share ISSF science and policy recommendations for sustainable fisheries management, including to earn Marine Stewardship Council (MSC) certification.

Best-Practices Resources for Fishers

In addition to advocating best practices in fisheries management to RFMOs — through reports, snapshots, and other materials — ISSF develops best-practices resources for fishers, including skippers workshops and guidebooks and an illustrated guide for building jelly-FADs, which are both non-entangling and biodegradable.


At-Sea Research Projects

Our science team researches a variety of sustainable fishing approaches — such as biodegradable FADs like jelly-FADs and the acoustic discrimination of species at FADs — including in partnership with commercial fleets and research associations. We publish our findings in ISSF scientific reports and leading journals.

Data Collection & Analysis

We compile, evaluate, and publish data and findings that are useful to fisheries managers and other stakeholders, covering tuna stock status, FAD management, bycatch rates and mitigation efforts, electronic monitoring, purse-seine fleet capacity, and other topics. ISSF scientists also contribute to RFMO working groups and meetings.

MSC Fishery-Certification Support

ISSF best-practices research insights and reports can help fishers and other stakeholders — including participants in fishery improvement project (FIPs) — to better understand and follow practices to meet MSC fishery-certification criteria.

Skipper & Observer Resources

We lead workshops with tuna vessel skippers on bycatch mitigation techniques and offer sustainable-fishing guidebooks for observers and purse-seine, longline, and pole-and-line fishers.


ISSF RFMO Priorities

We’ve prioritized the issues RFMOs must make progress on this year.

Scientific Advisory Committee

The fisheries and marine scientists on ISSF’s Scientific Advisory Committee (SAC) help to guide our research activities and publications.

SAC members offer objective information and input to ISSF’s scientists, leadership, and Board of Directors on a volunteer basis.
