Peruse our original infographics, several of which are published in ISSF technical reports, on a variety of topics — from bycatch mitigationconservation measures, compliancefish aggregating devices (FADs), illegal fishing, and tuna stock status and harvest control rules to ISSF’s ProActive Vessel Register and Skippers Workshops.


ISSF’s mission is to undertake and facilitate science-based initiatives for the long-term conservation and sustainable use of global tuna stocks, reducing bycatch and promoting tuna ecosystem health.

Harvest Control Rules

Harvest control rules (HCRs), which are based on stock status, are agreed-upon guidelines for how much fishing of a particular species can take place.

MSC Certification

The Marine Stewardship Council (MSC) is a global certification program for fisheries. One of ISSF’s main objectives is supporting fisheries to become MSC certified without conditions. ISSF publishes reports that evaluate tuna stocks and RFMOs based on MSC criteria.

Skipper Workshops

More than 1,000 skippers from tuna vessels have attended ISSF educational workshops around the world, learning how to avoid bycatch when possible, safely handle bycatch species — such as sharks and turtles — to maximize their survival, and more.
