ISSF sponsors at-sea research to find the best non-entangling designs and natural materials for fish aggregating devices (FADs) that can biodegrade.
This map — updated in September 2025 — shows where new trials and deployments of biodegradable FADs are taking place around the world. It also indicates the tuna fishing gear types, fleets, and dates for each project, corresponding to an ISSF research compendium report.
