Non-Entangling & Biodegradable FADs Guide

ISSF’s Non-Entangling & Biodegradable FADs guide for tuna fishers, Regional Fisheries Management Organizations (RFMOs), governments, and vessel owners shows research-based best practices in Fish Aggregating Device (FAD) design — both to avoid bycatch and reduce marine pollution.

Four tuna RFMOs already require fleets in their regions that fish with FADs to use only non-entangling designs. Some RFMOs additionally encourage fleets to build those FADs with biodegradable materials. The guide, first published in 2012 and revised in 2019 to include the biodegradable recommendation, is available in several languages.

This report summarizes a workshop conducted by ISSF with the Ghanaian purse seine and pole and line tuna fleets to design biodegradable Fish Aggregating Devices (FADs).

This workshop is one of the first steps of a project funded by FAO-GEF Common Ocean Project that will test biodegradable FADs with one of the most important fleets in the Eastern Atlantic — the Ghanaian fleet, with 26 vessels fishing with FADs.

The aim of the workshop was to find an appropriate FAD structure to be tested with biodegradable materials available today, as well as to find the best strategy to test those FADs with the collaboration of the Ghanaian fleets.

Fishers worked separately in groups to design five biodegradable FADs. The number of experimental FADs to deploy, as well as the protocol to follow them at sea, was also determined during the workshop. This year the Ghanaian fleet will deploy 600 biodegradable FADs.
