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.

Description

This report summarizes the results of a project in the Maldivian waters to test the lifetime and robustness of biodegradable ropes for use in Fish Aggregating Devices (FADs). Three types of biodegradable ropes were evaluated for robustness and other characteristics over one year at sea: (i) twisted 100 % cotton rope; (ii) twisted 50% cotton and 50% sisal rope; and (iii) cotton, sisal and linen rope with loops. The authors discuss those results as well as recommendations for the successful use of biodegradable materials in FADs.
