Non-Entangling & Biodegradable FADs Guide - International Seafood Sustainability Foundation

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

Created in November 2020, this infographic explains our research on how acoustic technology like echosounders could be used by purse-seine vessels to fish more selectively at fish aggregating devices (FADs).

Echosounders can be used to identify the acoustic signatures of different tuna species, allowing FAD fishers before they make a set to better target the tuna species whose stocks are at healthy levels — reducing overfishing and bycatch of non-target tuna and other marine species.
