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 infographic shows four steps that purse seine fishers can take to decrease the bycatch of silky sharks (Carcharhinus falciformis) and improve their survival rate.

Steps 1-2 focus on fishing practices, and steps 3-4 focus on silky shark release techniques.

The infographic is based on an ISSF research report: ISSF 2016-17: Mitigation of Silky Shark Bycatch in Tropical Tuna Purse Seine Fisheries.
