This document summarizes recommended best practices for tropical tuna FAD fisheries, linked to MSC Performance Indicators.

This paper describes best-practice monitoring activities for each MSC PI based on data needs, as well as to identify data monitoring systems, sources, and technology that can be used to collect this information.

Key recommendations and best practices, useful for improving scores against the MSC standard or to address common weaknesses in FIP Action Plans

This report provides practical examples that fleets could adopt as their FAD management policies. It is an update of ISSF Technical Report 2019-11.
