Marine fisheries are a globally significant source of economic and food security, however high bycatch rates can threaten marine biodiversity putting both ecosystems and fisheries at risk for degradation. Although bycatch reduction technologies exist that can reduce the uptake of bycatch without significantly impacting target catch, bycatch rates remain high. To understand the factors that affect fishers’ change readiness we reviewed 15 interview-based studies assessing fishers perspectives on bycatch and bycatch reduction strategies. In sum, the perspectives of 1,991 fishers were assessed in these studies across 10 different countries from 2006-2023. One key finding that arose was the potential importance of agency. This factor closely relates to change readiness and was identified as an essential component for effective bycatch reduction. Additionally, it was discovered that the kind of proposed strategy is important. Bycatch reduction methods that are equally effective in capturing target catch while reducing non-target catch and are accessible are more likely to have favorable responses from fishers. Agency and change readiness are interconnected and may be influenced by a variety of factors such as income, education, experience, and beliefs/values. Incentives and education/engagement programs may be useful in fostering fishers’ willingness for change and improving the efficacy of bycatch reduction strategies.
