In Canadian Pacific salmon Oncorhynchus spp. commercial fisheries, a policy of selective fishing includes a mandatory release program intended to reduce impacts on vulnerable populations. However, there remain concerns of noncompliance with these regulations, potentially resulting in higher mortality of released fish than is accounted for. Though estimations of postrelease mortality have improved the management of commercial fisheries, the influence of fishers’ behavior is not directly considered by the regulatory framework. Additionally, perceptions of the selective fishing strategy have not been evaluated among fishers, despite knowledge that their acceptance of regulations is critical to successful management outcomes. We conducted 21 semistructured interviews with fishers from the commercial purse seine fleet for Pacific salmon about their perceptions of selective fishing, and found that attitudes towards regulations and managers are a primary determinant of compliance. We also found that greater incentives for selective fishing practices and improved communication among the fishing, management, and scientific communities would likely enhance support for management systems among members of the purse seine fleet.
