Illegal incidents and violations related to Atlantic salmon fishing in Newfoundland and Labrador, Canada, during 2001–2020
Resource user compliance is a key element in effective fisheries management. Herein, we examine two decades of enforcement records pertaining to Atlantic salmon from Newfoundland and Labrador, Canada. Illegal incidents were negatively correlated with the number of licensed anglers but not salmon abundance. Over two decades, illegal incidents declined by 66%, even after correcting for the positive relationship between enforcement effort and illegal incidents. This decline was primarily driven by a 67% reduction in netting and jigging-related violations, which were likely to impose the highest levels of mortality on adult salmon among violations examined. Additionally, illegal incidents and violation types did not increase as a result of management changes. While Newfoundland and Labrador remains one of the last strongholds for Atlantic salmon, we encourage other jurisdictions to monitor fisheries compliance to better understand the social-ecological landscape that is crucial to supporting healthy fisheries.
期刊介绍:
Fisheries Management and Ecology is a journal with an international perspective. It presents papers that cover all aspects of the management, ecology and conservation of inland, estuarine and coastal fisheries.
The Journal aims to:
foster an understanding of the maintenance, development and management of the conditions under which fish populations and communities thrive, and how they and their habitat can be conserved and enhanced;
promote a thorough understanding of the dual nature of fisheries as valuable resources exploited for food, recreational and commercial purposes and as pivotal indicators of aquatic habitat quality and conservation status;
help fisheries managers focus upon policy, management, operational, conservation and ecological issues;
assist fisheries ecologists become more aware of the needs of managers for information, techniques, tools and concepts;
integrate ecological studies with all aspects of management;
ensure that the conservation of fisheries and their environments is a recurring theme in fisheries and aquatic management.
