Atlantic salmon is the most studied farmed fish species for welfare; this comprehensive overview covers the key welfare issues and evidence-based improvements at each production stage.
Atlantic salmon welfare represents the most advanced welfare science and policy development for any aquaculture species. From hatchery conditions through sea pen density management to slaughter method requirements, welfare frameworks for salmon are developing rapidly in producer countries. The improvements achieved demonstrate that significant welfare gains are possible in commercial aquaculture when scientific evidence, certification standards, and market demand align. The salmon welfare model provides lessons applicable to the development of welfare standards for other aquaculture species.
