Comprehensive salmon welfare in aquaculture addresses the full production cycle from egg to harvest, recognizing salmon as sentient fish with complex behavioral and physiological needs.
Comprehensive salmon welfare requires attention to welfare across the entire production cycle rather than focusing on single issues. Sea lice management involves difficult welfare trade-offs — infestations cause chronic suffering but some treatments also cause acute stress and mortality. Stocking density management balances economic efficiency against crowding-related welfare compromise. Genetic selection programs increasingly incorporate welfare traits alongside growth and disease resistance. Pre-slaughter welfare using validated humane stunning represents a significant opportunity to reduce suffering at the scale of billions of fish annually. Farm-level welfare assessment frameworks are maturing to enable systematic welfare monitoring and improvement.
