Rainbow trout farming is the UK's most significant aquaculture sector, with welfare standards improving through industry-led and legislative initiatives.
Rainbow trout welfare in UK aquaculture is increasingly supported by research-informed standards. Key welfare events include crowding during grading and harvesting, and pre-slaughter handling. Research shows that broodstock management, vaccination protocols, and lice treatment all cause welfare-relevant stress responses. RSPCA Assured certification requires specific welfare management including minimum space requirements, water quality monitoring, and humane slaughter. Electrical stunning before percussive slaughter provides a welfare-friendly processing method.
