Tilapia welfare in aquaculture requires attention to the specific needs of these widely farmed tropical fish, including water quality, social behavior and humane production practices.
Tilapia welfare has received less research attention than salmon and trout despite vastly greater production volumes. Existing evidence shows tilapia have pain nociceptors, stress hormone responses and behavioral indicators of poor welfare comparable to other teleost fish. Welfare issues in tilapia aquaculture include high stocking densities creating chronic stress, aggressive dominance hierarchies in group housing, cold stress during transport in cooler climates, and variable pre-slaughter welfare practices. The scale of tilapia production means that even modest welfare improvements applied across the industry would benefit enormous numbers of fish. Developing tilapia-specific welfare standards represents a significant and underaddressed welfare opportunity.
