Practical welfare indicators for tilapia farms enable routine assessment of fish welfare across the production cycle.
Tilapia welfare monitoring in commercial systems requires practical tools that farm staff can apply routinely without specialist expertise. Behavioural indicators including schooling coherence, surface activity, and feeding response provide early warning of welfare problems. Body condition assessment identifies nutritional welfare problems. Fin erosion rates indicate crowding or tank design issues. Mortality trends provide welfare outcome data at the population level. A comprehensive welfare monitoring programme for tilapia integrates all these indicators into a routine assessment protocol that enables early intervention before welfare problems escalate to clinical disease.
