Aquaculture Welfare

Farmed Tilapia Welfare Considerations

Tilapia is one of the world's most widely farmed fish, yet welfare standards in tilapia aquaculture remain poorly regulated globally.

Key Facts

Tilapia is the third most widely produced aquaculture species globally
High stocking densities in ponds and tanks cause chronic stress, fin damage and disease
Tilapia are often farmed in low-oxygen conditions that cause prolonged suffocation
Slaughter methods for tilapia frequently involve live chilling or asphyxiation in air
Evidence supports tilapia experiencing nociception and stress responses to harmful stimuli

Welfare Considerations

Tilapia welfare is often deprioritised due to assumptions about fish sentience and high commercial pressure to minimise costs. However, tilapia show clear behavioural and physiological responses to pain and stress. Crowding causes chronic cortisol elevation, immune suppression and increased aggression. Improving welfare requires reducing stocking densities, improving water quality, and adopting humane slaughter methods such as percussive stunning followed by bleeding.
