Shrimp welfare science is advancing rapidly, with growing evidence supporting precautionary welfare measures in the world most farmed invertebrate group.
Shrimp welfare science has accelerated following legislative recognition of decapod crustacean sentience in the UK and growing scientific consensus supporting precautionary welfare measures. The scale of shrimp production means that modest welfare improvements per individual animal translate to enormous aggregate benefit if implemented globally. Shrimp in intensive aquaculture systems experience density stress, water quality fluctuation, disease pressure, and handling stress throughout their production cycle. Humane slaughter research is still developing, but the precautionary principle supports minimising potential suffering during killing. Consumer demand for welfare-certified shrimp is growing and provides market incentive for the producer-level changes that welfare science is beginning to support.
