Shrimp is one of the most consumed seafood products globally, and the welfare implications of intensive shrimp farming are substantial and largely invisible to consumers.
Commercial shrimp farming raises welfare concerns at multiple points. Eyestalk ablation, which triggers molting and spawning, is painful based on behavioral and neurological evidence. Pond densities create competition, disease pressure, and chronic stress. Harvest typically involves pumping, crowding, chilling, and processing without consideration of humane killing. The welfare science of shrimp is advancing rapidly, with studies documenting avoidance learning and responses consistent with pain. As with insects, the scale of shrimp farming — involving trillions of individual animals — means that even a small probability of sentience represents enormous moral stakes.
