Shrimp farming is one of the most intensive forms of aquaculture, involving hundreds of billions of animals with essentially no welfare regulations. Reform is in its earliest stages.
Shrimp welfare represents perhaps the largest numerically significant unaddressed welfare issue in animal agriculture. If shrimp have any capacity for suffering — a question that remains scientifically uncertain but increasingly plausible — the hundreds of billions farmed annually represent an enormous potential welfare burden. Eyestalk ablation is the most clearly identified welfare concern: removing the eyestalk to induce spawning causes physical injury and likely pain. Crowding stress, disease exposure, and slaughter practices without stunning are additional concerns. The welfare movement is only beginning to engage seriously with shrimp welfare; the scientific foundation and the regulatory and market levers needed for reform are in very early stages. Consumer awareness and demand for welfare consideration in shrimp products is minimal.
