How disease prevention in shrimp farming intersects with welfare concerns and the development of more humane production practices.
Farmed shrimp welfare occupies a scientifically uncertain but ethically serious space. While the question of shrimp sentience and pain experience remains debated, the precautionary principle suggests that operations involving billions of individuals warrant welfare consideration. Disease prevention is a convergence point where production interests and animal welfare align: operations that maintain water quality, avoid extreme stocking densities, use biosecurity to prevent disease introduction, and employ alternative treatments rather than antibiotics provide environments where shrimp can complete their biological needs with less physiological stress and lower mortality. The mass die-offs that characterize poorly managed disease outbreaks, regardless of the welfare significance to individual shrimp, represent production failures that incentivize welfare-improving practices.
