Billions of farmed shrimp are killed each year under conditions that may cause suffering, yet simple improvements to pre-slaughter handling can significantly reduce welfare impacts.
Shrimp welfare at slaughter is an area of genuine scientific uncertainty but growing concern. The precautionary principle - applied to sentience - suggests that where there is evidence of potential suffering, efforts to minimise it are warranted. The most practical immediate improvements are in pre-slaughter handling: reducing crowding stress, implementing rapid temperature reduction before killing, and developing electrical stunning systems for commercial adoption. Consumer pressure through certification schemes is the most accessible lever for change in a global industry that currently applies almost no welfare standards to this phase of production.
