Farmed Shrimp Welfare: Density, Disease, and Slaughter

Farmed shrimp production has grown dramatically over recent decades, raising profound welfare questions about the billions of animals subjected to intensive aquaculture conditions.

Key Facts

Global farmed shrimp production exceeds 5 million tonnes annually — mostly Whiteleg shrimp
Stocking densities in intensive ponds can exceed 300 shrimp per square metre
Disease — particularly White Spot Syndrome Virus — causes catastrophic mortality events affecting billions of animals
Most shrimp are slaughtered by chilling on ice or direct immersion in iced water without prior stunning
The Shrimp Welfare Project estimates over 400 billion farmed shrimp experience potentially painful deaths annually

Welfare Considerations

Farmed shrimp face welfare challenges at every stage: overcrowded ponds, disease-driven mass mortality, transport stress, and slaughter without stunning. The scale is staggering — shrimp may represent the largest aggregate animal welfare challenge in agriculture by individual count. Electrical stunning methods for shrimp have been developed and are being piloted. Even modest improvements adopted across the industry would benefit vast numbers of animals. Consumer and retailer pressure is beginning to shift procurement standards.
