Vannamei Shrimp: Welfare in Global Aquaculture

Key Welfare Facts

Vannamei is the world's most farmed crustacean with global production exceeding 4 million tonnes annually.
Intensive pond culture at extreme densities creates severe water quality challenges affecting welfare at scale.
Eyestalk ablation of broodstock females to induce spawning is routine, representing a significant welfare concern.
Early mortality syndrome causes catastrophic losses through bacterial toxins affecting young shrimp hepatopancreas.
Ammonia and hydrogen sulphide accumulation in intensive ponds causes gill damage and mass mortality events.
Welfare regulatory frameworks for shrimp are essentially absent despite the vast scale of global production.

Welfare Assessment

Vannamei shrimp welfare affects billions of individual animals annually in an almost entirely unregulated industry. Supporting certification schemes that begin to address stocking density and disease management provides the most accessible market-based welfare improvement.
