Shrimp Hatchery Welfare Challenges

Shrimp hatcheries are the starting point of farmed shrimp production, and welfare concerns at this stage include larval density, handling stress, and eyestalk ablation practices.

Key Facts

Global farmed shrimp production exceeds 5 million tonnes annually, mainly from Asia
Eyestalk ablation - removing the eyestalks of female shrimp to accelerate reproduction - is common practice
There is growing scientific evidence that shrimp can experience pain and stress
Larval shrimp in hatcheries are often reared at extremely high densities
Disease outbreaks such as Early Mortality Syndrome cause massive mortality in hatchery systems

Welfare Considerations

Shrimp hatchery welfare presents particular challenges because of the scale of production and the biological complexity of shrimp development. Eyestalk ablation is a painful mutilation that accelerates reproductive maturation but causes clear signs of distress and likely significant suffering. High larval densities and poor water quality in hatcheries can cause mass mortality. The emerging evidence for shrimp sentience means that welfare standards for hatchery operations need urgent development. Some progressive producers are beginning to explore ablation-free breeding programmes.

What You Can Do

Support certification schemes that prohibit eyestalk ablation in shrimp hatcheries
Choose shrimp from producers certified to welfare-aware standards such as BAP or ASC
Advocate for science-based shrimp welfare standards in aquaculture regulation
Learn about the scientific evidence for shrimp sentience and capacity for suffering
Support Shrimp Welfare Project and similar organisations working to improve farmed shrimp welfare
