Farmed Shrimp Welfare and Aquaculture Practices

Shrimp are farmed in enormous numbers globally with almost no welfare consideration. Growing evidence of their capacity for pain and stress argues for taking their welfare seriously in aquaculture systems.

Key Facts

Global shrimp aquaculture produces over 5 million tonnes annually — billions of individual animals
Shrimp have nociceptors and show avoidance learning after painful stimuli
Eyestalk ablation — removing one eye to induce spawning — is routine in shrimp hatcheries worldwide
Crowding in shrimp ponds leads to chronic stress, disease outbreaks, and high mortality rates
Ammonia and low oxygen levels in poorly managed ponds cause slow, distressing deaths
Shrimp Welfare Project estimates hundreds of billions of farmed shrimp suffer significantly each year

Welfare Considerations

The sheer number of farmed shrimp makes this one of the most numerically significant animal welfare issues in existence. Eyestalk ablation — performed without anesthesia — is a painful mutilation inflicted on broodstock females to induce reproduction. High-density farming causes chronic stress and predisposes shrimp to disease. Water quality failures cause mass deaths from oxygen deprivation. Given the scale and growing evidence of shrimp sentience, improving practices in shrimp aquaculture could reduce more individual animal suffering than almost any other single intervention.

What You Can Do

Support the Shrimp Welfare Project in their research and industry engagement work
Reduce consumption of farmed shrimp, particularly from countries with no welfare standards
Ask retailers and restaurants about sourcing and whether eyestalk ablation is prohibited
Advocate for including crustaceans in animal welfare legislation in your country
Support research into humane shrimp slaughter and welfare-positive aquaculture practices
