Wild Caught vs. Farmed Shrimp Welfare

Shrimp are among the most consumed seafood globally, raising complex welfare questions about both wild capture methods and intensive aquaculture practices.

Key Facts

Over 5 million tonnes of shrimp are produced globally each year
Wild shrimp are often caught with trawls that also capture large bycatch
Shrimp have nociceptors and show avoidance learning after painful stimuli
Farmed shrimp are often raised at extreme densities in effluent-rich ponds
Eyestalk ablation — removal of eyes to induce breeding — is standard in many hatcheries

Welfare Considerations

Evidence from neuroscience suggests shrimp likely experience nociception, meaning harmful procedures cause something analogous to pain. Eyestalk ablation without anesthesia is particularly concerning. Wild-caught shrimp face prolonged suffocation during haul-out. Welfare improvements are possible — some producers now use electrical stunning before processing.

What You Can Do

Support Shrimp Welfare Project efforts to improve hatchery practices
Choose shrimp certified under higher-welfare standards where available
Reduce shrimp consumption or choose alternatives with lower welfare impact
Advocate for anesthetic use during eyestalk ablation in shrimp hatcheries
