Penaeid Shrimp Welfare in Global Aquaculture

Penaeid shrimp species dominate global aquaculture, with welfare considerations spanning crowding, disease management and slaughter practices across major producing nations.

Key Facts

Penaeid shrimp include whiteleg, tiger and giant tiger prawn — billions farmed annually
Produced in tropical regions including Asia, Latin America and West Africa
Eyestalk ablation is used in broodstock to induce spawning — a painful procedure
Post-larvae are often transported live over long distances — significant welfare stress
Slaughter by live boiling or freezing without stunning is standard in most facilities

Welfare Considerations

Penaeid shrimp welfare is compromised across multiple life stages — eyestalk ablation in broodstock females causes pain and impairs normal physiology; intensive larval rearing creates disease pressure and crowding stress; long-distance live transport causes mortality and suffering; and slaughter without stunning exposes billions of animals to potential pain. As evidence for crustacean sentience grows, the welfare gap in penaeid shrimp production becomes increasingly ethically significant.

What You Can Do

Advocate for elimination of eyestalk ablation in shrimp broodstock management
Support mandatory pre-slaughter stunning requirements for commercially farmed shrimp
Choose shrimp certified under schemes that address welfare across the production cycle
Reduce consumption of uncertified tropical shrimp from intensive sources
Support research into humane broodstock management without eyestalk ablation
