Marine Shrimp Larval Welfare in Hatchery Systems

Welfare considerations for shrimp larvae during the hatchery phase of production.

Key Facts

Shrimp larvae pass through multiple developmental stages before reaching juvenile size
Larval density, water quality, and feed quality directly affect survival and welfare
Antibiotic overuse in shrimp hatcheries creates resistance and welfare concerns
Probiotics and biosecure hatchery design are improving larval welfare outcomes

Welfare Considerations

Shrimp larval welfare is affected by extreme crowding in hatchery tanks, water quality management, and disease treatment practices. Antibiotic overuse, while targeting disease, creates resistance and may affect larval microbiomes. Welfare-informed hatchery management maintains optimal water quality, uses probiotics to support larval health, and reserves antibiotics for genuine disease emergencies. Larval welfare quality affects the entire downstream production cycle.

What You Can Do

Support certified shrimp hatcheries with documented reduced antibiotic use
Advocate for probiotic-based larval management as the welfare-improving industry standard
Choose certified shrimp products that include hatchery welfare standards in their certification scope
