Farmed Salmon Hatchery Welfare Standards

Hatchery conditions during the first weeks of life establish the physiological and behavioral baseline for farmed salmon welfare throughout production.

Key Facts

Hatchery conditions including light, temperature, and density affect fry development
Deformities including skeletal malformations arise primarily from poor hatchery conditions
Early handling and stress sensitizes fish to subsequent stressors through epigenetic mechanisms
Optimal hatchery management reduces deformity rates from over 10 percent to under 2 percent
Vaccination at the smolt stage is essential but causes handling stress requiring mitigation

Welfare Considerations

Poor hatchery conditions establish lasting welfare deficits that persist through the entire production cycle. Investment in hatchery welfare standards produces lifelong benefits for every fish produced.

What You Can Do

Support certification schemes that include hatchery welfare in their standards
Advocate for mandatory deformity monitoring and reporting in salmon hatchery licensing
Choose salmon from farms with vertically integrated welfare standards from egg to harvest
