Salmon Hatchery Welfare Practices

Salmon hatchery management during the early life stages sets the foundation for fish welfare throughout the production cycle. Key welfare interventions at this stage have lasting effects.

Key Facts

Salmon begin their farmed life in freshwater hatcheries as eggs and alevins
Handling during egg sorting, grading, and vaccination causes acute stress responses
Crowding during grading and transport is a significant early welfare challenge
Vaccination programmes protect against disease but involve handling and injection stress
Feed management during first feeding is critical for survival and subsequent welfare

Welfare Considerations

Early welfare experiences in the hatchery may have lasting effects on salmon behaviour and stress reactivity throughout their lives. Gentle handling protocols, minimised crowding during grading, and appropriate anaesthesia for vaccination procedures reduce acute stress at this stage. Smoltification — the transition from freshwater to saltwater life — is a physiologically demanding period requiring careful management of water quality, temperature, and social density. Investment in hatchery welfare has both direct welfare and downstream production benefits.

What You Can Do

Choose certified salmon from hatchery-to-harvest welfare-assessed supply chains
Support research into hatchery welfare practices and their long-term effects on fish wellbeing
Advocate for welfare standards that extend throughout the salmon production cycle
Ask retailers about hatchery welfare standards in their salmon supply chains
Support development of hatchery welfare certification standards
