Farmed Salmon Broodstock Welfare

Broodstock salmon are held for extended periods as the genetic source for farmed populations, with welfare challenges from sustained captivity, reproductive manipulation, and stripping procedures.

Key Facts

Broodstock salmon are held in freshwater tanks for 2-4 years before reproductive use
Stripping of eggs and milt involves capture, air exposure, and physical manipulation
Anaesthesia during stripping reduces acute stress and is increasingly standard
Hormonal manipulation to advance spawning timing alters natural physiology
Genetic selection pressure on broodstock raises welfare questions about trait extremes

Welfare Considerations

Broodstock welfare receives less attention than grow-out salmon welfare despite sustained captive stress. Improved handling protocols and anaesthesia use reduce preventable suffering.

What You Can Do

Support certification schemes including broodstock welfare standards
Advocate for mandatory anaesthesia during broodstock stripping procedures
Raise awareness of broodstock as an overlooked welfare category in salmon farming
Support research into broodstock welfare indicators and management improvements
