Farmed Salmon Acoustic Stress Management

Farmed salmon are sensitive to acoustic disturbance from boat engines, feeding systems, and environmental noise with welfare implications.

Key Facts

Salmon detect sound through their lateral line and inner ear systems
Repeated acoustic disturbance causes chronic stress and cortisol elevation
Noisy feeding systems and boat approaches can cause feeding disruption and injury
Acoustic deterrent devices used to repel seals cause significant disturbance to fish

Welfare Considerations

Acoustic environments in salmon aquaculture are rarely considered in welfare assessments. Fish welfare can be significantly affected by chronic noise exposure. Reducing unnecessary disturbance and designing quieter equipment improves welfare.

What You Can Do

Support aquaculture welfare research addressing acoustic environment
Advocate for fish welfare standards that include acoustic considerations
Choose salmon from certified operations with comprehensive welfare assessments
