Farmed Salmon Net Pen Integrity Welfare

Net pen integrity failures cause catastrophic escapes and expose remaining fish to predators, with significant welfare consequences.

Key Facts

Net pen failures cause salmon escapes - a problem for both wild and farmed fish welfare
Remaining fish after partial net failure may be exposed to predators entering the pen
Predator exclusion nets above pens prevent sea lion and bird attacks
Regular net inspection and replacement reduces integrity failure risk
Escape events trigger immediate welfare and biosecurity response protocols

Welfare Considerations

Net pen failures expose confined, domesticated salmon to predator access - a severe welfare event. Remaining fish experience acute fear and injury from predator attacks. Regular inspection, maintenance, and appropriate predator exclusion technology are welfare imperatives in sea cage salmon farming.

What You Can Do

Support aquaculture certifications requiring net integrity monitoring standards
Advocate for escape prevention as a welfare as well as environmental standard
Choose certified salmon from farms with transparent escape event reporting
