Farmed Tilapia Harvesting Welfare

Tilapia harvest involves crowding, air exposure, and handling that cause acute welfare costs requiring best practice protocols.

Key Facts

Tilapia harvest from ponds involves seining or draining and manual sorting
Crowding causes hypoxia and physical injury from abrasion
Air exposure causes rapid respiratory distress in tilapia
Chilling in ice water reduces consciousness before killing in some premium operations
Electrical stunning before killing is used by some certified operations

Welfare Considerations

Harvest welfare for tilapia mirrors challenges across farmed fish species: crowding, handling, and slaughter all cause welfare costs that best practice can mitigate. Pre-slaughter chilling or stunning, rapid harvest, and reduced crowding duration are welfare improvements available to farms willing to invest in protocols.

What You Can Do

Choose tilapia from certified farms with harvest welfare protocols
Support organisations developing and promoting humane fish harvest standards
Advocate for welfare assessment during harvest as a mandatory certification requirement
