Aquaculture

Farmed Grouper Asian Mariculture Welfare

Grouper aquaculture is expanding rapidly in Southeast Asia, with welfare challenges from capture of wild juveniles for grow-out, high stocking densities, and disease management.

Key Facts

Many grouper species are not yet closed-cycle in aquaculture, relying on wild-caught juveniles
Wild juvenile capture stresses animals through netting, handling, and transport
Viral nervous necrosis (VNN) is a major disease causing high mortality in grouper farms
High densities cause aggression and fin damage in territorial grouper species
Market demand drives live grouper trade with high transport mortality

Welfare Considerations

Grouper aquaculture welfare is compromised at multiple points from wild capture through grow-out and live transport. Species-specific welfare standards are urgently needed.

What You Can Do

Avoid purchasing live grouper given transport mortality concerns
Support research into closed-cycle grouper breeding to eliminate wild capture
Advocate for disease management standards in grouper certification schemes
Raise awareness of grouper welfare in seafood sustainability discussions
