Milkfish: Welfare in Philippine and Asian Aquaculture

Key Welfare Facts

Milkfish is the most important cultured marine fish in the Philippines, with a history dating back centuries.
Traditional extensive pond culture in mangrove areas maintained relatively naturalistic low-density conditions.
Intensification toward cage culture and semi-intensive pond systems raises stocking density and welfare challenges.
Mangrove loss for milkfish pond development has significant ecological impacts linked to long-term welfare concerns.
Milkfish tolerate wide salinity ranges but require careful acclimation to prevent osmotic stress and mortality.
Slaughter practices in wet markets including live sale and inadequate killing methods represent significant welfare concerns.

Welfare Assessment

Milkfish welfare spans ecological and individual animal concerns connected to aquaculture intensification and mangrove conservation. Supporting sustainable milkfish production that protects mangrove habitats addresses both ecological and individual welfare.

What You Can Do

Choose milkfish products from operations that have ceased mangrove conversion and use low-density systems
Support restoration of mangrove habitats converted for aquaculture in Philippine and Indonesian coasts
Advocate for humane slaughter standards in wet market milkfish sales
Engage with certification bodies to incorporate milkfish welfare standards in sustainable seafood schemes
