Milkfish (Chanos chanos) Welfare in Philippine Aquaculture 2026

Milkfish is the national fish of the Philippines and a cultural staple, farmed in extensive and semi-intensive systems across Southeast Asia.

Key Facts

Milkfish is farmed in brackish water ponds (bangus ponds) across the Philippines, Indonesia, and Taiwan
Philippine production exceeds 300,000 tonnes annually, making it the country's most important farmed fish
Traditional extensive culture relies on natural productivity of algal mats (lab-lab) with minimal feed inputs
Semi-intensive production uses supplemental feeds and achieves higher densities and growth rates
Harvest is often by traditional net methods followed by live sale or ice storage without stunning

Welfare Considerations

Milkfish welfare within traditional Philippine bangus culture is shaped by low stocking densities and natural feeding in extensive systems, which provide relatively good welfare conditions. The transition to semi-intensive production increases stocking density and reduces available space per fish. Harvest and post-harvest handling are the primary welfare concerns - live fish are often transported long distances to markets, experiencing chronic stress, crowding, and oxygen depletion. Cultural norms around live fish preference at market create structural barriers to pre-slaughter stunning adoption. Developing welfare guidance appropriate to the cultural and economic context of Philippine bangus farming is an important step for improving milkfish welfare at scale.

What You Can Do

Support development of culturally appropriate welfare guidelines for Philippine milkfish aquaculture
Advocate for humane slaughter methods in export-oriented milkfish production
Encourage research into stress-reduction during transport and holding of live milkfish
Choose milkfish products from producers demonstrating welfare-conscious management practices
