Aquaculture Welfare

Farmed Fish Feed Welfare Implications

The composition and delivery of feed affects farmed fish welfare through nutritional adequacy, feeding competition, and the welfare of the fish and marine animals used as feed ingredients.

Key Facts

Marine fishmeal derived from wild-caught small pelagic fish is a major aquaculture feed ingredient
Feed formulation affects gut health, immunity, and behaviour in farmed fish
Competitive feeding at overstocked densities causes injury and chronic stress
Automatic feeding systems can deliver feed on demand, reducing competition
Plant protein sources and insect meal are increasingly replacing fishmeal in feeds

Welfare Considerations

Feed represents a critical welfare interface: inadequate nutrition causes disease and suffering while competitive feeding at high densities causes chronic stress and injury. Additionally, the welfare of billions of small fish caught to produce fishmeal raises broader ethical questions about aquaculture's overall welfare footprint.

What You Can Do

Support aquaculture standards that include nutritional welfare requirements
Advocate for research into plant and insect-based feed replacements for fishmeal
Choose certified aquaculture products from operations with responsible feed sourcing
