Aquaculture Feed Sustainability - Welfare Connections

How aquaculture feed composition choices affect welfare of farmed fish and the wild fish populations used as feed.

Key Facts

Atlantic salmon require 1.1-1.2 kg of wild fish to produce 1 kg of farmed salmon in modern efficient systems
Reduction fisheries for fishmeal target small pelagic fish like anchovies and herring that are ecologically critical
Plant-based protein substitutes enable reduced reliance on fishmeal but may affect omega-3 content and fish health
Insect meal from BSFL represents a circular economy feed source reducing pressure on marine feed fish
Welfare impacts on billions of wild fish used for feed represent a significant but underacknowledged welfare concern
