Farmed Anchovy Alternatives and Feed Reform

Reducing dependence on wild-caught anchovies in aquaculture feed is a major animal welfare and sustainability goal, with several promising alternatives now in commercial use.

Key Facts

Aquaculture consumes approximately 20% of global wild fish harvest as fishmeal and fish oil
Insect meal (black soldier fly larvae) can replace 30-50% of fishmeal in many species diets
Single-cell protein from fermentation and algae-derived omega-3s are commercial alternatives
Norway has set targets to reduce fishmeal content in salmon feed by 50% by 2030
Plant proteins (soy, wheat gluten) already replace significant fishmeal volumes but have own environmental costs

Welfare Considerations

Every tonne of fishmeal replaced by alternative protein sources reduces the welfare burden on billions of wild fish. The feed transition in aquaculture is therefore one of the highest-leverage interventions available in food system animal welfare. Black soldier fly larvae are nutritionally excellent fishmeal substitutes and their own welfare needs are uncertain but likely minimal. Algae-derived DHA and EPA omega-3 oils eliminate the need for fish oil entirely. Regulatory and consumer pressure is driving rapid innovation: several major salmon producers now produce low-fishmeal feeds commercially. The welfare math strongly favors accelerating this transition.

What You Can Do

Support aquaculture certification schemes that set and verify fishmeal reduction targets
Choose omega-3 supplements from algae rather than fish oil sources
Encourage your supermarket to ask farmed fish suppliers about their feed sourcing
Donate to organizations researching scalable fishmeal alternatives
Support policy requiring fishmeal reduction targets in aquaculture licensing
