Lerøy Seafood Group has adopted poultry-based ingredients across its farms, while Grieg Seafood began using them in July. The processed chicken material includes bones and organs, offering a cheaper protein alternative. Poultry meal costs less than half the price of conventional fishmeal.

Norwegian research institute Nofima is investigating how poultry-based feed affects salmon health and quality, with research continuing until September 2027. A 2025 study involving 435,000 salmon found no significant differences in growth, mortality or fillet quality.

However, questions remain about antibiotic resistance and consumer transparency, as supermarkets are generally not required to disclose fish-feed ingredients on packaging.
