Norwegian salmon farms are taking huge amounts of wild fish from West Africa, mining the food security of the region, according to a report from the U.K.-based NGO Feedback. The analysis comes as the industry faces a wave of public opposition after revelations of high mortality rates and the sale of fish deemed unfit for human consumption, along with accusations of antitrust violations by the European Commission.

The report, titled “Blue Empire,” was produced with other organizations including Greenpeace Africa and The West African Association for the Development of Artisanal Fishing and published in January. It quantifies the use of fishmeal and fish oil imported from Mauritania, Senegal and the Gambia in the production of feed for salmon farms in Norway, the world’s main producer of Atlantic salmon (Salmo salar).

According to the report, in 2020, Norwegian salmon farms required almost 2 million metric tons of edible wild fish to produce fish oil intended for feeds that produced nearly 1.5 million metric tons of farmed salmon.

Up to 7% of these wild fish (123,000-144,000 metric tons) were small pelagic species caught along the coasts of West Africa, where they could have fed between 2.5 million and 4 million people, according to the report.
