The European Commission is investigating top Norwegian salmon-farming companies, including Mowi, Cermaq, Grieg, Bremnes, Lerøy, and SalMar, for alleged price fixing in the salmon spot market. The companies are suspected of colluding to influence prices, in violation of European Union antitrust rules. The news led to a sharp drop in the share prices of the publicly traded companies. If found guilty, each company could be fined up to 10% of their annual worldwide turnover.
