Norwegian fish farming results in the export of 'production' grade salmon, which is cheaper due to defects or scars. This has created a market distortion in the EU, where these fish are competing directly with 'premium' or 'normal' salmon, leading to a price gap of around €4.30 to €4.50 per kilogram. The price difference is hindering the competitiveness of the EU industry, resulting in reduced production and layoffs. The European Commission's trade department is investigating Norway's ban as a potential conflict with international trade law.
