Method. 73 companies registered on industry code 03.211 (Operation of marine fish farms) with filed accounts and at least one million kroner in revenue. The figures come from the Norwegian Register of Business Enterprises and are public. Operating margin is operating profit divided by operating revenue.

Each company appears with the most recent accounts we hold for it. For the great majority that is the 2024 filing. Around eight per cent had already filed for 2025 when we collected, and for those the 2025 figures apply. We therefore write "latest accounts" rather than naming a single year.

We show one cross-section and no trend line. Our database has broad coverage for the most recent accounting year, but only a small and non-random sample for earlier years. A curve over time would therefore measure who we happened to collect, not what happened in the industry.

Companies with under one million in revenue are excluded, because dormant limited companies would otherwise pull the median down. We do not publish an industry page until we hold at least 30 companies.

This is a description of an industry, not a ranking of companies. We name no individual company here.
