What happens when one of the world’s largest fish stocks is driven beyond its limits?
By the late 1960s, the Norwegian spring-spawning herring was in clear decline. Catches that had once reached millions of tonnes collapsed to almost zero. Spawning grounds fell silent. By 1970, the fishery had effectively ended.

This was not a natural accident. It was the result of human decisions. Warnings were known. Scientific advice existed. Yet fishing pressure continued to rise, while management failed to keep pace.
Herring was not just a commercial species. It was a central part of the marine ecosystem. When it disappeared, the balance of the sea shifted. The effects spread through food chains and into coastal societies.
Across Norway, Iceland, the Faroe Islands, and north-west Russia, the impact was immediate and severe. Fleets were laid up. Processing plants closed. Jobs were lost. Entire communities faced long-term damage.
Action finally followed. Fishing was stopped. Science was given authority. For many years, recovery did not come, and uncertainty remained high.
Then, in the early 1980s, a strong year-class appeared. It confirmed that recovery was possible — but only under strict control. The stock slowly rebuilt, guided by science and shared responsibility among nations.
