Marine Harvest, the world’s largest producer of farmed salmon, has put a bounty on the heads of salmon that escaped from one of its cages in Norway. The company believes thousands of salmon could have escaped. Fearing damage the farmed fish may do to wild stocks, Marine Harvest will pay local fishermen 60 Euros ($90) per fish returned.

From this Al Jazeera story, the salmon escaped from a hole in a huge underwater cage that held 127,000 fish. Marine Harvest has repaired the hole, put nets around it, and offered the bounty. The hole was likely caused by stormy weather, although seals have also been known to make holes in salmon cages. Escaped farm salmon can often outcompete wild fish and interbreed with them, producing genetically inferior offspring.
