Stocks of cod in the North Atlantic are being increasingly depleted by the effects of climate change. Because the water is getting warmer, the fish are growing more slowly, and their stocks are already weakened by overfishing.In the Barents Sea, the remaining cod are finding their way into Russian waters. Problems for the Norwegian fishermen are an obvious consequence. In Norway, cod is one of the basic foodstuffs, and the fish are an important export item. They’re used for making fish sticks and are eaten dried in Spain and Portugal.
