Currents Influence Fish Stocks: More Cod in the Barents Sea

The entire North Atlantic warmed up during the 1920s and 1930s. More fish appeared not only in the Barents Sea but also off Iceland and Greenland. This warm period reached its peak at the end of the thirties and lasted until roughly 1960, when the waters began turning colder again -- and fisheries resources declined once more. In recent years, the North Atlantic has shown signs of a new period of warming.
