The result of changes of water temperature on fisheries is significant. As water temperatures rise and nutrient levels decline, shoals of cold-water-loving small pelagics scatter and descend to depths of 150 to 200 meters, where they are not accessible to traditional surface purse seiners, or they migrate south.
