this, barriers have been altered and designed to allow the passage of most fish species, but still impede others. Restoration The intent of lamprey control programs is a safer habitat and a healthier population growth for vulnerable native fish species such as lake trout. The Connecticut Department of Energy and Environmental Protection (DEEP) has taken a different path to this same goal by introducing sea lampreys to freshwater rivers and lakes of the Connecticut River watershed, and providing easier access around dams and other barriers for the lampreys to reach spawning sites high upstream. After preying on larger fish at sea, the adult lampreys migrate up the rivers to spawn, whereupon they quickly die of natural causes and decompose, thus providing a food source for the native freshwater fish species.
