Services
Green Lake National Fish Hatchery (NFH) uses very specific hatchery breeding and rearing protocols to produce disease-free fish and to maintain the genetic integrity of Atlantic salmon. These protocols also help ensure salmon will successfully make the transition from the hatchery environment to the wild. To support recovery, Green Lake NFH raises and stocks approximately 650,000 yearling Atlantic salmon smolts (8” fish) and 200,000+ fall parr (3-5” fish) annually.
About
Green Lake National Fish Hatchery is a large-scale cold water hatchery located in Downeast Maine, established in 1973. Its mission has evolved from providing sport fish to serving as a conservation hatchery dedicated to recovering endangered Atlantic salmon in the Gulf of Maine. It plays a vital role in research and restoration, with three out of every four Atlantic salmon returning to U.S. waters originating from this facility.
