      About Us

      Erwin National Fish Hatchery is a primary National Broodstock Program facility that is responsible for producing ~16 million trout eggs annually. These certified disease free eggs are provided to federal, state, tribal hatcheries, universities, and research centers to support recreational fishing management efforts around the country. The hatchery spawns three strains of rainbow trout (Oncorhynchus mykiss), each with a spawning cycle beginning at different times in the year, and one strain of brook trout (Salvelinus fontinalis).


      The hatchery grounds are open for self-guided tours daily or to schedule a guided tour please call 423.743.4712 to make a reservation.  

      What We Do


      Erwin National Fish Hatchery produces millions of trout eggs per year, shipping the eyed eggs to other facilities to be hatched, grown, and eventually released into public waters for recreational fishing. The hatchery also works with partnering agencies to produce and distribute imperiled freshwater mussels for population recovery efforts in Tennessee and North Carolina. Additionally, we assist partnering agencies with monitoring and distribution of lake sturgeon and monitoring and restoration of native southern Appalachian brook trout populations. 


      Our Organization

      Erwin National Fish Hatchery's primary role exists within the National Broodstock Program, producing millions of certified disease-free eggs to many facilities each year. Outside of trout mitigation, the hatchery participates in freshwater mussel propagation, Southern Appalachian Brook trout restoration, and more. These collaborative efforts combine, working towards the mission of the United States Fish and Wildlife Service as part of the Fish and Aquatic Conservation Program. 

      The Fish and Aquatic Conservation program leads aquatic conservation efforts for the U.S. Fish and Wildlife Service. We are committed to tackling the nation’s highest priority aquatic conservation and recreational challenges to conserve, restore, and enhance fisheries for future generations.
      The National Fish Hatchery System works to support healthy, self-sustaining populations of fish and other aquatic species across the country. Every year we raise and stock over 98 million fish to support the recovery and restoration of imperiled species, recreational fishing, and tribal subsistence...
