Location and Contact Information
The Ennis National Fish Hatchery was authorized by Congress in May 1930 and started fish culture operations in July 1933. Ennis National Fish Hatchery is different from other hatcheries. Most hatcheries produce fish of various sizes and then stock these fish in public lakes and streams, providing anglers with hours of fishing fun. Ennis, however, operates as a broodstock hatchery specializing in rearing fish to adult size, then taking the eggs from those fish, incubating them, and shipping them to production hatcheries.
What We Do
The hatchery produces 350,000 fingerling rainbow trout for the state of Montana which are stocked in Montana lakes and reservoirs. After 3 or 4 years, broodstock (the adult fish that provide eggs) are “retired” and stocked into public waters in Montana's urban and youth programs.
Seven different strains of rainbow trout broodstock are cultivated at Ennis National Fish Hatchery. The strains are named for the locations from which they came.
Eagle Lake (California)
Erwin/Arlee Cross (Tennessee)
Fish Lake (Utah)
Harrison Lake (Montana)
