Ennis National Fish Hatchery
Rainbow Trout
Egg, Fingerling, and Broodstock Production
December 30, 2003
Project Description
Ennis NFH is a highly technical, state-of -the-art hatchery that is the largest broodstock facility in the U.S. Fish and Wildlife Service hatchery system. The hatchery annually produces over 20 to 30 million eyed rainbow trout eggs, which are shipped to federal, state, provincial, and tribal hatcheries, research facilities, and universities in over thirty states and provinces. In addition the hatchery provides genetically viable broodstock eggs for state and private hatcheries in the process of developing future rainbow trout broodstock from multiple strains and conducts research into improved hatchery broodstock and spawning technology. Quality fingerling production for conservation agreements to assist with restoration and recovery, ranges from 400,000 to 500,000 fish annually. Many of these fish are stocked into Hebgen, Ruby, and Clark Canyon Reservoirs for Montana Fish Wildlife and Parks in exchange for grayling restoration projects. Each year over 30,000 pounds of retired broodstock are liberated into “Kids” and urban ponds for outreach and education
