Since 1881, Colorado Parks & Wildlife fish hatcheries have been dedicated to improving the fish populations of our beautiful state. Today, CPW operates 19 hatcheries that breed, hatch, rear and stock over 90 million fish per year.

Stocking Report. The list below identifies where catchable trout (approximately 10") were recently stocked. Note: The stocking report is updated every Friday during the fishing season and lists waters that were scheduled to be stocked throughout the previous week.
In Colorado, there is a total of 18 hatcheries raising 30+ species of fish which Colorado Parks and Wildlife (CPW) operate. Twelve of these hatcheries are cold water facilities, two are warm water facilities, two are cold and warm water, and two are USFWS hatcheries. [3]

The Fish Research Hatchery produces, cultures and maintains Hofer brood and Harrison Lake brood rainbow trout. CPW-led researchhas shown that these specific sub-species of rainbow trout have shown to be more resistant to the parasite that causes whirling disease than other sub-species. The results from this research have now been integrated into C...
The Fish Research Hatchery hatches and rears greenback cutthroat brood stock (mature fish used for breeding) for the Poudre Rearing Unit. Greenback cutthroat trout are listed as threatened on the state list. CPW's recovery plan for the species request a certain number of fish each year for recovery projects (reclamation and restoration) and recreat...
Along with CPW researchers and biologists, the Fish Research Hatchery is spawning Roan Creek Cutthroat trout in the wild. Eggs gathered in the wild are brought to the FRH where technicians can keep families separated until the genetics of each family is determined. FRH only transfers the purest strain of Roan Creek fish to the Glenwood Springs Fish...
Colorado’s hatchery system produces millions of rainbow trout annually. As new strains of rainbow trout, for example those resistant to whirling disease, are incorporated into the hatchery system, new challenges to rearing these fish arise. Along with CPW researchers, the FRH has been conducting experiments designed to optimize rainbow trout produc...

Feb 28, 2019 · Each year, Colorado Parks & Wildlife (CPW) breeds over 90 million fish in 19 hatcheries across the state. These fish are then distributed to waters around Colorado. There are two main reasons for fish stocking — one is to provide more fish for anglers to catch, and another is to help boost populations of threatened and endangered native ...
