of propagation activities for production, distribution, and research has been

well documented by Valdez (1985) in his review of hatchery programs for

Threatened and Endangered Fishes of the Colorado River.

Much emphasis has been placed on the development and refinement of cultural

techniques for the species in question. Most of this effort has been

concentrated at Dexter National Fish Hatchery with some additional activity at

Willow Beach National Fish Hatchery. Some limited work has been conducted at

Hotchkiss National Fish Hatchery, Colorado, and at the Utah and Idaho

Cooperative Research Units. Research is currently in progress on the use of

streamside, squawfish grow-out ponds near Grand Junction, Colorado, by the

Service's Colorado River Fishery Project. In addition, streamside propagation

of razorback sucker is being conducted by Colorado River Fishery Project and

Jones Hole National Fish Hatchery personnel in temporary pondS and facilities

constructed on the Ouray National Wildlife Refuge on the Green River near

Vernal, Utah.

An assessment of need and review of potential hatchery sites was completed by

Valentine for the Fish and Wildlife Service in 1983 (Valentine, 1983). That

study included a review of fish needs as projected at that time, a thorough

review of fish cultural requirements for the species, and identification of

potential hatchery sites for additional propagation. Several recommendations

were made, but because there was no clear direction or objectives established

for propagation of these species, no action was taken. The Recovery Program

now provides that direction. Part of the basis for hatchery propagation
