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 tational 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
