research personal and public sources;
acquire information from local, State, and Federal agencies;
conduct a field visit to Dexter National Fish Hatchery (NFH) (later renamed the
Dexter National Fish Hatchery and Technology Center);
visit and interview Propagation Specialists for the Colorado Division of Wildlife
(CDOW) and the U.S. Fish and Wildlife Service (USFWS); and
conduct telephone interviews with key contacts.

.

The following is a description of each approach.

Research Personal and Public Sources

Bio/West personnel have been involved in work with the Colorado River endangered fish
species for over 20 years. A library maintained at the Logan, Utah office, as well as
personal contacts were valuable sources of information. The Utah State University Merrill
library and the College of Natural Resources library were also researched. This search
accounted for most of the library assimilated, which contains 100 literature sources pertinent
to the culture of the Colorado River endangered fish.
