Inc., specializing in fish biology and life history techniques and Leonard Rice Consulting
Water Engineers, specializing in the investigation of the water supply aspects of the study.

The primary study tasks are briefly described in the following sections and are as follows:

. Review of Existing Literature and Facilities
. Biological Design and Culture Techniques
. Site Identification and Initial Screening
· Site Evaluation and Final Screening
· Recovery Facility Design
· Costs
. Issues and Permits

REVIEW OF EXISTING LITERATURE AND FACILITIES

The purpose of this task was to gather, review and analyze available literature and other
information relevant to fish culture, propagation techniques and facility design for these four
endangered fish species, as there was no centralized data base for culture information prior
to this study. Information was compiled from: 1) personal and public sources identified by
the study team; 2) local, state and federal agencies; 3) a field visit to the USFWS-Dexter
National Fish Hatchery; 4) visits and interviews with propagation specialists from the
USFWS, the CDOW, and the State of Utah; and 5) telephone interviews with key contacts
identified by the T AC and members of the Consultant Team.

The information and data collected from these sources were assembled into five work
productS designed to document and provide ease of access to the available information.
These work products include:

1) an alphabetized list and annotated bibliography of pertinent literature;
2) a catalogued library of pertinent literature;
3) a file of personal communications with key fish culturists;
4) a computerized data retrieval system with key culture data and subject issues; and,
5) a study report which presents pertinent information.

BIOLOGICAL DESIGN AND CULTURE TECHNIOUES

This study task evaluated factors to be used as specific design criteria for a recovery facility
capable of providing for propagation, research, refugia and broodstock facilities for the four
endangered fish species. The hatchery design criteria were developed through the following:

1) agency and study team consultation;
2) interpretation and analysis of available literature and information;
