The fourlZM ~- <br />species are the Colorado squawfish (Ptychocheilus lucius), humpback chub (Gila cypha), ~ <br />bonytail chub (Gila e/egans), and razorback sucker (Xyrauchen texanus). ease <br />of this Executive Summary is to provide a OGR:lJ3lete brief overview of the stu .'

Comments made by the <br />Recovery Program Committee will be incorporated in an Addendum to.this- report <br />. ~Ft~ <br />This study BealS' only ~the biological technical issues. Economic and social issues are <br />beyond the scope of this study and were therefore not included. These issues should <br />be considered in the ultimate site selection process. <br /> <br />The purpose of this study is to evaluate sites in Colorado for a hatchery facility and <br />prepare a feasibility level design that will aid the Recovery Program and the State of <br />Colorado in determining where a site should be located. This study is a unique <br />undertaking as such a facility would provide propagation, research, broodstock hOld;!f. I <br />refugia and public educational opportunities which have not been previously pursu . <br />There are some uncertainties about culture and large scale production techniques. for ~ i., -ffi,'$ <br />these fishes, therefore some assumptions were made as to how this type of facility should ~~ . <br />be operated. <br /> <br />The study was performed by a team of engineers and biologists under the direction of a <br />Technical Advisory Committee (TAC). The TAC is composed of representatives from the <br />CWCB, Colorado Division of Wildlife (CDOW) and the U. S. Fish and Wildlife Service <br />(USFWS). The study team consisted of URS Consultants, Inc., prime contractor and <br />responsible for site evaluation and engineering; Fish Pro, Inc., specializing in fish biology <br />and hatchery design; Bio/West, Inc., specializing in fish biology and fish culture <br />techniques and Leonard Rice Consulting Water Engineers, specializing in the investigation <br />of the water supply aspects of the study. <br /> <br />The primary study tasks are briefly described in the following sections and are as follows: <br /> <br />o Review of Existing Uterature and Facilities <br />o Biological Design and Culture Techniques <br />o Site Identification and Screening <br />o Site Evaluation and Screening <br />o Hatchery Design <br /> <br />1 <br /> <br />,,"..,,',--;~~~-X-<:~,.. :,' _-_".;._~-.-,:~-0..i;;.\I,~,,~~,..;.~....:>:i~__,->_'--~ __,..__,a <br />""-.....~~,..:-.,...".- ---~., <br />
