This is extremely important to hatchery <br />operations, especially for a hatchery dedicated to holding and propagation of endangered <br />species. Therefore groundwater supplies were given higher point values than surface <br />water supplies. The endangered fishes also require warm water for spawning and <br />growth. Naturally occurring warm water supplies were rated higher, and offer a significant <br />cost advantage over heating cold water supplies. <br /> <br />A matrix was developed which tabulates the evaluation factors and subfactors, allowable <br />rating points and the site evaluation scores for each of the sites. The matrix is presented <br />as Table 4. Site scores for each evaluation factor are totaled at the bottom of the matrix. <br />Sites which are most preferred and best meet the evaluation factors have higher scores. <br /> <br />HATCHERY DESIGN <br /> <br />The purposes of the hatchery/research facility are to meet the endangered fish recovery <br />goals determined by the CWCB staff, specifically: augmentmion of native populations, <br />refugia and broodstock holding and to provide facilities for research. During the initial <br />development of the scope of work,' the CWCB staff determined a range of hatchery <br />production goals for each species of 150,000, 300,000 and 600,000 fish per year. This <br />production was estimated to meet the needs of augmentation and research. The CWCB <br />staff selected a range of production goals because of the uncertainty at this time of the )< <br />actual needs of the recovery program. <br />. ::;ii ~ <br /> <br />7 <br /> <br />:i-:. -,_k-~';'~-~~:'~...-;,._.;-....:; -_ <br /> <br />. ~ _ ;r~t~&~ii~~7::,:.:~_-~._~_." <br /> <br />. ::"'...,j"",:..~_........,:;,;-.- ~"..:..:o-:-;, ~~...._ ...-:";-. _ ~;.<~.~_: .~,>-_ <br /> <br />.. _ . l <br />~.;;',',...>~_:.....;;.:.;:..~...c <br />
