<br />, <br /> <br />, <br /> <br />. <br /> <br />. <br /> <br />Task 2: <br /> <br />Biological Design and Culture Techniques <br /> <br />Objective: <br /> <br />To evaluate factors to be used as specific design criteria for an endangered fish <br />hatchery. <br /> <br />Responsibility: <br /> <br />FishPro and Bio/West will take the lead, with other team members <br />contributing. <br /> <br />Methodology: <br /> <br />1. The following factors will be evaluated: <br /> <br />a, Development of broodstock and refugia population needs: These will be <br />determined through interviews with U.S. Fish and Wildlife Service, <br />Propagation Work Group, Colorado Division of Wildlife, and Utah <br />Division of Wildlife Resources personnel in collaboration with personnel <br />at the Dexter National Fish Hatchery. <br /> <br />b. Capacity for genetic monitoring: This will be discussed and evaluated <br />with U,S. Fish and Wildlife Service propagation specialists and <br />geneticists. <br /> <br />c. Fish health/pathology/Quarantine facilities/disease control: To be <br />evaluated under advisement from state hatchery fish culturists. <br /> <br />d. Fish production: To be based on the three scenarios presented in Table <br />I and on known space and facility requirements from the Willow Beach <br />and Dexter National Fish Hatcheries. <br /> <br />e, Stocking plans: To be evaluated from experience by Utah State <br />University, Arizona Department of Fish and Game, Regions 2 and 6 - <br />U.s, Fish and Wildlife Service. <br /> <br />f. Predator control/avoidance: Similar guidance will be applied to this <br />criteria as used in traditional hatchery operations. <br /> <br />g. Research plans: Research needs perceived by biologists currently <br />involved with the species will be solicited and identified for possible <br />incorporation into a feasibility design, <br /> <br />2. Fish Pro and Bio/West will interact with other members of the project team in <br />evaluating the following factors: <br /> <br />a. Facility fOr controlled spawning: Expertise is available at the Dexter <br />National Fish Hatchery to help us assess this activity. <br /> <br />b. Mortality rates: Personnel at the Dexter and Willow Beach National Fish <br />Hatchery have good information on mortality rates of the endangered <br />fishes in the various life stages under hatchery conditions, <br /> <br />c. Water temperature, water Quality and space requirements: Much <br />information is available in the literature on water temperature; space <br />requirements for the various life stages of each species will be <br />determined in consultation with hatchery and university personnel. <br /> <br />3 <br />
