M /l/tlJ?ntkl- ~ <br />~_ '1;' (1(;$~idS) <br /> <br />~ <br /> <br />ISSUES AND PERMITS <br /> <br />During the preparation of this study, technical and biological issues have been raised <br />which impacted the site evaluation and design process and which must be considered <br />by the CWCS and the recovery program as the site selection is made and the design of <br />the recovery facility is completed. These issues are briefly described below. An <br />expanded description of these issues can be found in the full text of this study. <br /> <br />Issues <br /> <br />o The need for a hatchery and/or a research facility for the recovery of the <br />endangered fishes; , <br />o The need and level of production for augmentation and for research; <br />o The role of the recovery facility for broodstock holding or refugia; <br />o Determination of the numbers of genetically individual subpopulations for each <br />species; <br />o Use and mix of intensive and extensive fish culture techniques; <br />o Type of hatchery water supply and the impact on fish growth, health, genetics, <br />imprinting, survivability in the wild, and hatchery capital and operation costs; <br />o Hatchery location and proximity to native habitats; <br />o Role of the proposed hatchery and research facility in the overall recovery <br />program; <br />o Responsibility for construction of the hatchery and research facility; <br />o Responsibility for operation of the hatchery and research facility; <br /> <br />Culture Information - Prior to this study, there was no centralized database for information <br />relevant to culture or propagation techniques for the endangered fish, or for the design <br />of a hatchery specifically for these fish. There is much to be learned in this area and the <br />role of the proposed recovery facility in the overall recovery program must be determined <br />as the planning for this facility progresses. <br /> <br />Culture Techniques - The mix of intensive and extensive culture techniques used for the <br />design of the hatchery must be determined. There are significant advantages and <br />disadvantages with each type of culture technique which must be carefully evaluated. <br />The type of fish culture has a great impact on the hatchery design, capital cost and <br />operational cost of the hatchery. The method of fish culture may also have an impact on <br />the genetics of the hatchery fish and their survivability and ability to reproduce in the wild. <br />This is a vary complicated issue, but one which must be resolved for the facility to move <br />forward. <br /> <br />Research goals - <br /> <br />z. <br />
