Initial C',NeB <br />production quotas were used as a basic criteria for total bi ass and a target for design <br />which can be related to maximum, average and mini um water flows and various <br />configurations of rearing systems.

This is used <br />as a means of reducing hatchery-induced stress and to help maintain genetic integrity. <br />Holding facilities are designed to house 5,100 adults of all species. The broodstock <br />ponds also incorporate features to function as refugia for these fish. A brood building has <br />been incorporated into the design to accommodate tagging, spawning and recovery of <br />broodstock. <br /> <br />e <br /> <br />.~ <br />~ <br /> <br /> <br />A highly integrated state-of-the-art research facility has been incorporated into the design <br />to satisfy the special requirements of the Recovery Program. Primary research needs <br />focus on genetics, fish health, and population/environment interaction. Research <br />laboratories devoted tq genetics, physiology and pathology are housed together in a <br />building along with support facilities such as a library. photography laboratory, conference <br />and computer rooms.
