Technical Abstract: The USDA/ARS National Center for Cool and Cold Water Aquaculture in Leetown, West Virginia is working to integrate molecular genetic technologies into a selective breeding program aimed at the genetic improvement of rainbow trout for aquaculture production efficiency. Our multidisciplinary approach aims to incorporate genome information with respect to disease resistance and stress, growth, and reproductive physiology into our selective breeding program. Selective breeding is based on the hypothesis that sufficient genetic variation exists in broodstock to realize genetic improvement through contributions of superior performing germplasm to future generations. Our associated goal is to develop and transfer improved germplasm and technologies to the aquaculture industry. Our approach to implementing molecular information into our breeding program is outlined under three objectives: 1) development of a genetic map to reveal chromosomal locations affecting traits associated with aquaculture production; 2) use of a candidate gene approach to identify and characterize genes affecting important aquaculture production traits through functional genomic technologies; 3) development of bioinformatic strategies to implement genetic mapping and functional genomic information into a selective breeding program.
