F--California Golden Trout Genetic Monitoring

The USFWS is planning on awarding a contract to UC Davis for the California Golden Trout Genetic Monitoring.The proposed study would use the most current molecular genetic techniques to analyze hybridization levels at specific localities for multiple year samples and determine whether admixture proportions are increasing, decreasing, or stable over time. Using the latest proven techniques (i.e. microsatellite and recently developed Single Nucleotide Polymorphism markers), we will evaluate changes in admixture proportions and genotypes over time. Localities from areas within the South Fork Kern and Golden Trout Creek drainages will be used to determine whether trends are consistent among the two major drainages in the native range. Samples for the proposed project are stored in the Genomic Variation Laboratory tissue archive, with additional samples being collected during the summer 2004 field season by California Department of Fish and Game. EXPECTED RESULTS OR BENEFITS: Results of the proposed research will assist the US Fish and Wildlife Service in developing a Genetics Management Plan for California golden trout and will help target actions necessary for the conservation and recovery of the species so as to avoid its listing. Benefits to the public include economic, recreational, and other non-tangible gains associated with the persistence of California's state freshwater fish within its native habitat. Not to Exceed Amount is $35,000. For questions on this, please contact Kristin Young at 503-872-2827.
