200750300 - Assessment of Functional Biological Differences Between Natural and Hatchery-Raised Redfish Lake Sockeye Salmon

Sponsor: University of Idaho - Aquaculture Research Institute

Short description: The project will use microarray analysis and quantative PCR to quantify differences in gene expression between natural and hatchery-raised Redfish Lake sockeye salmon. Functional genetic differences will then be correlated with reproductive success.

Location: Mountain Snake province, Salmon subbasin

Budgets: FY08: $199,751 | FY09:

Primary species:
Anadromous: Sockeye: Snake River ESU (endangered)

Quantify differences between Redfish Lake sockeye This research will utilize state-of-the-art advances in molecular genetics whereby the expression of functional genes will be evaluated, quantified, compared, and interpreted. Development of the ability to determine differences in expression of functional (evolutionarily significant) genes from salmon and steelhead stocks is an exciting innovative approach that will likely come to be recognized as the best measure of similarity/dissimilarity between hatchery and wild fish in the future. In addition, samples of fish will be compared to major functional morphological and biochemical (e.g., proximate and fatty acid) differences. These combined techniques will be used to support understanding of observed functional biological similarities and differences. Intermountain Protect biological diversity by benefiting the range of species, stocks, and life-history types in the river. Provide conditions that best fit those natural behavior patterns and river processes that most closely approximate ...
