UNIVERSITY OF CALIFORNIA, SANTA CRUZ
This project shall support the operations of Russian River, California fish hatchery facilities owned by the US Army Corps of Engineers (USACE) and operated by the California Department of Fish and Game, by providing genetic data and analysis on fish raised and spawned at these facilities, as well as technical expertise regarding their effects on US Endangered Species Act-listed coho salmon and steelhead both in the Russian River basin and beyond. This project shall build on an existing collaboration between the partner agencies to understand the consequences and effects of producing and rearing salmon and trout at Warm Springs Hatchery (WSH) and Coyote Valley Fish Facility (CVFF), and then releasing them into the Russian River basin.
Expected results include an analysis and evaluation of genotype data for all steelhead spawned 2007-10 at Warm Springs Hatchery (WSH) and a written report describing the analysis and interpretation that will include estimates of inbreeding for the WSH production, estimates of differentiation between hatchery and natural area-origin steelhead, as well as recommendations for hatchery operations in the Russian River Basin, so as to maximize fitness of fish produced. In addition, the project will provide genotype data for all coho salmon that are potential broodstock for the 2010-11 spawning season at WSH and the provision of spawning/breeding matrices derived from the genotype data for all potential broodstock for the 2010-11 coho salmon spawning season.
