Youngs Bay salmon rearing and release program. Final Environmental Assessment.

摘要

The Bonneville Power Administration (BPA) proposes to fund a 2-year research program designed to improve the survival of artificially propagated coho salmon (Oncorhynchus kisutch) adults returning to Youngs Bay, Oregon. The aim of the proposed program is to acclimate and rear coho smolts in net pens over winter months and determine whether the number of returning adults can be increased compared to the traditional 2-week acclimation period currently used in Youngs Bay. Overwinter reared coho would be released in the springs of 1993 and 1994. Research information collected from this program would be used to evaluate the effects of overwinter net pen rearing on salmon survival, catch, and straying. BPA has prepared an Environmental Assessment (EA) of the actions that are proposed to implement this Youngs Bay salmon rearing and release program. This EA has been prepared to meet the requirements of the National Environmental Policy Act of 1969 (NEPA) and to be consistent with section 7 of the Endangered Species Act of 1973 (ESA). The EA evaluates the potential effects of net pen acclimation and release activities on threatened or endangered Columbia River Basin salmon stocks, nonlisted salmon stocks that naturally reproduce in Youngs Bay tributaries, water quality, and benthic community populations.
