Yakima River Species Interactions Studies, Annual Report 1994.
Species interactions research was initiated in 1989 to investigate ecological interactions among fish in response to proposed supplementation of salmon and steelhead in the upper Yakima River basin. This is the fifth of a series of annual reports that address species interactions research and pre-facility monitoring of fishes in the upper Yakima River basin. Data have been collected prior to supplementation to characterize the rainbow trout and other fish populations such as steelhead and spring chinook salmon, predict the potential interactions that may occur as a result of supplementation, and develop methods to monitor interactions. Major topics of this report are associated with the life history of rainbow trout, interactions experimentation, and methods for sampling. This report is organized into two chapters followed by seven ''updates'' with a general introduction preceding the first chapter and a general discussion following the last update. An appendix follows the general discussion. This annual report summarizes data collected primarily by the Washington Department of Fish and Wildlife (WDFW) between January 1 and December 31, 1994 in the upper Yakima basin above Roza Dam, however these data were compared to data from previous years to identify preliminary trends and patterns. Major preliminary findings from each of the chapters included in this report are described.
