We report progress of research on white sturgeon in the lower Columbia River from April 1993 through March 1994 .
This study began in July 1986 and is a cooperative effort of federal, state, and tribal fisheries entities to determine the status and habitat requirements and the effects of mitigation effort on productivity of white sturgeon populations in the lower Columbia River.
Work conducted through 1992 examined the status and habitat requirements of white sturgeon populations downstream from McNary Dam (Phase I). In 1993, we began Phase II, to examine the effects of mitigation measures recommended in Phase I. We are also examining the status and habitat requirements of white sturgeon populations upstream, between McNary and Priest Rapids Dams on the mainstem Columbia and lower Snake River, as part of Phase II.
This report describes activities conducted during the second year of Phase II. Information was collected, analyzed, and evaluated on subadult and adult life histories, population dynamics, quantity and quality of habitat, and production enhancement strategies. An abstract is provided at the beginning of sections A-F to summarize the results of work contributed by each agency.
