Book Description
Measure 804(e)(8) of the Northwest Power Planning Council (NPPC) Fish and Wildlife Program states that Bonneville Power Administration (BPA) ''shall fund research to determine the impacts of development and operation of the hydroelectric power system on sturgeon in the Columbia River Basin ... '' In June 1985, BPA sponsored a workshop to define and list in priority order research needs in the basin (Fickeisen 1985a). In December 1985, BPA submitted a research program implementation plan (Fickeisen 1985b) to the NPPC. The purpose of the plan is to provide guidance for conducting research necessary to address four objectives identified by regional fishery interests for protecting, mitigating and enhancing white sturgeon populations in the Columbia River basin. The plan's objectives are: (1) Assess the current status of Columbia River basin white sturgeon stocks. (2) Provide the basis to evaluate the need for protection, mitigation and enhancement of white sturgeon in the Columbia River system. (3) Provide information that can be used to evaluate potential methods of protection, mitigation and enhancement of existing stocks. (4) Provide tools to assess the effectiveness of protection, mitigation and enhancement efforts.

Book Description
This is the final report for research on white sturgeon Acipenser transmontanus from 1986--92 and conducted by the National Marine Fisheries Service (NMFS), Oregon Department of Fish and Wildlife (ODFW), US Fish and Wildlife Service (USFWS), and Washington Department of Fisheries (WDF). Findings are presented as a series of papers, each detailing objectives, methods, results, and conclusions for a portion of this research. This volume includes supplemental papers which provide background information needed to support results of the primary investigations addressed in Volume 1. This study addresses measure 903(e)(1) of the Northwest Power Planning Council's 1987 Fish and Wildlife Program that calls for ''research to determine the impact of development and operation of the hydropower system on sturgeon in the Columbia River Basin.'' Study objectives correspond to those of the ''White Sturgeon Research Program Implementation Plan'' developed by BPA and approved by the Northwest Power Planning Council in 1985. Work was conducted on the Columbia River from McNary Dam to the estuary.

Book Description
We report on our progress from April 1988 through March 1989 on determining the status and habitat requirements of white sturgeon populations in the Columbia River downstream from McNary Dam. Highlights of results of our work in the Dalles and Bonneville reservoirs are: using setlines, we caught 1,586 sturgeon in The Dalles Reservoir and 484 sturgeon in Bonneville Reservoir in 1988. Fork length of fish caught ranged from 34 cm to 274 cm. Of the fish caught we marked 1,248 in The Dalles Reservoir and 341 in Bonneville Reservoir. Of the fish marked in 1988, we recaptured 82 in The Dalles Reservoir and none in Bonneville Reservoir. We recaptured 89 fish marked in 1987 in The Dalles Reservoir. Anglers recaptured 35 fish marked in 1988 and 16 fish marked in 1987 in The Dalles Reservoir. Anglers recaptured 2 sturgeon marked in 1988 in Bonneville Reservoir. Individual papers were processed separately for the data base.

Book Description
This multi-authored symposium volume addresses the vulnerability and continuing decline of numerous sturgeon species and stocks and the intense efforts to manage and protect them. It presents timely, accessible, and directly applicable biological and ecological research leading to more effective conservation and management of North American salmon. Written by scientists, resource managers, and electric utility industry personnel with a shared interest in sturgeon biology and ecology, management, and protection, this book includes life history characteristics relevant to population dynamics, viability, and persistence; upstream and downstream migratory behavior, habitat requirements and local movement; passage technologies; and conservation management and stock enhancement. Most major sturgeon species in America are covered, including shortnose, Atlantic, Gulf, lake and green sturgeon.

Book Description
We report on our progress from April 1990 through March 1991 on determining the status and habitat requirements of white sturgeon populations in the Columbia River downstream from McNary Dam. The study is a cooperative effort by the Oregon Department of Fish and Wildlife (ODFW), Washington Department of Fisheries (WDF), US Fish and Wildlife Service (FWS) and National Marine Fisheries Service (NMFS). Study objectives addressed by each agency are to describe the life history and population dynamics of subadults and adults between Bonneville and McNary dams and evaluate the need and identify potential methods for protecting, mitigating and enhancing populations downstream from NcNary Dam; to describe the white sturgeon recreational fishery between Bonneville and McNary dams, describe reproductive and early life history characteristics downstream from Bonneville Dam and describe life history and population dynamics of subadults and adults downstream from Bonneville Dam; to describe reproduction and early life history characteristics, define habitat requirements for spawning and rearing and quantify extent of habitat available between Bonneville and McNary dams; and to describe reproduction and early life history characteristics, define habitat requirements for spawning and rearing and quantify extent of habitat available downstream from Bonneville Dam. Our approach is to work concurrently downstream and upstream from Bonneville Dam. Upstream from Bonneville Dam we began work in the Dalles Reservoir in 1987 and expanded efforts to Bonneville Reservoir in 1988 and John Day Reservoir in 1989. Highlights of results of this work in the Dalles, Bonneville and John Day reservoirs are included in the four pages included in this report.
