This book was released on 2005 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: White sturgeon in the Hells Canyon reach (HCR) of the Snake River are of cultural importance to the Nez Perce Tribe. However, subsistence and ceremonial fishing opportunities have been severely limited as a result of low numbers of white sturgeon in the HCR. Hydrosystem development in the Columbia River Basin has depressed numbers and productivity of white sturgeon in the HCR by isolating fish in impounded reaches of the basin, restricting access to optimal rearing habitats, reducing the anadromous forage base, and modifying early life-history habitats. Consequently, a proactive management plan is needed to mitigate for the loss of white sturgeon production in the HCR, and to identify and implement feasible measures that will restore and rebuild the white sturgeon population to a level that sustains viability and can support an annual harvest. This comprehensive and adaptive management plan describes the goals, objectives, strategies, actions, and expected evaluative timeframes for restoring the white sturgeon population in the HCR. The goal of this plan, which is to maintain a viable, persistent population that can support a sustainable fishery, is supported by the following objectives: (1) a natural, stable age structure comprising both juveniles and a broad spectrum of spawning age-classes; (2) stable or increasing numbers of both juveniles and adults; (3) consistent levels of average recruitment to ensure future contribution to reproductive potential; (4) stable genetic diversity comparable to current levels; (5) a minimum level of abundance of 2,500 adults to minimize extinction risk; and (6) provision of an annual sustainable harvest of 5 kg/ha. To achieve management objectives, potential mitigative actions were developed by a Biological Risk Assessment Team (BRAT). Identified strategies and actions included enhancing growth and survival rates by restoring anadromous fish runs and increasing passage opportunities for white sturgeon, reducing mortality rates of early life stages by modifying flows in the HCR, reducing mortality imposed by the catch and release fishery, augmenting natural production through translocation or hatchery releases, and assessing detrimental effects of contaminants on reproductive potential. These proposed actions were evaluated by assessing their relative potential to affect population growth rate and by determining the feasibility of their execution, including a realistic timeframe (short-term, mid-term, long-term) for their implementation and evaluation. A multi-pronged approach for management was decided upon whereby various actions will be implemented and evaluated under different timeframes. Priority management actions include: Action I- Produce juvenile white sturgeon in a hatchery and release into the management area; Action G- Collect juvenile white sturgeon from other populations in the Snake or Columbia rivers and release them into the management area; and Action D- Restore white sturgeon passage upriver and downriver at Lower Snake and Idaho Power dams. An integral part of this approach is the continual monitoring of performance measures to assess the progressive response of the population to implemented actions, to evaluate the actions efficacy toward achieving objectives, and to refine and redirect strategies if warranted.

This book was released on 1987 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1996 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author reports on progress from April 1994 through March 1995 of research on white sturgeon in the lower Columbia River. The study began in July 1986 and is a cooperative effort of federal, state and tribal fisheries entities to determine the (1) the status and habitat requirements, and (2) the effects of mitigative measures on productivity of white sturgeon populations in the lower Columbia River. This report describes activities conducted during the third year of this contract's second phase. Information was collected, analyzed, and evaluated on sub-adult and adult life histories, population dynamics, quantity and quality of habitat, and production enhancement strategies. The report is divided into sections that evaluate success of developing and implementing a management plan for white sturgeon; evaluate growth, mortality, and contributions to fisheries of juvenile white sturgeon transplanted from areas downstream; describe the life history and population dynamics of sub-adult a nd adult white sturgeon; define habitat requirements for spawning and rearing of white sturgeon and quantify the extent of habitat available; describe reproductive and early life history characteristics of white sturgeon; and quantify physical habitat used by spawning and rearing white sturgeon in the free-flowing portion of the Columbia River.

Available in PDF, EPUB and Kindle. Book excerpt: Bonneville Power Administration (BPA) is proposing to fund the White Sturgeon Mitigation and Restoration in the Columbia and Snake Rivers Upstream from Bonneville Dam Project. The project proposes to continue to carry out harvest monitoring and stock status updates coordinated with fisheries management planning, annual young-of-the year recruitment indexing, research, experimental artificial propagation, and transport of white sturgeon to less densely populated areas of the river(s). Additionally, release of hatchery-reared juveniles is proposed to evaluate release strategies. Actions will take place in the following Columbia River mainstem reaches: Bonneville, The Dalles, John Day, and McNary Reservoirs; Hanford Reach, as well as the Wanapum and Rock Island Reservoirs; and the following Snake River mainstem reaches: Ice Harbor, Lower Monumental and Little Goose Reservoirs. Spawning and rearing are undertaken at established hatcheries at McNary Dam and also the Abernathy Fish Technology Center. BPA has prepared an Environmental Assessment (EA) (DOE/EA-1367, April 2003) evaluating the proposed project. Based on the analysis in the EA, BPA has determined that the proposed action is not a major Federal action significantly affecting the quality of the human environment, within the meaning of the National Environmental Policy Act (NEPA) of 1969. Therefore, the preparation of an Environmental Impact Statement (EIS) is not required, and BPA is issuing this Finding of No Significant Impact (FONSI).

This book was released on 1993 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report on our progress from April 1992-March 1993 in research on white sturgeon in the lower Columbia River. The study began in July 1986 and progress through 1992 was summarized in a comprehensive report in 2 volumes (Beamesderfer and Nigro 1993a, 1993b). This report details activities during the first year of Phase II of this sturgeon research. In Phase I, we assessed the status and habitat requirements of the white sturgeon populations in the Columbia River downstream from McNary Dam. Phase II will examine the effects on white sturgeon productivity of mitigative measures recommended in Phase I. The status and habitat requirements of white sturgeon populations upstream from McNary Dam will also be examined in Phase II. The study is a cooperative effort by the Oregon Department of Fish and Wildlife, Washington Department of Fisheries, U.S. Fish and Wildlife Service, and National Marine Fisheries Service. Work during the past year has focused on: (1) analysis of results of limited sampling conducted in 1992, (2) submission of Phase I results to the peer-review literature to ensure widespread dissemination, clarity of presentation, and credibility of findings, and (3) preparations for additional field work in 1993. In report sections A to D, each agency reports 1992 results if applicable and the current status of manuscripts. Results of field work conducted in 1993 will be reported in the 1994 annual report.
