摘要

Long-term conservation needs of natural salmonid populations and their inherent genetic resources require a reexamination of the role of hatcheries in basin-wide management and conservation strategies. Hatcheries need to be viewed as part of the environmental and ecological landscape to help achieve both conservation and harvest goals. These goals need to be part of a holistic and integrated strategy that combines habitat, hydropower and harvest needs for conserving and managing fishery resources. These strategies, to be successful, must establish short- and long-term goals for both hatchery-propagated and naturally-spawning populations. To ensure that its hatchery programs are best meeting conservation and harvest goals, the U.S. Fish & Wildlife Service (Service) began, in October 2005, a five-year review of 21 salmon and steelhead hatcheries that the Service owns or operates in the Columbia River Basin. The goal of this review is to ensure that Service hatcheries are operated in accordance with best scientific principles, and contribute to sustainable fisheries and the conservation of naturally-spawning populations of salmon, steelhead and other aquatic species. The Service’s review process is modeled after the recent Puget Sound and Coastal Washington Hatchery Reform Project. The report presented here is one of three reports for federally-owned hatcheries that are operated by state agencies in the Snake River basin under the auspices of the Lower Snake River Compensation Plan (LSRCP), a federally-funded program to mitigate for fish losses resulting from the construction and operation of four hydroelectric and transportation dams on the lower Snake River in Washington State.
