Book excerpt: In 1984, the Northwest Power Planning Council (Council) amended its Fish and Wildlife Program (Program) to include an Action Plan (Section 1500), to give focus and priority directions to various aspects of the Program. Regarding improved hatchery effectiveness, Bonneville Power Administration (BPA) was requested to evaluate ongoing work under 704(h) and submit a workplan to cover future efforts. This report provides concepts for increasing hatchery effectiveness. Additionally, it proposes numerical goals for increased fish production, identifies ways to accomplish them and lists supportive objectives, project schedules, and preliminary budgeting information. Preliminary data from subbasin planning indicates a large additional need for artificially reared salmon and steelhead in the Columbia River Basin. The total need depends upon many factors and this information will be developed and refined as subbasin plans are completed. Recently constructed fish hatcheries are coming on line, and other hatcheries are expected to be prescribed. This workplan is directed at increasing fish propagation at existing facilities, as described in program Section 700. In doing this, four approaches were considered and evaluated: (1) purchasing smolts from commercial resources; (2) building additional but typical hatcheries; (3) modifying existing hatcheries to increase their production with supplemental oxygen; and (4) increasing smolt quality to increase survival, via various supportive actions.
