Description:

Size separation of juvenile Pacific salmonids Oncorhynchus spp. is important for the effective management of Columbia and Snake River systems and the fish transportation program. Studies continued in 2000 at Ice Harbor Dam on the Snake River and at McNary Dam on the Columbia River to improve wet-separation techniques for implementation in juvenile bypass facilities at hydroelectric facilities. The effects of eight treatments on separation efficiency, separator exit efficiency (a measure ofresidence time in the separator unit), and fish condition (descaling) were evaluated using river-run juvenile salmonid migrants over the spring migration period at the Ice Harbor Dam high-velocity flume (HVF) test separator facility. Treatment factors included combinations of water velocity (1 mis and 2 mis), wave height (high and low), and separation bar array orientation (angled or parallel). Fish were separated by species into small and large fish groups (fork length (FL) <180 mm or 2::180 mm), using bars spaced 1 7 mm apart.
