Re i me rs Oregon Department of Fish and Wildl i fe Research Sect ion, Charleston, Oregon April This work was financed in part with Anadromous Fish Act (PL ) funds administered by the National Marine Fisheries Service.

    Reimers PE () The length of residence of juvenile fall Chinook salmon in Sixes River Oregon. Research Reports of the Fish Commission of Oregon 4: 3– In this study, maintaining a constant number of fish was not possible, because the number of fish in the growth study was also used to determine survival. Reimers () observed little change in size of chinook salmon in the Sixes River estuary from June through August, which .

    subyearling Chinook salmon collected from to demonstrated extensive rearing in the estuary. As many as 70% of the fish sampled during July had resided in the estuary from 2 to 6 weeks (Jen Burke, Oregon Department of Fish and Wildlife, Pers. commun). Subyearling Chinook salmon attained 20 to 66% of their fork length while in the estuary. Estimated survival of acoustic-tagged juvenile Chinook salmon and steelhead through the lower Columbia River and estuary in was lowest in the final 50more» Probability of survival was relatively high (>) for yearling and subyearling Chinook salmon from the Bonneville Dam forebay (rkm ) to Three-tree Point (rkm ).
