We tested the hypothesis that spawning-bed enhancement increases survival and growth of chinook salmon (Oncorhynchus tshawytscha) embryos in a regulated California stream with a gravel deficit. We also examined how 12 physical parameters correlated within spawning sites and how well they...

We studied microbial communities in the water column during the fall 2002 Chinook salmon (Oncorhynchus tshawytscha) run on the Feather River in northern California. We quantified culturable heterotrophic bacteria, live/dead bacteria, and Aeromonas spp. bacteria in the water column....

Accurate estimates of escapement by adult anadromous salmonids are difficult, especially in large, multistock river systems. We used radiotelemetry and a fishery reward program to calculate escapement, harvest, and unaccounted for loss rates for 10 498 adult chinook salmon (Oncorhynchus...

Provides evidence that the Yolo Bypass, the primary floodplain of the lower Sacramento River provides better rearing and migration habitat for juvenile chinook salmon than adjacent river channels. Improved growth rates in the floodplain; Survival indices for coded-wire-tagged groups; Prediction...
