Passage Route Survival and Behavior of Juvenile Salmon at Priest Rapids Dam, Columbia River, WA
… added anthropogenic pressure to Columbia River salmon populations. Juvenile salmon that pass through powerhouse turbines at large hydropower dams display higher mortality rates than salmon passing through alternative routes; thus at Priest Rapids Dam, a top-spill fish bypass was constructed as a …

The Ecology of Parafluvial Ponds on a Salmon River
… of the Kwethluk River, I observed thousands of juvenile salmon apparently trapped by surface disconnection of the ponds from the river. I was interested in whether the salmon could survive until flooding reconnected the ponds to the river. I sampled ponds along the river corridor to describe …

EPIBENTHIC INVERTEBRATES AND JUVENILE CHUM SALMON (ONCORHYNCHUS KETA) PREY AVAILABILITY ALONG AN ECO-ENGINEERED SHORELINE: A CASE STUDY AT THE SEAWALL IN SEATTLE, WASHINGTON
… shallow water habitat available to out-migrating juvenile salmon (Oncorhynchus spp.) by deepening nearshore water and shading the shoreline environment. Previous studies along Seattle’s Elliott Bay waterfront have shown that common prey of migrating juvenile salmon, small epibenthic crustaceans …

Resource use and life history patterns of juvenile Coho and Chinook salmon in an Alaskan estuary
… valuable nursery grounds for anadromous Pacific salmon supplying diverse habitats, quality foraging grounds, and a transition between freshwater and saltwater environments. By providing alternative rearing habitats, estuaries may also bolster the life history diversity expressed in a population, …

Hydraulic and biological aspects of fish passes for dams
… achieved through a novel experiment of testing juvenile salmon in a scale model fish-passes with a range of small structures including vertical slots, orifices, weirs and combinations of all three. Direct comparisons of the efficiency of each type of fish pass in terms of upstream migration. Two …

Wake characteristics associated with logjams to inform river restoration
… benefits, including generating pools for salmonid spawning, propagule retention sites, and increasing biodiversity. Due to these benefits, engineered logjams are being placed back into rivers, especially in the Pacific Northwest of the U.S., to promote salmonid populations. Riverine …

Predicting how the juvenile life-stages of anadromous Atlantic salmon Salmo salar influence their migration phenology and marine survival.
Atlantic salmon, Salmo salar (hereafter ‘salmon’), is a species of high commercial, recreational, and cultural importance. Native to rivers of both sides on the North Atlantic basin, this species has experienced dramatic population declines since the 1970s. The reasons for this phenomenon are …
