To provide such information, the National Marine Fisheries Service, under contract to the CofE, conducted a 5-year study relatively constant over the entire downstream migration. state of knowledge about juvenile salmonid movement and passage through culverts at road crossings. This report summarizes the findings of the literature review. The conclusion of this literature review is that stream dwelling salmonids are often highly mobile. Upstream movement was observed in nearly all.

The Yukon River is the fourth largest river in North America, yet the ecology of its fishes has not been well described. During the spring and summer ofwe sampled the downstream. The focus of this study was to evaluate the downstream migrations of juvenile salmonids and other fishes in the upper Yukon River.

Other than work on adult salmon (e.g., JTC, ), there has been only one study of fish migra-tions on the Yukon River, and it was qualitative in nature (Walker, ).

This basic life history information is. and age at which juvenile salmonids in the Taku River migrate from upriver spawning areas into the lower river and to deter-mine the amount of time they spend there before going to sea. Previous studies have examined downstream migrations of ju-venile salmonids in the Taku River (Meehan and Siniff ; Heifetz et al.

The South Santiam trap was also located on private property near the town of Cascadia and was ~10 km upstream of Foster Reservoir (at full pool). The South Fork McKenzie trap was located just downstream from the USGS gauging station (station ) and was ~1 km upstream of Cougar Reservoir (at full pool).

The proliferation of introduced northern pike in Southcentral Alaska is an urgent fishery management concern because pike are voracious predators that prey heavily on juvenile salmonids. Eradication of pike is not possible in connected freshwater networks, so managers must develop control methods that reduce pike populations to less destructive.

Juvenile steelhead are indistinguishable from juvenile rainbow trout during the first few years of their life. The oldest known-aged steelhead in Alaska is an year fish from the Situk River which spent 5 years rearing in freshwater followed by 6 years in the ocean; the number of times this fished spawned is unknown.

Objectives In this report we present estimated survival of acoustic-tagged juvenile yearling Chinook salmon (CH1), steelhead (STH), and subyearling Chinook salmon (CH0) downstream of Bonneville Dam as they migrated seaward through the Columbia River.
