Scale patterns indicate changes in use of rearing habitat by juvenile coho salmon, Oncorhynchus kisutch, from 1955 to 1984 in the Tenmile Lakes, Oregon

Creator:: Gunnarsdottir, Hugrun
Abstract:: This study was designed to provide information about the juvenile life history of coho salmon, Oncorhynchus kisutch, in the Tenmile Lakes in Oregon by 1) classifying scales of spawning fish and outgoing smolts (1+), 2) assessing the contribution of juvenile life history types to the returns of adults (3₂) and...

A population study of the rainbow trout (Salmo gairdneri) in a Central Oregon stream

Creator:: Osborn, Charles Edwin
Abstract:: The rainbow trout population in Elder Creek, Oregon was studied between June 1965 and November 1966. The physical characteristics of the stream during the summer season were described. Rainbow trout were captured in each of three sections on the stream by electrofishing and were tagged and measured. Population size, mortality,...

Effects of logging on the spawning bed environment in two Oregon coastal streams

Creator:: Ringler, Neil Harrison
Abstract:: The effects of two patterns of logging on the intragravel environment were studied in three Oregon coastal streams between June 1968 and June 1969. The watershed of one stream (Needle Branch) had been clearcut, and that of a second stream (Deer Creek) cut in staggered settings in 1966. A third...

Social interaction between juvenile coho and fall chinook salmon in Sixes River, Oregon

Creator:: Stein, Roy A.
Abstract:: The nature of the interaction between juvenile coho salmon, Oncorhynchus kisutch (Walbaum), and fall chinook salmon, 0. tshawytscha (Walbaum), was studied in Sixes River, Oregon. Seining, snorkeling, and tagging were used to determine distribution and patterns of growth of these two species in the stream environment. Experiments conducted in flowing-water...

The length of residence of juvenile Fall Chinook salmon in Sixes River, Oregon

Creator:: Reimers, Paul E.
Abstract:: This study was designed to provide life history information about juvenile fall Chinook salmon, Oncorhynchus tshawytscha (Walbaum), in a small coastal river by 1) documenting the length of residence of the juveniles throughout the river, 2) exploring several factors possibly influencing their length of residence, and 3) assessing the relative...

An evaluation of the effectiveness of instream structures for steelhead trout rearing habitat in the Steamboat Creek basin.

Creator:: Fontaine, Barbara L.
Abstract:: Several types of instream structures were evaluated for their potential to provide rearing habitat and to increase reach carrying capacity for steelhead trout (Salmo gairdneri). Evaluation was conducted in each season over the course of 1 year. Blast pools created in bedrock glides increased the carrying capacity of stream reaches...

Movements of spawning sockeye salmon in Hidden Creek, Brooks Lake, Alaska

Creator:: Tsunoda, Setsuwo
Abstract:: The movements of a population of adult sockeye salmon (Oncorhynchus nerka) were followed in a small tributary of Brooks Lake, Alaska until spawning was nearly complete in 1963. The objectives of the study were to describe the movements of sockeye salmon on the spawning ground of an entire small stream,...

Changes in size and age at maturity of Columbia River upriver bright fall chinook salmon (Oncorhynchus tshawytscha) : implications for stock fitness, commercial value, and management

Creator:: Beaty, Roy E.
Abstract:: The average size and age of chinook salmon (Oncorhynchus tshawytscha) caught in commercial fisheries along the Pacific Coast of North America have decreased substantially in this century. These declines might be caused in part by changes in size and age at maturity within the stocks contributing to those fisheries. Upriver...
