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,...
A trawling survey was conducted on Nyanza Gulf, Lake
Victoria, East Africa during March-December 1975 to investigate
association and distribution of the major fish species
and to provide information for management of the fishery.
A total of 139 sites was sampled and all fishes caught were
counted, measured, and weighed....
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...
The objective of this research was to study the effects of increased water temperature characteristic of clearcut watersheds of Pacific coastal streams upon the growth rate of juvenile coho salmon. The natural temperature fluctuations of the stream were used in the study of growth of underyearling fish held in aquariums...
Large numbers of coho salmon (Oncorhynehus kisutch) fry move downstream shortly after emergence from the gravel in many spawning tributaries. In three small coastal streams of Oregon about eight times more juveniles leave the tributaries as newly emerged fry than as smolts one year later. Because these early emigrants comprise...
A technique for estimating gross primary production and respiration of periphyton communities, in situ, in small turbulent streams was developed using a photosynthesis-respiration chamber in a modified "light and dark bottle" method. Trays containing portions of the substrate bearing the benthic community were embedded in the stream, level with the...
Data from the coho salmon migration were examined from three streams of the Alsea Watershed Study, conducted on tributaries to Drift Creek, Oregon, from 1959 through 1973. With the migration season defined as November 1 through May 31, the mean seasonal smolt count was 2022 fish in Deer Creek, 665...
Species interactions and their effect on the use of habitat by benthic fishes were examined in a guild composed of Cottus perplexus, C. rhotheus, and C. beldingi in the Marys River above Philomath, Oregon, and in a constant environment provided by an artificial stream. In the Marys River system, the...
