Creator:: Everest, Fred H. and Oregon State Game Commission
Abstract:: Project AFS 31 Final report The final report of a study to determine whether discrete races of summer steelhead races exist in the Rogue River, and if so to isolate each race in terms of life history and ecological behavior, including such points as time of entry, seasonal positioning and...

Full Text:: ECOLOGY AND MANAGEMENT OF SUMMER STEELHEAD IN THE ROGUE RIVER

Creator:: Cowgill, Ralph
Abstract:: Mimeographed copy of a report, presumably to the Oregon State Game Commission. Includes maps and original b+w photographs of Rogue River dams, fishways, and fishing in the late 1920s. The author was extremely frank about the issues of the day, particularly law enforcement issues.

Creator:: Ohms, Haley
Abstract:: The evolution and maintenance of multiple phenotypes within populations is an interesting evolutionary and ecological question, and is becoming increasingly important for the restoration and conservation of partially migratory species. In particular, why individuals adopt a particular phenotype has been the focus of numerous research efforts. In the partially migratory...

Creator:: Tattam, Ian A.
Abstract:: Understanding seasonal changes in growth, survival, and movement rates is crucial to salmonid management. These life history characteristics provide a context for evaluation of management actions. We evaluated the life history of individually marked Oncorhynchus mykiss gairdneri in the South Fork John Day River basin in Northeastern Oregon. This thesis...

Full Text:: reproducing populations of summer steelhead and redband trout (both O. mykiss). Summer steelhead

Creator:: White, Seth Michael
Abstract:: I examined the relative roles of biotic and abiotic factors in structuring redband trout Oncorhynchus mykiss distributions in the South Fork John Day. I first examined the relationship between the biological traits of the fish assemblage and riparian-geomorphic features in context of prevailing theories of stream ecology stemming from the...
