Seasonal variability in diet and consumption by cottid and salmonid fishes in headwater streams in western Oregon, USA

Creator:: Raggon, Mark F.
Abstract:: Coastal cutthroat trout (Oncorhynchus clarkii clarkii) and cottids (Cottus spp) commonly co-occur in headwater streams in western Oregon. Little is known about the comparative trophic ecology of these species or how they respond to seasonal scarcity of resources. In this study I evaluated the seasonal variability in diets and consumption...

New insights on an old topic : understanding the effects of forest harvest on trout in the context of climate

Creator:: Penaluna, Brooke E.
Abstract:: Studies of the effects of forest harvest on streams and fish have a long history in the Pacific Northwest. Results of this work have prompted development of new forest harvest practices that are more protective of these resources, but the effectiveness of these new practices has not been fully evaluated....

Coastal cutthroat trout : life in the watershed

Creator:: Fitzpatrick, Martin S. and Oregon State University. Sea Grant College Program
Abstract:: Coastal cutthroat trout is one of three cutthroat subspecies found in Oregon. The coastal subspecies, which is closely related to steelhead/rainbow trout and Pacific salmon, displays the most diverse and flexible life history of any of the Oregon salmonids. Coastal cutthroat can be found in streams and rivers from the...

Influence of landscape-scale variables on the age and growth of coastal cutthroat trout Oncorhynchus clarkii clarkii in headwater streams

Creator:: Rehe, William G., Jr.
Abstract:: This thesis provides the first general description of the natural variation in age structure, growth rates, and survival in headwater populations of coastal cutthroat trout Oncorhynchus clarkii clarkii from western Oregon, and a subsequent synthesis of these life-history characteristics across the range of the subspecies. Age, growth, and survival were...

Transferability of models to predict selection of cover by coastal cutthroat trout in small streams in western Oregon, USA

Creator:: Andersen, Heidi V.
Abstract:: We assessed use and selection of cover by coastal cutthroat trout (Oncorhynchus clarkii clarkii) in six headwater streams in three watersheds in western Oregon, USA during the summer low flow period from 1 August and September 30, 2007. We tagged 1037 coastal cutthroat trout (>100 mm) with passive integrated transponder...

A summary of coastal cutthroat trout studies, 1962-1965

Creator:: Bulkley, Ross V., Hansen, David, Skeesick, Delbert G., and Oregon. State Game Commission. Research Division
Abstract:: This report summarizes research on coastal cutthroat trout from the beginning of more intensive studies in 1962 through 1965. Early work involved studies of the growth, survival and catch of hatchery-reared cutthroat in coastal lakes, with a change in 1965 to research in coastal streams and estuaries. Research is continuing,...

Resident cutthroat trout in the central Coast Range of Oregon : logging effects, habitat associations, and sampling protocols

Creator:: Connolly, Patrick John, 1955-
Abstract:: Populations of coastal cutthroat trout, Oncorhynchus clarki clarki, were sampled in 16 headwater streams from logged (20-30 and 40-60 years ago) and unlogged (stand age 125-150 years) basins. Basins logged 20-30 years ago supported the widest range of mean biomass of age 1+ or older cutthroat trout (g/m2) and the...

Distribution and characteristics of an isolated population of coastal cutthroat trout (Oncorhynchus clarki) in streams of Triangle Lake Basin, Oregon

Creator:: Hurley, Steven M.
Abstract:: This research focused on features of a genetically isolated population of cutthroat trout (Oncorhynchus clarki) in the Triangle Lake basin of coastal Oregon. A falls at the outlet of Triangle Lake has blocked upstream migration of trout and anadromous salmonids into the basin. Cutthroat trout were found throughout the six...

On the estimation and application of spatial and temporal autocorrelation in headwater streams

Creator:: Som, Nicholas A.
Abstract:: This collection of three manuscripts serves to improve methods for collecting, interpreting, and utilizing autocorrelated data from headwater stream networks. Each stream network is comprised of linear segments. These segments lie within a unique branching structure that connects the segments via flowing water, and the connectivity provided by water varies...

Catch, migration, growth, and survival of stocked coastal cutthroat trout in Munsel Lake, Oregon

Creator:: Skeesick, Delbert G. and Oregon State Game Commission
Abstract:: The latest phase of a study of the migration, survival, growth, and catch of coastal cutthroat trout, conducted to compare cutthroat trout and rainbow trout. The document describes the geological and biological characteristics of Munsel Creek weir, where the studies were conducted. It also includes graphs of the data and...
