Coastal steelhead trout : life in the watershed

Creator:: Fitzpatrick, Martin S. and Oregon State University. Sea Grant College Program
Abstract:: Anglers and naturelovers prize steelhead trout for their mystique and power. Oregon has two subspecies of steelhead (so-called because of the metallic appearance of maturing adults) or rainbow trout: a coastal form and an inland form.
Resource Type:: Technical Report
Full Text:: Oregon Department of Fish and Wildlife recog- nizes 295 populations of this subspecies of steelhead

Sex and life stage sensitivity of rainbow trout to xenoestrogens

Creator:: Carlson, David B., 1970-
Abstract:: Numerous natural and anthropogenic chemicals interact with endocrine systems of animals. The most widely studied of these endocrine active chemicals (EACs) are estrogen receptor agonists and antagonists. Because of the many important roles of estrogens in animals, xenoestrogens have the potential to impact environmental health. It has been proposed that...

Distribution, abundance, and emigration of juvenile steelhead (Oncorhynchus mykiss), and analysis of stream habitat in the Steamboat Creek Basin, Oregon

Creator:: Dambacher, Jeffrey M.
Abstract:: Snorkel dive estimates and an inventory of stream habitat of the juvenile steelhead (Oncorhynchus mykiss) population in the Steamboat Creek basin were made in the summers of 1987 and 1988. Emigration was monitored by fish trapping from spring through fall of 1988. Distribution, abundance, and habitat utilization of juvenile steelhead...

Territorial behavior in juvenile steelhead trout (Oncorhynchus mykiss) : how redside shiner (Richardsonius balteatus) influence intraspecific interactions

Creator:: Tinus, Craig A.
Abstract:: Juvenile steelhead are known to associate with shiner groups, though they also compete for food. Steelhead form dominance hierarchies within cohorts and aggressively defend feeding territories against all other fish. This study focused on the differential effect of shiner competition on steelhead of different social standing. Survival of subordinate juvenile...

Proceedings of the Steelhead Management Workshop : June 29, 1994

Creator:: Murtagh, Tom and Oregon. Department of Fish and Wildlife
Abstract:: "This workshop was held to allow both research and management fish biologists to openly discuss the results of several ongoing projects designed to improve the way Oregon manages its steelhead populations." (from the Introduction) The report uses an extended abstract format.

Characteristics of pools used by adult summer steelhead (Oncorhynchus mykiss) in the Steamboat Creek Basin, North Umpqua River, Oregon

Creator:: Baigun, Claudio Rafael Mariano
Abstract:: This study examined features of deep pool (>0.8 m mean depth) used by adult summer steelhead in Steamboat Creek (1991-1992). Steamboat Creek had a heterogenous thermal profile, with some segments exceeding preferred temperature of steelhead. Deep pools were scarce (4% of the total habitat units) and 39% of them were...

1993 Calf Creek migrant trapping results and juvenile steelhead (Oncorhynchus mykiss) emigration estimate

Creator:: Harkleroad, Glenn R.
Abstract:: Trapping migrating steelhead trout smolts was done in the spring and early summer of 1993 as part of the 1990 Umpqua National Forest Land and Resource Management Plan. Calf Creek was monitored to "validate smolt output estimates" and to "determine if changes in habitat quality are occurring." (Introduction)

1991 and 1992 Calf Creek migrant trapping results and juvenile steelhead (Oncorhynchus mykiss) emigration estimate

Creator:: Harkleroad, Glenn R. and La Marr, Timothy J.
Abstract:: Trapping migrating steelhead trout smolts was done in the spring and early summers of 1991 and 1992 as part of the 1990 Umpqua National Forest Land and Resource Management Plan. Calf Creek was monitored to "validate smolt output estimates" and to "determine if changes in habitat quality are occurring." (Introduction)

Impacts of earlier emerging steelhead fry of hatchery origin on the social structure, distribution, and growth of wild steelhead fry

Creator:: Noble, Sandra M. (Sandra Marie)
Abstract:: Newly emerged steelhead fry (Oncorhynchus mvkiss) of hatchery and wild origins were studied in laboratory stream channels and natural streams. Objectives of the study were to determine if and how earlier emerging hatchery fry influence the emigration, realized densities, growth, habitat use, social structure, and activity patterns of localized populations...
