Effects of routine handling and tagging procedures on physiological stress responses in juvenile chinook salmon

Creator:: Sharpe, Cameron S., Thompson, Daniel A., Blankenship, H. Lee, and Schreck, Carl B.
Abstract:: Juvenile chinook salmon Oncorhynchus tshawytscha were subjected to handling and tagging protocols typical of normal hatchery operations and monitored for their physiological response to stress. Treatments included coded-wire-tagging, counting, ventral fin clipping, adipose fin clipping, and a procedure simulating a pond split. Treatment fish were also subjected to a standardized...

Characterization of the physiological stress response in lingcod

Creator:: Milston, Ruth H., Davis, Michael W., Parker, Steven J., Olla, Bori L., Clements, Shaun, and Schreck, Carl B.
Abstract:: The goal of this study was to describe the duration and magnitude of the physiological stress response in lingcod Ophiodon elongatus after exposure to brief handling and sublethal air stressors. The response to these stressors was determined during a 24‐h recovery period by measuring concentrations of plasma cortisol, lactate, glucose,...

Potential classification of sex and stage of gonadal maturity of wild white sturgeon using blood plasma indicators

Creator:: Webb, Molly A. H., Feist, Grant W., Foster, Eugene P., Schreck, Carl B., and Fitzpatrick, Martin S.
Abstract:: Twenty-two steelhead trout (Salmo gairdneri) containing coded wire tags (CWT's) were captured in gillnets fished by the Oshoro-Maru in the Gulf of Alaska and along 180 during 1982-85. These fish originated from North American streams and hatcheries in British Columbia, Idaho, and Washington. One fish was age 0.1, 16 were...

The effects of electroshock on immune function and disease progression in juvenile spring chinook salmon

Creator:: VanderKooi, Scott P., Maule, Alec G., and Schreck, Carl B.
Abstract:: Although much is known about the effects of electroshock on fish physiology, consequences to the immune system and disease progression have not received attention. Our objectives were to determine the effects of electroshock on selected immune function in juvenile spring chinook salmon Oncorhynchus tshawytscha, the mechanism of any observed alteration,...

Effects of juvenile steelhead on juvenile chinook salmon behavior and physiology

Creator:: Kelsey, D. A., Schreck, Carl B., Congleton, J. L., and Davis, L. E.
Abstract:: Experiments were designed to determine whether and how steelhead Oncorhynchus mykiss affect chinook salmon O. tshawytscha when the two species are confined together. In a behavioral experiment, we observed groups of juvenile chinook salmon and steelhead together and groups of chinook salmon alone to determine whether the steelhead were aggressive...

Columbia River salmonid outmigration : McNary Dam passage and enhanced smolt quality : completion report, April 1, 1985

Creator:: Schreck, Carl B. and Li, Hiram W.
Abstract:: We evaluated the effects of the McNary Dam transportation system on emigrating fall and spring chinook smolts using physiological indices of stress (e.g., plasma cortisol, hepatic glycogen, leucocrit, interrenal cell nuclear diameter) and performance tests (e.g., saltwater challenge, secondary stress challenge, disease resistance). We also conducted controlled experiments in a...

A comparison of the behavior and survival of juvenile coho salmon (Oncorhynchus kisutch) and steelhead trout (O. mykiss) in a small estuary system

Creator:: Clements, Shaun, Stahl, Thomas, and Schreck, Carl B.
Abstract:: We used radio and acoustic telemetry to study the behavior and survival of wild steelhead trout (Oncorhynchus mykiss) and hatchery coho salmon (Oncorhynchus kisutch) and steelhead outmigrants in a small coastal estuary during two years. Survival was generally low for hatchery fish but more variable, both within and between years,...

Effect of short-term decrease in water temperature on body temperature and involvement of testosterone in steelhead and rainbow trout, Oncorhynchus mykiss

Creator:: Miura, Go, Munakata, Arimune, Yada, Takashi, Schreck, Carl B., Noakes, David L. G., and Matsuda, Hiroyuki
Abstract:: The Pacific salmonid species Oncorhynchus mykiss is separated into a migratory form (steelhead trout) and a non-migratory form (rainbow trout). A decrease in water temperature is likely a cue triggering downstream behavior in the migratory form, and testosterone inhibits onset of this behavior. To elucidate differences in sensitivity to water...

Pre-spawning migration of adult Pacific lamprey, Entosphenus tridentatus, in the Willamette River, Oregon, U.S.A.

Creator:: Clemens, Benjamin J., Mesa, Matthew G., Magie, Robert J., Young, Douglas A., and Schreck, Carl B.
Abstract:: We describe the migration distances and timing of the adult Pacific lamprey, Entosphenus tridentatus, in the Willamette River Basin (Oregon, U.S.A.). We conducted aerial surveys to track radio-tagged fish upstream of a major waterfall and hydropower complex en route to spawning areas. We detected 24 out of the 43 fish...
