The influence of release strategy and migration history on capture rate of Oncorhynchus mykiss in a rotary screw trap

Creator:: Tattam, Ian A., Ruzycki, James R., Bayley, Peter B., Li, Hiram W., and Giannico, Guillermo R.
Abstract:: Rotary screw traps are used throughout the West Coast of North America to capture emigrating juvenile salmonids. Calibrating the capture efficiency of each trap is essential for valid estimates of fish passage. We released Passive Integrated Transponder (PIT) tagged Oncorhynchus mykiss upstream of a rotary screw trap in the South...

Hepatic heat shock protein 70 and plasma cortisol levels in rainbow trout after tagging with a passive integrated transponder

Creator:: Feldhaus, Joseph W., Heppell, Scott A., Mesa, Matthew G., and Li, Hiram W.
Abstract:: This study examined the potentially stressful effects of tagging juvenile rainbow trout Oncorhynchus mykiss with passive integrated transponder (PIT) tags by measuring short-term (<120-h) changes in plasma concentrations of cortisol and hepatic heat shock protein 70 (hsp70). In a laboratory experiment, plasma cortisol levels were measured in fish before they...

Can humans coexist with fishes?

Creator:: Albins, Mark A., Evans, Allison, Ismail, Gladys, Neilsen, Brian, Pusack, Timothy, Schemmel, Eva, Smith, Wade, Stoike, Susanne, Li, Hiram W., and Noakes, David L. G.
Abstract:: Deciding which textbook to assign to students is often a very difficult decision. A textbook should offer more than just a synthesis of information, it should inspire curiosity, cause one to reflect, and provide a framework for making decisions. Most reviews reflect a single opinion, sometimes based on personal preferences....

Body Size and Growth Rate Influence Emigration Timing of Oncorhynchus mykiss

Creator:: Tattam, Ian A., Ruzycki, James R., Li, Hiram W., and Giannico, Guillermo R.
Abstract:: Juvenile Oncorhynchus mykiss migrate extensively in freshwater during fall. We used individual tagging to study the spatial origin, influences, and outcomes of fall migration on fish that emigrated from summer rearing tributaries during fall (early-emigrants) and those that did not (late-emigrants) in the South Fork John Day River, Oregon. Fall...

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...

Cumulative effects of riparian disturbances along high desert trout streams of the John Day Basin, Oregon

Creator:: Li, Hiram W., Lamberti, Gary A., Pearsons, Todd N., Tait, Cynthia K., Li, Judith L., and Buckhouse, John C.
Abstract:: In a study of cumulative effects of riparian disturbance by grazing on the trophic structure of high desert trout streams, watersheds with greater riparian canopy had higher standing crops of rainbow trout Oncorhynchus mykiss, lower daily maximum temperatures (range, 16-23°C compared with 26-31°C), and perennial flow. Watershed aspect influenced the...

The ecological and cultural importance of a species at risk of extinction, Pacific lamprey

Creator:: Close, David A., Fitzpatrick, Martin S., and Li, Hiram W.
Abstract:: The cultural and ecological values of Pacific lamprey (Lampetra tridentata) have not been understood by Euro-Americans and thus their great decline has almost gone unnoticed except by Native Americans, who elevated the issue and initiated research to restore its populations, at least in the Columbia Basin. They regard Pacific lamprey...
