Abundance, movements, and feeding habits of harbor seals, Phoca vitulina, at Netarts and Tillamook Bays, Oregon

Creator:: Brown, Robin F. and Mate, Bruce R.
Abstract:: Patterns of seasonal abundance of harbor seals at Netarts and Tillamook Bays, Oregon, were documented by recording numbers of seals hauling out on tidally exposed sand flats in both bays. Harbor seal abundance at Tillamook Bay peaked during pupping (May-June) and molting (August) periods, while peak abundance at Netarts Bay...

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...

Effects of transportation on outmigration and fitness for marine survival of Columbia River salmon : completion report, October 1980

Creator:: Schreck, Carl B.
Abstract:: It is current practice to transport juvenile anadromous salmonids in transplantation and to help them bypass dams. Essentially nothing is known about the effects that transportation could have on the ability of the fish to outmigrate and be fit for survival in the marine environment. Procedures involved in transporation subject...

Costs and Efficacies of Methods for Controlling Bird Damages to Grapes

Creator:: deCalesta, David S.
Abstract:: Grape growers seeking to protect their grapes from bird depredations have no economic guidelines for selecting one or more of several control alternatives. Many growers are not aware of the cost of applying the various control techniques, nor do they know how effective these techniques are in preventing damage to...

Interactions between grizzly bears and hikers in Glacier National Park, Montana

Creator:: Jope, Katherine Louise McArthur
Abstract:: Behavior of grizzly bears (Ursus arctos) toward people was studied by examining hikers' reports of grizzly bear observations and by intensively observing grizzlies in an area of Glacier National Park that was heavily used by day-hikers. Of concern were the apparent habituation of grizzly bears to people in the study...

Influences of environmental acidification on salmonid reproduction

Creator:: Weiner, Gary S.
Abstract:: Reproduction of salmonid fishes in acidic water was studied using the rainbow trout (Salmo gairdneri). Adult trout were exposed to various levels of hydrogen ion (pH levels 4.5, 5.0, 5.5, and control [6.5 to 7.1]) during the final 6 weeks of reproductive maturation. Reduced survival rates of the progeny of...
