Life history of the snake prickleback Lumpenus sagitta Wilimovsky, 1956

Creator:: Tresierra-Aguilar, Alvaro
Abstract:: Data are presented on the life history of snake pricklebacks, Lumpenus sagitta, collected in Yaquina Bay, Oregon, from June 1977 to October 1978. Specimens were collected primarily by beach seine from four sampling sites in the bay. Snake pricklebacks feed on algae (mainly genus Enteromorpha), on polychaeta (mainly genus Neoamphitrite),...

Ecology of woody riparian vegetation in tributaries of the Upper Grande Ronde River basin, Oregon

Creator:: Lytjen, Danna J.
Abstract:: Two studies on Catherine Creek and Meadow Creek of the Upper Grande Ronde River basin, quantified several physical and biotic influences on woody riparian community composition and structure. The Catherine Creek study examined the association of woody riparian species with elevational and geomorphic gradients. The Meadow Creek study examined the...

Effects of chlorinated biologically stabilized kraft mill effluent on the mortality and growth of Coho salmon

Creator:: Steil, Deborah L.
Abstract:: Ninety-six hour acute toxicity bioassays were employed to determine the tolerance of juvenile coho salmon to chlorinated stabilized kraft mill effluent (SKME). In addition the effect of chlorinated SKME on the growth of juvenile coho salmon in six and ten day experiments was studied. Results of the acute toxicity tests...

Conservation and spatial use analyses for the recovery of bighorn sheep in the Peninsular Ranges

Creator:: Ostermann, Stacey D.
Abstract:: The status of wild sheep in North America typifies the plight of many wildlife species in modern times: wild sheep have declined to 10-40% of their numbers during pristine times and on a global scale approximately 31% of Caprine are considered threatened or critical. As human populations and the number...

Sulfobromophthalein disposition in rainbow trout (Salmo gairdneri) as influenced by carbon tetrachloride intoxication

Creator:: Gingerich, William H.
Abstract:: Clinical methods to diagnose specific organ dysfunction have not been evaluated in fishes. To determine if an accepted clinical test of mammalian liver function could be applied to fishes, the hepatic disposition of the organic anion sulfobromophthalein (BSP) was studied in rainbow trout (Salmo gairdneri) treated with a model hepatotoxicant....

Abstract:: Nine isolates of bacteria recovered from fish dying at marine facilities were collected from different geographic areas. The strains included: an isolate from chinook salmon (Oncorhynchus tshawytscha) reared in net pens in New Zealand, an isolate from chum salmon (Oncorhynchus keta) held at a laboratory in Oregon, USA., and seven...

Impacts of agricultural drainwater and contaminants on wetlands at Kesterson Reservoir, California

Creator:: Schuler, Carol Ann, 1946-
Abstract:: Kesterson Reservoir (Kesterson) received subsurface agricultural drainwater containing high levels of salts and other minerals from farmland in the San Joaquin Valley of California. Aquatic plants and invertebrates were sampled at Kesterson in May, August, and December of 1984. The reservoir supported a different biota and lower species diversity than...

Quantitative genetics of chum salmon, Oncorhynchus keta (Walbaum)

Creator:: Smoker, William Williams
Abstract:: Chum salmon from different stocks were bred together in two experiments. Three stocks contributed gametes to one experiment, two stocks to another. Sibling groups of eggs, alevins, and fry were maintained in a common environment. Variability of development rates, rearing performance, susceptibility to disease, and behavioral traits was partitioned into...

Cumulative effects of land use on salmon habitat in southwest Oregon coastal streams

Creator:: Frissell, Christopher Andrew, 1960-
Abstract:: As part of a hierarchical approach to classifying watersheds and stream habitats based on geomorphic and geologic criteria, we defined ten classes of fluvial and lacustrine habitats at the scale of valley segments. Valley segments are landscape units which encompass surface waters and the adjacent floodplains and hillslopes with which...

Classification and management of earthen aquaculture ponds, with emphasis on the role of the soil

Creator:: Bowman, James R.
Abstract:: Soil, water, and climatic classification systems are reviewed as background for the construction of a classification system for earthen aquaculture ponds. The physical and chemical properties of important soil types are also reviewed because of the critical role that the soil plays in earthen pond systems. A pond classification system...

Factors affecting the abundance of fall chinook salmon in the Columbia River

Creator:: Van Hyning, Jack M.
Abstract:: A study of the population ecology of Columbia River fall chinook salmon, Oncorhynchus tshawytscha (Walbaum), was made in an attempt to determine the cause of a serious decline in this run which occurred in the early 1950's. Fluctuations in abundance of major salmon runs the North Pacific were examined to...
