Interrenal and metabolic responses to stress and their modifying factors in juvenile salmonid fishes

Creator:: Barton, Bruce Alexander
Abstract:: Genetic, ontogenetic, and environmental factors modified characteristic interrenal and glycemic responses to stress in juvenile salmonid fishes. During continuous confinement stress, plasma cortisol rose more quickly in chinook salmon, Oncorhynchus tshawytscha, acclimated to high rather than medium or low temperatures; hyperglycemia following either acute or chronic stress was also highest...

Fertilization of salmonid eggs with cryopreserved sperm

Creator:: Ott, Alvin G.
Abstract:: Numerous fishery researchers have attempted to preserve viable fish sperm, but only three investigations were successful in the fertilization of fresh eggs with frozen and thawed sperm: Blaxter (1953); Hoyle and Idler (1968); and Graybill and Horton (1969). Significant advances reported in this thesis were: the development of suitable life...

Phylogeny and zoogeography of glyptocephalines (Pisces: Pleuronectidae)

Creator:: Chiu, Tai-sheng
Abstract:: Hypotheses of phylogenetic and historical zoogeographic relationships of glyptocephalines (Glyptocephalus cynoglossus, G. zachirus, G. stelleri, Microstomus kitt, H. pacificus, H. achne, Embassichthys bathybius, and Tanakius kitaharae) were constructed based on comparative anatomy and external morphology. The phylogenetic approach was cladistic and character polarity was determined by using out-group comparison. One...

Mechanisms affecting the bioaccumulation of dietary quinoline by rainbow trout (Salmo gairdneri)

Creator:: Dauble, Dennis D.
Abstract:: Factors that influenced the uptake, storage, and elimination of dietary quinoline by rainbow trout (Salmo gairdneri) were studied to obtain an understanding of the mechanisms affecting the bioaccumulation of dietary contaminants in teleosts. Rainbow trout readily absorbed ¹⁴C-quinoline from pelleted food (1% ration at 138 ug quinoline/g food) and most...

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...

Biochemical and serological comparison of selected Vibrio spp. isolated from fish

Creator:: Pipoppinyo, Somsak
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...

The migratory pattern of audlt sockeye salmon (Oncorhynchus nerka) in Bristol Bay as related to the distribution of their home-river waters

Creator:: Straty, Richard R.
Abstract:: The individual stocks of sockeye salmon that make up the annual spawning migration to the Bristol Bay region of Western Alaska are produced in the lakes and streams of ten major river systems, which discharge into the bay over a shoreline distance of 120 miles. The hypothesis adopted in this...

Direct and indirect effects of livestock grazing intensity on processes regulating grassland bird populations

Creator:: Johnson, Tracey N.
Abstract:: In grasslands, grazing by large ungulates can influence vegetation structure, composition, primary productivity, and ultimately, ecosystem functioning. While grazing represents a complex disturbance, grazing intensity largely determines the effects of grazing on vegetation. Structural and compositional changes in the plant community caused by grazing could have bottom-up effects on species...

Impact of land use patterns and agricultural practices on water quality in the Calapooia River Basin of western Oregon

Creator:: Mueller-Warrant, G. W., Griffith, S. M., Whittaker, G. W., Banowetz, G. M., Pfender, W. F., Garcia, T. S., and Giannico, G. R.
Abstract:: Agricultural practices, including tillage, fertilization, and residue management, can affect surface runoff, soil erosion, and nutrient cycling. These processes, in turn, may adversely affect (1) quality of aquatic resources as habitat for amphibians, fish, and invertebrates, (2) costs of treating surface and ground water to meet drinking water standards, and...

The relationship between the gut and the water-electrolyte balance of a marine teleost, Enophrys bison (Girard)

Creator:: Sleet, Randolph Bullock
Abstract:: In higher vertebrates, normal digestion and absorption by the gastrointestinal tract are dependent on the orderly and controlled transit of intraluminal contents. A relationship between fluid passage through the gut and absorption from the gut has yet to be examined in fish. In marine teleosts, the osmolality and ion concentration...
