Creator:: Caldwell, Richard S., Oregon State University. Agricultural Experiment Station, and Oregon State University. Department of Fisheries and Wildlife
Abstract:: This report summarizes a study which sought to provide toxicity data for pulp mills near Coos Bay through a series of toxicity bioassays. The study also surveyed benthic and beach fauna to identify macro-organisms so individual assessments of water quality requirements could be made.

The reproductive biology of the mountain cottontail rabbit in Oregon

Creator:: Powers, Roger Alan
Abstract:: The reproductive characteristics of the mountain cottontail rabbit, Sylvilagus nuttalli (Bachman), were investigated from 269 specimens collected in central Oregon between 28 May 1968 and 28 August 1969. Male rabbits were in breeding condition between mid-February and 3 July 1969. Nearly 77% of the females bore four litters between 7...

Abstract:: The experiment was conducted at the Soap Creek farm ponds near Corvallis, Oregon. Oregon Moist Pellet and Purina Trout Chow at three different rates of feeding for each diet were used to feed fingerling channel catfish stocked at the rate of 1,000 per acre. A complete random design and Fisher's...

Morphological and meristic characteristics of ten populations of blackside dace, Rhinichthys osculus nubilus (Girard ), from western Oregon

Creator:: Zirges, Malcolm H.
Abstract:: Blackside dace, Rhinichthys osculus nubilus (GIRARD), were collected from ten western Oregon streams and examined for variation among morphological and meristic characters. Several characters were observed to vary between populations studied. Number of vertebrae, number of scales in and above the lateral line, length of snout, and depth of body...

Plumage development and growth of young whooping cranes

Creator:: Stephenson, James Dale
Abstract:: Plumage development and growth were studied in young whooping cranes (Grus americana) from hatching until 450 days of age. The downy stage of the young cranes lasted about six weeks; the development of the juvenal plumage took until 100 days of age, and the molt to the adult or all...

The influence of diet and dieldrin on the growth and body composition of underyearling rainbow trout

Creator:: Phillips, Glenn R.
Abstract:: The effects of a sublethal concentration of dieldrin (0. 2 ppb) in the water on the growth and body composition of underyearling rainbow and cutthroat trout held in aquaria and fed different rations of tubificid worms or Oregon moist pellets were studied at Oak Creek Fisheries Research Laboratory, Oregon State...

Some effects of dissolved oxygen concentration on feeding, growth and bioenergetics of juvenile Coho salmon

Creator:: Thatcher, T. O.
Abstract:: The effects of three levels of dissolved oxygen (8, 5 and 3 mg/l) upon the feeding, growth and bioenergetics of juvenile coho salmon, Oncorhynchus kisutch (Walbaum), were determined in laboratory studies. Experiments with individual fish were conducted during the summer, fall and spring to measure rates of food consumption, standard...

Crop-milk cycles in band-tailed pigeons and losses of squabs due to hunting pigeons in September

Creator:: Zeigler, Don L.
Abstract:: The production of crop-milk in band-tailed pigeons was investigated to estimate losses of squabs that occur from hunting pigeons during September.¹ Living birds held captive were examined with a cystos cope and pigeons killed by hunters were examined in the field to determine changes in gross appearance of crops and...

Effects of dieldrin on the intrinsic rate of increase of the guppy, Poecilia reticulata Peters

Creator:: Roelofs, Terry Dean
Resource Type:: Dissertation

An evaluation in rainbow trout of biliary excretion of sulfobromophthalein and effects of biliary excretion on the toxicity of rotenone

Creator:: Schmidt, Dana C.
Abstract:: Biliary excretion has been of considerable interest in mammals but has not been extensively studied in fish. To understand the significance of biliary excretion in rainbow trout (Salmo gairdneri), two studies were conducted. The objective of the initial study was to evaluate the ability of rainbow trout to excrete a...

Black bear population ecology

Creator:: Lindzey, Frederick Grier
Abstract:: Despite relatively mild weather, black bears (Ursus americanus) in southwestern Washington entered dens and remained for an average of 126 days. Bears entered their dens during a 5-week period which began on 21 October. A significant difference (P < 0.05) was found among the average dates of den entrance of...

The effects of sewage on the distribution and abundance of benthic animals in a Puget Sound bay

Creator:: Shapeero, William L.
Abstract:: The effects of discharged sewage on physico-chemical conditions and the distribution and abundance of marine benthic animals were studied in Shilshole Bay, a part of Puget Sound, off Seattle, Washington. For over 50 years prior to 1965, when this study was initiated, 87,300 pounds (32,400 pounds BOD) per day of...

A genetic study of the red-band trout (Salmo sp.)

Creator:: Wilmot, Richard L.
Abstract:: A group of trout that reside in streams of the desiccating lake basins of southeastern Oregon differ markedly from other known Salmo. Known commonly as the red-band trout, this fish was subjected to chromosome analysis for comparison with other species of western North American Salmo. The karyotype of the red-banded...

Aspects of comparative neuromuscular physiology and pharmacology of black bass (Micropterus salmoides) as evidenced by the action of diisopropylfluorophosphate

Creator:: Schneider, Phillip William
Abstract:: Neuromuscular physiology has been extensively investigated in several groups of vertebrates excluding fish. To understand the nature of neuromuscular transmission in this group, the response of the pectoral fin abductor muscle of black bass (Micropterus salmoides) to nerve stimulation under the influence of an anticho1inesterase agent was studied. Diisopropylfluorophosphate (DFP),...

Prediction of abundance of harvestable Dungeness crab (Cancer magister)

Creator:: Stefferud, Jerome Arthur
Abstract:: A method for predicting the harvest of commercial Dungeness crab (Cancer magister) one year in advance of the fishing season is described. The technique is based on the hypothesis that the relative abundance of sub-legal crabs one year is directly proportional to the harvest of legal crabs the following year....

Analysis of age determination methods for yellowtail rockfish, canary rockfish, and black rockfish off Oregon

Creator:: Six, Lawrence D.
Abstract:: Methods and utility of age determination of yellowtail rockfish (Sebastes flavidus), canary rockfish (Sebastes pinniger), and black rockfish (Sebastes melanops) collected off Oregon during 1972 to 1975 are discussed. Structures compared on the basis of the reproducibility of counts of annuli (consistency of readings) were the anal fin pterygiophore, opercle,...

Evaluation of baits and baiting techniques for Belding's ground squirrels

Creator:: Sullins, George Lamont
Abstract:: Quantitative data concerning bait preference and bait application were collected for Belding's ground squirrels (Spermophilus beldingi) during February-July 1975. Bait materials tested for preference were crimped oats, oatgroats, whole wheat, barley, rolled wheat, rye, chopped lettuce, chopped apple, oatgroats + Rhodamine B dye, oatgroats + starch paste, oatgroats + Rhoplex...
