Bacterial diseases of fishes: Diagnostic procedures for gram-negative pathogens
E. B. Shotts Jr., G. L. Bullock
1975, Journal of the Fisheries Research Board of Canada (32) 1243-1247
A diagnostic scheme employing 10 media, 4 reagents, and 5 specific antiserums has been devised for identification of gram-negative pathogens of fishes. The scheme is not intended for detailed speciation of organisms, but for generic identification of organisms associated with infected fishes. Diagnosis can be accomplished in 24 h with selective...

Amino acid supplementation of casein in diets of Atlantic salmon (Salmo salar) fry and of soybean meal for rainbow trout (Salmo gairdneri) fingerlings
G. L. Rumsey, H. G. Ketola
1975, Journal of the Fisheries Research Board of Canada (32) 422-426
Fry of Atlantic salmon (Salmo salar) fed a diet containing isolated fish protein grew significantly faster than those fed a diet containing casein without supplemental amino acids, and had improved feed conversion and lower mortality. Supplementing the casein diet with essential amino acids to the levels in the isolated fish...

Fluorescent antibody identification and detection of the Corynebacterium causing kidney disease of salmonids
G. L. Bullock, H. M. Stuckey
1975, Journal of the Fisheries Research Board of Canada (32) 2224-2227
An indirect fluorescent antibody technique (FAT) has been developed for serological identification, diagnosis of kidney disease (KD), and detection of subclinical infections of KD. Rabbit or goat antikidney disease serum and appropriately labeled immunoglobulin was found to be specific for the KD bacterium. The technique was superior to examination of...

Effects of pH on toxicity of antimycin to fish
L. L. Marking
1975, Journal of the Fisheries Research Board of Canada (32) 769-773
Detoxification of antimycin at pH 9.5 was caused by two factors. The piscicide was biologically unavailable at the high pH, and this unavailability was reversed by decreasing the pH of water solutions. Simultaneously antimycin detoxified with time, and the resulting loss in toxicity was irreversible. The toxicity of antimycin was...
The role of indigenous wild, semidomestic, and exotic birds in the epizootiology of velogenic viscerotropic Newcastle disease in southern California, 1972-1973
G.L. Pearson, M.K. McCann
1975, Journal of the American Veterinary Medical Association (167) 610-614
During an epornitic of velogenic viscerotropic Newcastle disease (VVND) in southern California, free-flying wild birds, captive and free-ranging semidomestic birds, and exotic birds were collected from the quarantine area to determine their role in the epizootiology of the disease. The VVND virus was isolated from 0.04% of 9,446 free-flying wild...
Residue dynamics of quinaldine and TFM in rainbow trout
J. B. Hunn, J. L. Allen
1975, General Pharmacology (6) 15-18
Study of the residue dynamics of 2-methylquinoline (quinaldine) and 3-trifluoromethyl-4-nitrophenol (TFM) in rainbow trout yielded the following findings:1. Uptake and distribution of TFM by trout was influenced by the biotransformation of the lipidsoluble free phenol. No such effect was observed with quinaldine.2. Disappearance of quinaldine and TFM from gallbladder bile...
Use of elevated nest baskets by ducks
Harold A. Doty, F.B. Lee, A.D. Kruse
1975, Wildlife Society Bulletin (3) 68-73
Open-top nest baskets were mounted on upright metal poles in various wetlands to assess the value of baskets as a potential technique for increasing duck nest success. Observations were made from 1966-1968 in North and South Dakota, Minnesota, and Wisconsin and were continued through 1973 in North Dakota. Baskets were...

Variation in response of channel catfish to Henneguya sp. infections (Protozoa: Myxosporidea)
J. P. McCraren, M.L. Landolt, G. L. Hoffman, F. P. Meyer
1975, Journal of Wildlife Diseases (11) 2-7
Infections in channel catfish (Ictalurus punctatus, Rafinesque) induced by the sporozoan Henneguya (Protozoa: Myxosporidea) result in seven known and diverse disease manifestations. Most outstanding is an interlamellar branchial form responsible for significant losses among immature catfish, and a unique papillomatous form. The question of whether or not the species of Henneguya involved in these...

Vertical crustal movements preceding and accompanying the San Fernando earthquake of February 9, 1971: A summary
Robert O. Castle, Jack P. Church, Michael R. Elliot, Nancy L. Morrison
1975, Tectonophysics (29) 127-140
Comparative elevations referred chiefly to a tidal bench mark with a history of relatively positive movement show that much of the Transverse Ranges of southern California sustained major changes in elevation both before and in association with the ML 6.4 San Fernando earthquake of February 9, 1971. Preseismic changes in...
Trace element evaluation of a suite of rocks from Reunion Island, Indian Ocean
R. A. Zielinski
1975, Geochimica et Cosmochimica Acta (39) 713-734
Reunion Island consists of an olivine-basalt shield capped by a series of flows and intrusives ranging from hawaiite through trachyte. Eleven rocks representing the total compositional sequence have been analyzed for U, Th and REE. Eight of the rocks (group 1) have positive-slope, parallel, chondrite-normalized REE fractionation patterns. Using a...
Uranium determination in natural water by the fissiontrack technique
G.M. Reimer
1975, Journal of Geochemical Exploration (4) 425-431
The fission track technique, utilizing the neutron-induced fission of uranium-235, provides a versatile analytical method for the routine analysis of uranium in liquid samples of natural water. A detector is immersed in the sample and both are irradiated. The fission track density observed...
New dimensions in diseases affecting waterfowl
Milton Friend
1975, Conference Paper, Proceedings of the first international waterfowl symposium
We start off with light heart, but as we near the marsh, we stop abruptly in shock and horror. The shoreline, where only last evening we saw thousands of sleek, apparently healthy birds, is now littered with their bodies. Most of them are ducks, but here and there we see...
Marine terraces; datum planes for study of structural deformation
N.K. Huber
1975, Earthquake Information Bulletin (USGS) (7) 3-7
Along the earthquake-prone coastal area of north-central California, geologists are searching for criteria to establish the nature, extent, and rate of crustal movement or deformation that may be related to activity along known or postulated faults. This search has led to a study of marine terraces along the coast between...

S.J. Proctor, G.L. Pearson, Louis Leibovitz
1975, Wildlife Disease Conference (67) 1-16
The first major epizootic of duck plague in free-flying waterfowl occurred at Lake Andes, South Dakota, in January and February, 1973. Duck plague was diagnosed in black ducks, mallards, pintail-mallard hybrids, redheads, common mergansers, common golden eyes, canvasbacks, American widgeon, wood ducks, and Canada geese, indicating the general susceptibility of...

History of fish toxicants in the United States
K.B. Cumming
1975, Special Publication 4
Many bodies of water have been overrun with fish species that are undesirable for the well-being of endemic aquatic biota and are of little or no interest to anglers. This situation has resulted from the transplanting of fish, creation of new waters, increasing fishing pressure and changing water quality. Although...
Preliminary description and interpretation of cores and radiographs from Clear Lake, Lake County, California: Core 7
John D. Sims, Michael J. Rymer
1975, Open-File Report 75-144
Clear Lake, California is located in the California Coast Ranges about 120 km north of San Francisco and is the largest freshwater lake wholly within California. The lake basin is tectonically controlled (Anderson, 1936; Brice, 1953, Sims and Rymer, 1974) and the area seismically active (Coffman and von Hake, 1973).Interest...
