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...

Channel catfish virus experiments with different strains of channel catfish
J.A. Plumb, O.L. Green, R.O. Smitherman, G.B. Pardue
1975, Transactions of the American Fisheries Society (104) 140-143
Experimental infections of channel catfish virus were made by feeding virus to six strains of 1‐, 2‐, and 3‐month‐old channel catfish from different geographical areas and two hybrid strains. There was no significant difference in mortality between age groups. Mortality rates differed significantly between the various strains, with mean mortality...

The U.S. Soil Conservation Service is actively engaged in the implementation of flood- and soil-erosion reducing measures in Texas under the authority of "The Flood Control Act of 1936 and 1944" and "Watershed Protection and Flood Prevention Act" (Public Law 566), as amended. The Soil Conservation Service has found that...

A disease of freshwater fishes caused by Tetrahymena corlissi Thompson, 1955, and a key for identification of holotrich ciliates of freshwater fishes
G. L. Hoffman, M. Landolt, J.E. Camper, D.W. Coats, J.L. Stookey, J.D. Burek
1975, Journal of Parasitology (61) 217-223
Tetrahymena corlissi, a free-living protozoan, apparently caused the death of large numbers of guppies (Poecilia reticulatus) and occasionally other fishes, in aquaria and hatcheries at several locations. Apparently the disease occurs when the fish and protozoan populations are both at a high level of density. The signs include white spots...
Thin-section electron microscopy of mature Myxosoma cerebralis (Myxosporidea) spores
P.D. Lunger, B.L. Rhoads, K. Wolf, M.E. Markiw
1975, Journal of Parasitology (61) 476-480
The morphology of purified, mature Myxosoma cerebralis spores was examined by thin-section electron microscopy. Surface architecture corresponded closely to that described in an earlier scanning electron microscopy study of this organism (Lom and Hoffman, 1971). A uniformly thick spore wall is composed of finely granular, electron-lucent material. Intrawall "valvoplasm" at...

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...
Calculated geochronology and stress field orientations along the Hawaiian chain

1975, Earth and Planetary Science Letters (26) 145-155
A new method has been discovered for calculating ages of the main shield building stages of volcanoes along the Hawaiian chain from Kilauea to the Hawaiian-Emperor bend. The method is based on a graphical technique for hypothetical subtraction of distance intervals that...
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...
Mercury distribution in ancient and modern sediment of northeastern Bering Sea

1975, Marine Geology (18) 91-104
Reconnaissance sampling of surface and subsurface sediment to a maximum depth of 80 m below the sea floor shows that typical values of 0.03 p.p.m. and anomalies of 0.2-1.3 p.p.m. mercury have been present in northeastern Bering Sea since Early Pliocene time. Values are highest in modern beach (maximum 1.3...

Phallodrilus hallae, a new tubificid oligochaete from the St. Lawrence Great Lakes
David G. Cook, Jarl K. Hiltunen
1975, Canadian Journal of Zoology (53) 934-941
The predominantly marine tubificid genus Phallodrilus is defined, a key to its nine species constructed, and an illustrated description of Phallodrilus hallae n. sp. from the St. Lawrence Great Lakes presented. The species is distinguished from other members of the genus by its well-developed atrial musculature, extensions of which ensheath the posterior prostatic ducts.Phallodrilus...
