Fish mycobacteriosis (Tuberculosis)
The etiologic agent for the bacterial disease, "fish tuberculosis" (more correctly "mycobacteriosis"), was first observed in carp in 189& from a pond in France. Subsequently similar agents have been isolated from or observed in fish in fresh water, salt water, and brackish water, in fish in aquaria, hatcheries, and natural habitat~ (wild populations of fish). The disease has been recognized as an

Life history of the sea lamprey of Cayugaf Lake, New York
A life history study of the sea lamprey, Petromyson marinus Linnaeus, in Cayuga Lake, N.Y., was conducted during 1950, 1951, and 1952. One of the major objectives was to obtain biological data concerning this endemic stock of sea lampreys for comparison with the newly established stocks in the Great Lakes. Sexually mature sea lampreys captured on their spawning migration in Cayuga Inlet were the b

The reclamation of Indian and Abrams creeks in Great Smoky Mountains National Park
A complete program of stream reclamation was developed and applied on Indian and Abrams creeks in Great Smoky Mountains National Park. A salt-resistivity technique was used to estimate the dilution and velocity of a toxicant in running water. Streamside toxicity trials on resident fishes established minimal, effective concentrations of the rotenone material. The successful removals of undesirable

The electrical resistivity meter in fishery investigations
A portable resistivity (or conductivity) meter is easily used in fishery investigations to obtain rapid and precise measurements of the electrical resistance (or conductance) of waters. These measurements can be used to estimate the total dissolved solids content of waters, to facilitate the selection of appropriate gear for efficient electrofishing, and to determine the velocity, stretch-out, dil

Plasmoptysis and gelatin of erythrocytes in coagulation of blood of freshwater bony fishes
1. A clot-like material which results from very rapid plasmoptysis and hydrophyllic swelling of karyoplasm of erythrocytes from freshwater fish was reported. This attribute was found to a lesser degree in erythrocytes from an amphibian, but it was almost lacking in those of an aquatic reptile.2. Rapid clotting of fish blood with the usual clinical methods was confirmed in this work. Fish blood clo
