The microscope in the hatchery

Without the aid of the microscope, it is safe to assume that fish Culture would now stand exactly where it did seventy-five years ago when methods of artificial fertilization were first applied. It is also safe to assume that the results from fish culture would be as unsatisfactory as they were at that time when the fishery resources were steadily...

The bacterial diseases of fish

Of all the diseases responsible for the losses in the hatchery, those caused by the microscopic one-celled organisms, the bacteria, are the most common and present the most serious problem to the hatcheryman. They are found at practically every trout and salmon hatchery during some period of the year. The symptoms of the diseases they cause are...

The protozoan diseases of hatchery fish

Following the somewhat bleak picture painted in the consideration of the bacterial diseases of hatchery fish in the last number of The Progressive Fish Culturist, it is a relief to turn to another large group of fish diseases caused by small, single-celled parasitic animals known as the protozoa. To the hatcheryman, the protozoan diseases of fish...

The Bureau of Fisheries disease service

Picture yourself bending over a trough picking eggs. The clatter of hoofs suddenly rings from the snow-covered hatchery roof—or if you must be technical—from the driveway. The hatchery door opens and in walks a bewhiskered gentleman wearing a brilliant red suit—it's Santa Claus. He walks slowly over to where you are standing...

Ulcer disease of trout

During the summer of 1933, lesions of a disease were noted among some fingerling brook, rainbow, blackspotted, and lake trout at the Cortland (New York) trout hatchery. Although these lesions bore a marked superficial resemblance to those of furunculosis, they were sufficiently atypical to warrant further investigation. A more detailed examination...

A fungus disease in fishes of the Gulf of Maine

1. A fungus disease of epidemic proportions was found in the common sea herring (Clupea harengus) throughout the Gulf of Maine. 2. The fungus was also found to infect the common winter flounder (Pseudopleuronectes americanus) and the alewife (Pomobolus pseudoharengus). 3. The causative agent was found to be a species of fungus belonging to the...

The chemical disinfection of trout ponds

The need for knowledge concerning the prevention and control of fish diseases has never been greater than it is in this present era of economy when two fish must be raised in the same water which once supported but one. Fish pathologists have contributed a great deal to our knowledge of fish diseases, but there is still much to be learned,...
