Lymphosarcoma in a Brook Trout

Journal of Wildlife Diseases, 1997
A 2-yr-old female brook trout, Salvelinus fontinalis, maintained at a state fish hatchery in New York (USA) was culled from the breeding stock. At necropsy, it had a markedly enlarged kidney. On histopathological examination, lymphoblastic lymphoma was diagnosed in several organs including kidney, dorsal musculature, intestines, liver, gill ...

OVARIECTOMY IN A BROOK TROUT (SALVELINUS FONTINALIS)

Journal of Zoo and Wildlife Medicine, 2002
A 1.7-kg mature, female brook trout (Salvelinus fontinalis) was diagnosed with egg retention. Eggs could not be manually stripped and so were surgically removed. To prevent future complications, bilateral ovariectomy was performed. Complications were minimal, and the fish resumed eating within 2 days.

Sulfonamide Toxicity in Brook Trout

Transactions of the American Fisheries Society, 1955
Abstract Sterility was observed in female brook trout that were treated with sulfamerazine at frequent intervals for 2 years to control endemic furunculosis. Feeding sulfamerazine for a period of 8 months caused massive kidney damage similar to that observed in humans who develop allergies to “sulfa” drugs.

Acid Deposition and Brook Trout

2023
New Hampshire is being negatively affected by acid deposition. The average pH of waters in New Hampshire are very acidic, which causes issues with the environment of brook trout. This is an issue that is mainly caused by the geographic make up of New Hampshire that hasn’t been addressed in this state by ecologists. In order to address this problem,

Responses of pineal photoreceptors in the brook and rainbow trout

Cell and Tissue Research, 1980
Electron microscopy of the pineal receptor cells in light- and dark-adapted brook trout, Salvelinus fontinalis and the rainbow trout, Salmo gairdneri, revealed no significant differences in the tubular and filamentous elements of the inner segment, neck and supranuclear regions. However, changes in synaptic relations between the photoreceptor and nerve

Biological effects of fenitrothion in the diet of brook trout

Bulletin of Environmental Contamination and Toxicology, 1973
The possibility that aquatic and terrestrial insects, killed by operational spray doses of fenitrothion, may cause lethal or sublethal effects directly in salmonids, has been shown by these experiments to be unlikely. The highest level found in poisoned insects by Penney (personal communication) is 3,000 times less than the level at which behavioural ...
