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 ...

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.

How High Can Brook Trout Jump? A Laboratory Evaluation of Brook Trout Jumping Performance

Transactions of the American Fisheries Society, 2006
AbstractQuantitative data on how high brook trout Salvelinus fontinalis can jump are crucial for efforts by fisheries managers to exclude brook trout from streams containing native cutthroat trout Oncorhynchus clarkii subspp. and to build effective fishways for brook trout migration.

Learning ability of triploid brook trout

Journal of Fish Biology, 1995
Triploid brook trout (Salvelinus fontinalis) did not differ from diploids in their initial directional preference within a Y‐maze, electrical shock response threshold, or learning ability.

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.

Brook trout spawning areas in lakes

Ecology of Freshwater Fish, 1998
Abstract—Nine lakes containing self‐sustaining populations of brook trout (Salvelinus fontinalis) were surveyed to provide quantitative information on the abundance and distribution of redd sites. We measured rates of groundwater flow at redds in four of these lakes, and in one of these lakes we also compared the frequency of site use over four years ...

Gastric Evacuation Rates of Brook Trout

Transactions of the American Fisheries Society, 2004
Abstract We estimated the gastric evacuation rate (GER) of brook trout Salvelinus fontinalis at five different temperatures (4.3, 9.1, 12.1, 15.6, and 17.0°C). Fish were fed a mixed meal of fly larvae and beetle larvae, and stomach contents were sampled by gastric lavage at various times over a 48–72-h period to determine the proportional dry weight of

Relationship Between Wetlands and Mercury in Brook Trout

Archives of Environmental Contamination and Toxicology, 2006
The purpose of this study was to determine if wetlands influence mercury concentrations in brook trout (Salvelinus fontinalis), benthic macroinvertebrates, and stream water. On September 26, 2005, water samples, benthic macroinvertebrates, and brook trout were collected from four streams in western Maryland under low-flow conditions. Water samples were
