An Evaluation of the Occurrence of Micronuclei and other Nuclear Abnormalities in Fishes from the Great Lakes Basin, United States
… occurrence rates among species. Brown bullhead (Ameiurus nebulosus ) expressed MN at a lower rate when compared to either largemouth bass (Micropterus salmoides) or smallmouth bass ( Micropterus dolomieu). White sucker (Catostomus commersoni ) express MN at a lower rate when compared to …

Nutritional condition and stress response of fishes along a gradient of habitat quality in the St. Lawrence River: physiological consequences of anthropogenic habitat degradation
… bass Micropterus salmoides, brown bullhead Ameiurus nebulosus, and logperch Percina caprodes had altered GC function as a result of anthropogenic stream degradation, whereas white sucker Catostomus commersonii and pumpkinseed Lepomis gibbosus did not. Together, my results show that different …

The Status and Distribution of the Topeka Shiner Notropis topeka in Eastern South Dakota
… tadpole madtoms Noturns gyrinus, black bullheads Ameiurus melas, and bigmouth shiners Notropis dorsalis. Habitat preferences were based on three stepwise logistic regression models: physical habitat water quality, and substrate composition at the reach scale. The physical habitat model indicated …

Population Characteristics and Sampling Methods of Catfish for the James and Big Sioux Rivers
… on trotlines baited with live black bullheads Ameiurus melas, especially if set along river bends with depths > l m and with complex woody debris. Sea-circle hooks caught 70 catfish compared to 136 catfish that were caught on O'Shaughnessy style hooks and 122 catfish caught on modified circle …

Determination of genotoxic stress in feral populations of bullheads and carp using the alkaline single cell gel assay.
… in this study were benthic feeding bullheads (Ameiurus nebulosus) and carp (Cyprinus carpio). In preliminary studies, on electrophoresis of erythrocyte DNA under alkaline conditions I found a linear increase in the DNA length:width ratio over a broad range of cyclophosphamide (a clastogen) …

Food Habits of Walleye and Saugeye When Stocked as Secondary Predators into Small South Dakota Impoundments
… saugeye fed extensively on black bullheads Ameiurus me/as while walleye did not. A winter gill-net sample was conducted on Lake Tunkisula in February 1999. Walleye were found to feed exclusively on invertebrates during winter while saugeye incorporated fishes in their diet. Regardless of …
