Upper Missouri River Basin Aquatic GAP Fish Distribution Model Accuracy Assessment and White Sucker, Catostomus commersonii, Population Characteristics in the Upper Missouri River Basin
Fish species surveys were done at 61 sites in 6 drainages throughout the upper Missouri River Basin. A total of 21,204 fish were collected, representing 42 species and 11 families. Minnows (family Cyprinidae) dominated the catch (77.9%), followed by suckers (family Catostomidae, 6.5%), and catfishes...
