Fish Species, Some Uncommon, Collected From The Lower Minnesota River, Daniel B. Wilcox, Bruce D. Lorenz, Vincent Kranz

Journal of the Minnesota Academy of Science

Fish collections were made in the lower Minnesota River in the vicinity of the Black Dog Generating Plant and at the intake structure of the plant from April, 1976, to April, 1977 as part of a section 316(b) demonstration study. Composition of the fish community of the area is reported along with notes on several species whose occurrence was considered unusual . New information on the occurrence of river carpsucker (Carpiodes carpio Rafinesque) and river darter (Percina shumardi, Girard) to the Minnesota River is also presented.

Occurrence Of Corbicula Manilensis Phillipi In The Lower Minnesota River, Steven E. Cummings, James A. Jones

Journal of the Minnesota Academy of Science

On March 2, 1978, several empty shells of the fresh water clam, Corbicula manilensis Phillipi, were collected in the Minnesota River near the Blackdog electric generating plant in Burnsville, Minnesota. Since this Asiatic species was first observed in America in 1935, it has spread into all major river systems of North America. Its northernly extension in the Mississippi River system was, however, thought to end in northeast Iowa and to exclude Minnesota. Occurrence of this species is a potential liability because it often exerts a disruptive influence in the community that it invades.
