Grass Carp are invasive fish moving toward Wisconsin waters from the Illinois River and the Mississippi River. They are also intentionally and illegally stocked into private ponds. The term “Asian Carp” is sometimes used to describe this invasive species, along with the bighead, black and silver carp. Grass Carp have elongate, torpedo-shaped bodies without barbels. Body color is dark olive, shading to brownish-yellow on the sides, with a white belly and large, slightly outlined scales.
