Bighead Carp are invasive fish moving toward Wisconsin waters from the Illinois River and the Mississippi River. The term “Asian Carp” is sometimes used to describe this invasive species, along with the silver, black and grass carp. Bighead Carp have low-set eyes and large upturned mouths without barbels. Their heads have no scales, and their body scales are very small. The Bighead Carp has dark blotches along the top of its body.
