The black bullhead is found naturally from southern Ontario to the Gulf of Mexico between the Appalachian mounts to Montana, and has been introduced in Arizona, California and other western states in the USA, as well as a few east of the Appalachians. Although the three species of bullheads are named by color, they all can vary throughout all the colors. You need a scientific definition to tell them apart but they are all excellent when fried! The record black bullhead weighed an even 8 pounds (3.62 kg) and was caught in New York, USA on August 1, 1951.

I think illinois record is 5 pounds or something. not bad for a native smaller cat TYPE fish.
