Wikipedia Abstract

The brown bullhead (Ameiurus nebulosus) is a fish of the Ictaluridae family that is widely distributed in North America. It is a species of bullhead catfish and is similar to the black bullhead (Ameiurus melas) and yellow bullhead (Ameiurus natalis). It was originally described as Pimelodus nebulosus by Charles Alexandre Lesueur in 1819, and is also referred to as Ictalurus nebulosus. The brown bullhead is also widely known as the "mud pout," "horned pout," "hornpout," or simply "mud cat," along with the other bullhead species.

Invasive Species

Ameiurus nebulosus, the brown bullhead, is a species of catfish native to North America and introduced to a number of other countries around the world as a game fish. It is a hardy species that can tolerate a wide range of environmental conditions, including water pollution, allowing it to successfully establish outside of its native range. Some concern has been raised over its invasive potential, but there is a lack of information on its effects.
