The channel catfish, known informally as the "channel cat", is a species of catfish native to North America. They are North America's most abundant catfish species, and the official state fish of Kansas, Missouri, Nebraska and Tennessee. The channel catfish is the most fished species of catfish in the United States, with around 8 million anglers angling them per year. The popularity of channel catfish for food has contributed to the rapid expansion of this species' aquaculture in the United States. It has also been widely introduced to Europe, Asia and South America, and many countries consider it an invasive species.
