15 Fin-tastic Facts About The Smoky Madtom For Kids

Smoky Madtom Fact File

The smoky madtom is a species of the catfish group endemic to North America, specifically Tennessee in the USA. In Tennessee, the species used to be native to the Abrams Creek but was accidentally extirpated when an ichthyocide was introduced to enhance trout fishing. During the 1980s the Citico Creek was found to have the smoky madtom fish too, which were then reintroduced to Abrams Creek again. The average life expectancy for this rare catfish species is only four years, meaning it can breed and spawn only twice in its lifetime. This is a very low rate of reproduction. It is a mostly olive-brown fish with white to yellow undersides. It is small, only about 2 in (5 cm) long and feeds on aquatic insects and invertebrates during the night. The species itself get preyed upon by the smallmouth bass. The smoky madtom, as of today is considered to be a Vulnerable species (not an endangered species) by the IUCN, but its populations in the Abrams Creek as well as the Citico Creek are believed to be stable.
