Open encyclopedia reference
The mountain madtom (Noturus eleutherus) is a North American species of temperate freshwater fish belonging to the Noturus genus of the family Ictaluridae. The species was first described to the United States National Museum by Professors Jordan and Gilbert in the Big Pigeon River. The mountain madtom has a body that is characterized as being robust, and by the toxic sting that is associated with their pectoral and dorsal spines. Currently, the Pigeon River Recovery Project is working to try to restore the mountain madtom population that was lost in fisheries. Aside from the Pigeon River Recovery Project, there is little management being applied to this species, and it is currently listed on the threatened species list for the state of Tennessee.
