347:. The captured fish were released into both Abrams Creek and Citico Creek irregularly to try to restore a population and save a population, respectively. The yellowfin madtom has had a 53% survival rate among its captured egg clutches, and new fish have been found in Abrams Creek almost every year since 1994. In 2003, though only 9 yellowfin madtom were found in Abrams Creek, they were believed to be wild-spawned, since tagged fish had not been released since 2001, marking what looks to have been a successful project in restoring them in Abrams Creek.

Both catfish are small and are present in the same river systems, with declining populations. The separation of the yellowfin madtom from its biggest competitor seems to have had negative effects on its populations, as they start to compete among themselves.

The yellowfin madtom has a relatively short lifespan. Generally, it lives up to four years and is most often found in the pools and streams in which they were born. Their breeding season begins in late May and continues through late July. The males are able to mate once during the breeding season and

Since 1986, populations of the yellowfin madtom from Citico Creek have been captured and bred in laboratory to be reintroduced into Abrams Creek in Blount County, Tennessee, which in 1957 had half of its 64 species extirpated by ichthyocides with the intention to increase trout fishery. From 1986

While no specific predator is known, the yellowfin madtom exhibits cryptic coloration and also hides itself in the daytime, both of which are predator-avoidance strategies. The yellowfin madtom is nocturnal animal and has been known not to try to escape captivity. Generally, it inhabits pools and

The yellowfin madtom is nocturnal and an opportunistic feeder. It preys on aquatic invertebrates, small fish, and detritus. During the daytime, the yellowfin madtom often hides in brushpiles or bedrock crevices and can even bury itself under several inches of gravel.
