"We had very little success spawning madtoms in captivity, but we were successful in hatching and raising young from fertilized eggs collected from the wild." And they were successful!
Siltation, a major threat to bottom dwelling fishes like madtoms, will have to be addressed by partnering with local landowners (many of whom are the parents of the same students that helped in the release) to implement best management practices to help maintain good water quality.
Freckled madtoms are found in medium-sized creeks to large rivers.
The natural history of madtoms (genus Noturus), North America's diminutive catfishes.
In 1996, researchers at Emporia State University in Kansas successfully spawned Neosho madtoms (Wildhaber 2006).
The Neosho madtom (Noturus placidus) is a small catfish endemic to the mainstems of the Neosho and Cottonwood rivers in Kansas and Oklahoma and the Spring River in Kansas, Oklahoma, and Missouri.
Smaller members of the catfish clan--stonecats, madtoms
, and bullheads--make excellent baits.
The slabrocks were also being used by several other darter species, as well as madtoms
. As a result of this success, additional spawning substrate will be placed at suitable locations in the Elk River in the near future.
Insufficient numbers of yellowfin and smoky madtoms existed in the wild to supply individuals for direct reintroductions, so nests containing eggs and fry were taken in the spring of 1986 from another Little Tennessee River tributary, Citico Creek in the Cherokee National Forest, Tennessee, for captive rearing.
Although captive spawning technology for the madtoms still eludes us, approximately 1,500 smoky and 500 yellowfin madtom young that were reared from eggs and fry collected in Citico Creek have been released into Abrams Creek.

An example of how SIFT participants are working together under the strategy involved the pygmy madtom
(Noturus stanauli) release in May 2001.
