Catfish in Miniature
gravel or rocks on the bottom. The current will sweep dislodged madtoms into your net. Because madtoms are small, the seine should have no larger than 1/4 inch mesh.
Three people can seine more efficiently by having two holding the seine while the "kicker" walks slowly downstream toward them.
You can also catch madtoms at night in riffles using a small-mesh dip net and a flashlight. Most youngsters love to try catching madtoms on overnight camping trips along Missouri's clear streams.
The Fishes of Missouri, by William L. Pflieger, contains information and classification facts concerning all the fish species found in our state. You can purchase or order this book through your regional conservation office or at a conservation nature center or online.
You are unlikely to come across the mountain madtom, Noturus eleutherus, or the Neosho madtom, Noturus placidus. Both have very limited distribution in Missouri. The mountain madtom has only been collected at four locations in Missouri, including 18 specimens collected from the Black River and St. Francis rivers.
The tadpole madtom, Noturus gyrinus, is the most abundant madtom in the lowland streams and ditches of southeast Missouri. It is also found in the creeks and backwaters of the Missouri and Mississippi rivers. The tadpole madtom is most often collected from quiet waters that have thick growths of submergent plants or accumulations of leaves, sticks and other organic debris.
The distribution of the freckled madtom, Noturus nocturnus, is similar to that of the tadpole madtom, but they are typically found in riffles or in portions of the stream that have gravel or rocky bottoms.
Noturus miurus, the brindled madtom, also inhabits many of the same lowland streams and ditches as the tadpole madtom, and is nearly as common. Brindled madtoms are more often found in pools, however. The species also inhabits the Spring River system in southwest Missouri.
In the western and northern Missouri Ozarks, the slender madtom, Noturus exilis, is the most common madtom in smalland medium-size streams that have gravel bottoms, clear water and permanent flow. This madtom is scarce in the southern Ozarks.
The stonecat, Noturus flavus, is the most common madtom in the large streams in the northern Ozarks and Prairie region. In the headwaters of these streams, it is often replaced by the slender madtom.
In the southern Ozarks of Missouri, the Ozark madtom, Noturus albater, is the most abundant madtom. It thrives in clear, steep streams with strong, permanent flow.
The checkered madtom, Noturus flavater, has a similar distribution to that of the Ozark madtom, except that it is absent from the St. Francis and Black rivers. In streams where it co-exists with Ozark madtoms, it is generally less abundant. Unlike the checkered madtom, it prefers backwaters and margins of quiet pools that offer thick accumulations of leaves, sticks and other organic debris.
The next time you seine bait for a stream-fishing trip, take a look at the occasional small catfish you net. Chances are it's not a fingerling catfish, but a madtom.
HANDLE WITH CARE!
These diminutive catfish can inflict a painful puncture wound with the spines on their pectoral and dorsal fins. Like all of Missouri's catfish species, madtoms have venom glands at the base of these fins. The glands secrete venom that becomes incorporated in the slime and cells that make up the spine.
Because madtoms are so small, it's difficult to avoid their tiny, sharp spines, especially if you are trying to impale them on a fishing hook. Many describe the pain that comes from being "horned" by a madtom as similar to a bee sting. Others claim it to be much worse. It's best to handle madtoms carefully.
MADTOMS IN HOME AQUARIUMS
Madtoms make ideal aquarium inhabitants. Even as adults, they are too small to eat most aquarium fish.
During the day, madtoms typically hide under rocks or other aquarium structures,with maybe only their whiskered chins sticking out. Place food in the aquarium, however, and they quickly swim out to feed.
Madtoms are particularly well suited for aquariums set up for native fish. Minnows,madtoms, darters and topminnows all adapt well to aquarium life and are resistant to the diseases that often plague tropical fish. With a valid Missouri fishing permit, you can possess up to 150 bait fish. However, you cannot collect or possess endangered or threatened species, such as mountain or Neosho madtoms.
The Neosho madtom has been collected only a few times from the Spring River just upstream from Kansas-Missouri border. You should avoid kick seining where mountain and Neosho madtoms are known to occur, and it's always important that you correctly identify the species of madtoms so you can release mountain or Neosho madtoms.
However, you have a good chance of collecting Missouri's other seven species of madtoms.
