How to recognise it
The Tadpole Madtom (Noturus gyrinus) is a small catfish known for its distinctive features. It has a slender, elongated body that typically measures between 3 to 5 inches in length. The coloration is usually a dark olive or brown on the back, fading to a lighter shade on the belly. The body is covered in small, dark spots that can vary in intensity.
Field marks include a broad, flattened head and a slightly forked tail. The pectoral fins are spiny and have a dark coloration. The mouth is small and located on the underside of the head, equipped with barbels that help in sensing food. The Tadpole Madtom is often confused with the Stonecat (Noturus flavus). The key detail that separates them is the Tadpole Madtom's more slender body shape compared to the stockier Stonecat.
Where it lives
The Tadpole Madtom is primarily found in the eastern United States. Its range extends from the Great Lakes region down to the Gulf of Mexico, including states like Ohio, Kentucky, and Alabama. This species prefers freshwater habitats such as streams, rivers, and ponds.
In terms of water type, Tadpole Madtoms thrive in slow-moving waters with plenty of cover, such as submerged logs, rocks, and vegetation. They are typically found at depths ranging from 1 to 10 feet. During warmer months, they may move into shallower areas, while in colder months, they often retreat to deeper, more stable waters.
When it bites
Tadpole Madtoms are most active from late spring to early fall, particularly from May to September. They prefer water temperatures between 70 to 80 degrees F for optimal feeding. The best times to fish for them are during dawn and dusk when they are most active.
Weather can influence their feeding behavior. A passing cold front may trigger increased activity, while high winds can make them less likely to bite. A full moon can also enhance their feeding, as the increased light encourages them to venture out more.
How to catch it
To catch Tadpole Madtoms, anglers can use light tackle with a 4 to 6-pound test line. A small hook, size 8 to 10, is recommended. Common rigs include a simple bobber rig or a bottom rig with a small weight to keep the bait near the bottom.
Effective baits include nightcrawlers, small minnows, and soft plastics in natural colors like brown or green. When using lures, small jigs or spinners in sizes 1/16 to 1/8 ounce can be effective. Cast near submerged structures or under overhanging vegetation, and retrieve slowly to mimic natural prey.
Size, age and the table
The typical size of a Tadpole Madtom that anglers encounter is around 3 to 5 inches. A trophy-sized specimen is generally considered to be over 6 inches. They grow relatively quickly, reaching maturity in about 2 years, and can live up to 4 years in the wild.
While Tadpole Madtoms are not commonly sought after for eating, they can be consumed. Their flesh is mild and delicate. If you choose to keep them, handle them carefully to avoid injury. For catch and release, ensure they are returned to the water promptly to minimize stress and increase survival rates.
