How to recognise it
The River Redhorse (Moxostoma carinatum) is a distinctive freshwater fish. It has a streamlined body that can reach lengths of up to 30 inches and weights of around 10 pounds. Its coloration is typically a bronze or olive-green on the back, fading to a lighter, silvery belly. The fins are usually a reddish or orange hue, especially the tail fin. The mouth is subterminal, with thick lips adapted for feeding on the bottom.
This species is often confused with the Greater Redhorse (Moxostoma valenciennesi). The key detail that separates them is the presence of a pronounced keel along the belly of the River Redhorse, which is absent in the Greater Redhorse.
Where it lives
The River Redhorse is found primarily in the eastern United States, ranging from the Great Lakes region down to the Gulf Coast. It prefers large rivers and streams with moderate to swift currents. This species is often found in depths ranging from 3 to 15 feet. During spring and summer, it tends to inhabit areas with rocky or gravel substrates, while in the fall and winter, it may move to deeper pools with slower currents for shelter.
When it bites
The River Redhorse is most active from April to October. It prefers water temperatures between 60 and 75 degrees F. Early morning and late afternoon are the best times to fish for them. Weather changes, such as a passing front or increased wind, can trigger feeding activity. A full moon may also enhance their feeding behavior, making them more likely to bite during the night.
How to catch it
Effective rigs for catching River Redhorse include slip sinker rigs and Carolina rigs. Use baits like nightcrawlers, cut bait, or small minnows, typically in sizes ranging from 4 to 6 inches. Bright colors like chartreuse or orange can be effective for lures. A 10 to 15-pound test line is recommended, with hooks sized between 1/0 and 3/0. Cast near rocky structures, submerged logs, or current breaks, and allow the bait to settle on the bottom. Retrieve slowly, occasionally lifting the bait to mimic natural movement.
Size, age and the table
Anglers typically encounter River Redhorse in the 18 to 24-inch range. A trophy specimen is generally considered to be over 25 inches. Growth rates can vary, but they can reach maturity in 3 to 5 years. The lifespan of a River Redhorse can extend up to 10 years. While they are edible, their taste is often described as mild. Proper handling is crucial to ensure survival after catch and release, so use wet hands or a wet cloth when handling them to protect their slime layer.
