Source-derived summary

The robust redhorse (Moxostoma robustum) is a redhorse-type fish that lives in the freshwater streams of the eastern United States. It was previously called the smallfin redhorse.

Taxonomy

Using a 6-pound (2.7 kg) specimen from the Yadkin River of North Carolina, naturalist Edward Drinker Cope first described the robust redhorse as Ptychostomus robustus in 1870. The original specimen was lost or destroyed, and by the late 19th century, all mention of the robust redhorse had ceased. It was thought to be extinct until several unidentified fish specimens were collected from the Savannah River and Pee Dee River in 1980 and 1985. In August 1991, biologists with the Georgia Department of Natural Resources officially rediscovered the species when five specimens of the fish were collected in the Oconee River, and identified as robust redhorse.

Description

M. robustum is a large, fairly long-living animal compared to other members of its family;

the fish can weigh up to 17 pounds (7.7 kg) and live for up to 27 years, although it averages 25 inches (64 cm) in length and 9 pounds (4.1 kg) in weight. M. robustum's body is thick, or "robust", its fins are rose-colored, and it has a fleshy lower lip.

Distribution and habitat

M. robustum is found in the eastern United States from the Cape Fear River drainage in North Carolina's Peedee River drainage, south to the Oconee River system, part of Georgia's Altamaha River drainage.

They live in both rocky and silty pools or less turbulent areas of small and medium rivers, and are also found in reservoirs and other water impoundments.

Editorial summary

The public source identifies “Robust redhorse” as species of fish. This brief keeps that definition visible, then builds a research path around Robust, redhorse and species.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current lead gives the account dated anchors—1870, 1980, 1985, 1991—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Robust, redhorse and species providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Robust redhorse”, the useful work is to connect “species of fish” to the records capable of establishing context and consequence.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 21, 2026. The linked authority identifier is Q3763241. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1870, 1980, 1985 and 1991.

Critical limits

Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
