Field Guide

The flathead chub is a slender, silvery minnow with small eyes, sickle-shaped pectoral fins, and wedge-shaped head with a pointed snout. Native to Missouri's big rivers and their tributaries, it is now state endangered.

The golden shiner is a deep-bodied minnow with a greenish-olive back and a faint dusky stripe along the midline. It has a fleshy keel along the midline of the belly. It is widespread in Missouri.

The southern redbelly dace has two dusky stripes separated by a broad golden stripe along the side. The bellies of males turn brilliant red in spring. It lives in small creeks and spring branches of the Ozarks with permanent flow of cool, clear water and a gravel or sand bottom.

The Ozark minnow is small and slender, with a prominent dusky stripe along the midline that extends forward past the eye. It is one of the most common minnows in the Ozark uplands.

Found in only a few Missouri streams, the Topeka shiner is an endangered native minnow that has declined dramatically because of environmental pollution, siltation, and loss or alteration of habitat.

The bleeding shiner is restricted to the Ozarks. Males sport brilliant red during breeding season. Check your ID by noting the dark, crescent bar behind the gill cover and the dark stripe that abruptly narrows just behind the gill opening.

The hornyhead chub is a moderately large, slender minnow with a rather large, nearly horizontal mouth. Males commonly have bony projections on top of the head. Occurs in clear Ozark streams with permanent flow and clean gravel.

The southern cavefish has a long, flattened head without eyes. It is whitish-pink because it lacks pigmentation. The only other Missouri fish that lacks eyes is the Ozark cavefish.

The spring cavefish is the only cavefish in our state that has eyes, however small, and whose body is yellowish brown or brown; our other cavefishes lack eyes entirely and are pale and nearly colorless.

The central stoneroller is a brownish minnow with small eyes. The lower jaw has a flat, shelflike extension used to scrape algae from rocks. Found statewide, it is most active during the daytime.
