Field Guide

The crystal darter is Endangered in Missouri. Formerly known from many river drainages in the east-central and southeastern parts of our state, this pale, very slender darter apparently now lives only in the Gasconade and Black rivers.

The greenside darter is one of our largest darters. It has olive to yellow sides and back with scattered red spots and vertical blotches often arranged in a V or W pattern. It is one of the most abundant and widespread darters in the Ozarks.

Two small black spots at the base of the tail fin distinguish the Niangua darter from all other darters in Missouri. Known from only a few tributaries of the Osage River, this dainty, colorful fish is a nationally threatened species.

The common shiner is mostly found in central and west-central Missouri in short, direct tributaries of the Missouri River. It is very similar to the striped shiner but lacks dusty sprinkles of pigment on its chin and (except for breeding males) lacks dark lines on the upper part of the body.

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 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.
