Field Guide

The rainbow darter is a common and characteristic darter in the Ozarks. Where it occurs in our state, it is the most abundant darter in most streams of all sizes. Breeding males are brilliantly colored with reddish orange red and greenish blue.

In Missouri, the mottled sculpin occurs in the Niangua River system, some tributaries of the Lake of the Ozarks, the Meramec, Gasconade, and Osage river systems, and some other eastern Ozark streams. It is most similar to the Ozark and knobfin sculpins.

The Ozark sculpin occurs only in the Osage, Gasconade, and Black river systems, in the Ozarks of southern Missouri and northern Arkansas. It is most similar to the mottled and knobfin sculpins.

The knobfin sculpin occurs only in the Current, Eleven Point, and White river drainages in the Ozarks of southern Missouri and northern Arkansas. Until 2010, it was considered the same as the Ozark sculpin.

In Missouri, the brown bullhead occurs in quiet, clear waters in wildlife refuges in southeast Missouri. Elsewhere in the state, it is stocked and possibly escapes. It has mottled sides and an elongated barbel at the corner of the mouth.

The white catfish is often stocked in fee-fishing lakes and other private waters. It sometimes escapes into natural stream systems. Unlike our other bullheads, it has a moderately (though not deeply) forked tail fin.
