1. Smallmouth Bass (Micropterus dolomieu) a.k.a. Smallmouth; Smallie; bronzeback; brown bass; redeye; mountain trout

2. Identification: Bronze to dark olive dorsally; pale yellow to white ventrally; black mottling on back with vertical bars on side. Can reach a length of 69cm. Young can be identified by their tri-colored tail (yellow, black, white). Distribution: Occurs throughout most of Iowa. Absent from SW 1/3 of the state, and most abundant NE portion of the state. Fishbase Pictures Iowa DNR

3. Distinguishing from Similar Species: Smallmouth bass – mouth doesn’t extend past eye; tooth patch on tongue; no mid-lateral stripe; has vertical bars on side; YOY have tri-colored tail. Largemouth bass – mouth extends well past the eye; no tooth patch on tongue; broad black mid-lateral stripe; no vertical bars on side; found state- wide. Spotted Bass – mouth doesn’t extend past eye; has tooth patch on tongue; black mid-lateral stripe; no vertical bars on side; YOY have tri-colored tail; in IA it is only found in Lake Macbride. Fishbase Pictures Google Images Fishbase Pictures

4. Habitat: Clear to slightly turbid streams and rivers, over gravel or boulder laden substrate; shallow rocky areas of lakes and reservoirs (reefs, windblown points, etc.). Diet: Young of year (YOY) start on microcrustaceans, as growth proceeds diet mainly consists of aquatic insects, and finally graduates to macroinvertabrates and fishes. Insectivorous as larvae, and mainly piscivorous as adults. Greg Gelwicks Google Images Fishbase Pictures

5. Reproduction: Spawning occurs at temperatures between 16-21°C in waters ranging in depth from 1-6m depending upon clarity. Male fans a bed for female to lay eggs. Female may lay eggs in several different nests; number of eggs varies between 2,000-10,000. Male stays on bed to guard eggs and young. Conservation Status: Common in IA. Gamefish status. Length and bag limits exist in IA to conserve sport fishery.

6. Economic/Recreational Value: Important gamefish, and provides an additional sport fishery in IA. Ecological Importance: Important predator; quite often the top carnivore in many of Iowa’s small interior streams. Google Images
