Fresh Water Fish Identification
COMMON NAMES: Smallmouth bass, Brown bass, Brownie, Smallie
SCIENTIFIC NAME: Micropterus dolomieui dolomieui
IDENTIFICATION: Smallmouth bass look very similar to largemouth bass and spotted bass. The distinguishing characteristic is the mouth. When closed, the mouth does not extend beyond the rear border of the eye. Color varies from yellow-green to olive-green with a bronze reflection. The sides are faintly barred.
RANGE AND HABITAT: Smallmouth bass thrive in streams with gravel or rock bottoms with a visible current. Smallmouth also do well in the reef areas and rocky shorelines of Lake Erie, especially in the islands area near Sandusky Bay.
ADULT SIZE: Average smallmouth bass are between 1 to 2 pounds, and range from 12 to 15 inches in length. The state record smallmouth bass weighed 9 pounds and 8 ounces.
Distribution: Smallmouth bass originally ranged north into Minnesota and southern Quebec, south to the Tennessee River in Alabama and west to eastern Oklahoma and southwestern Arkansas. Today there are few states, east or west of the Rocky Mountains, where populations have not become established. Florida and Louisiana are apparently free of smallmouth bass.
LIFE HISTORY: Smallmouth bass prefer large clear-water lakes (greater than 100 acres, more than 30 feet deep) and cool streams with clear water and gravel substrate. In small streams a fish's activity may be limited to just one stream pool or extend into several. Spawning occurs in the spring. Smallmouth bass spawn in May and early June when water temperatures range from 55 to 65 ° F. Nests are built in gravel or hard bottom substrates in 2 to 20 feet of water in lakes, downstream from boulders or some other obstruction that offers protection against strong current in streams. Mature females may contain 2000-15,000 golden yellow eggs. Males may spawn with several females on a single nest. On average each nest contains about 2,500 eggs, but nests may contain as many as 10,000 eggs. Eggs hatch in about 10 days if water temperatures are in the mid-50's (°F), but can hatch in 2-3 days if temperatures are in the mid-70's (°F). Males guard the nest from the time eggs are laid until fry begin to disperse, a period of up to a month. As in other black bass, fry begin to feed on zooplankton, switching to insect larvae and finally fish and crayfish as they grow.
FISHING METHODS: Fly fishing, baitcasting, and spincasting are popular means of catching smallmouth bass. Live-bait anglers have good success in streams using hellgrammites, soft craws and minnows. During May, many smallmouth bass are caught in small tributary streams. The Bass Islands area of Lake Erie is one of the best smallmouth bass fishing spots in the Midwest. The best time to fish there is late spring and late summer. Emerald shiners, small crayfish, and a variety of artificial lures produce good results when fished over reefs, sandbars or gravel bars in 2 to 10 feet of water.
