Freshwater Fish Identification
Redear Sunfish
Lepomis microlophus
Other names: Shellcracker, Georgia bream, cherry gill, sunny, sun
perch Status: Texas nongame fish
Description
Lepomis, the generic name, is Greek and means "scaled gill cover."
The species epithet microlophus is Greek for "small nape." The redear
is a deep-bodied sunfish with a relatively small mouth. Color ranges from dark
olive green above to almost white on the belly. The sides are usually yellow to
green. The spinous dorsal fin, which is anterior to the soft dorsal fin, is
normally equipped with 10 spines, although 9 or 11 spines are sometimes
observed, and it is broadly connected to the soft dorsal fin. The anal fin has
three spines. The species' most distinct characteristic is the red edge on the
opercle ("ear") flap of the male (orange on the female). The opercle flap is
never greatly elongated as it is in species such as the redbreast sunfish
(Lepomis auritus) or the longear sunfish (L. megalotis).
Angling Importance
Unlike some other sunfish species, redears rarely approach the surface to
take flies or other artificial top baits. They may, however, be readily captured
using natural bait such as earthworms and grubs. Redear are often taken in early
summer when they are concentrated on spawning beds.
Biology
Redear sunfish often utilize snails as a major food item, hence the common
name "shellcracker." However, insect larvae and cladocerans may also be found in
their diet. The species is usually found near the bottom in warm water with
little current and abundant aquatic vegetation. Redears normally reach sexual
maturity by the end of their second year. They spawn during the warm months of
late spring and early summer, and in deeper water than most other sunfish,
congregating in spawning "beds." Nests are saucer-shaped depressions in gravel
or silt, and are sometimes so close they almost touch. There are usually one or
two peaks of activity during spawning season. Few individuals survive more than
six summers.
Distribution
Redear sunfish were originally found in the southeastern US from Texas north
to a line even with southern Illinois and east to the Atlantic Ocean. As a
result of introductions, the range has been expanded and now extends west into
New Mexico and north into Michigan, Ohio and Pennsylvania. In Texas the species
is native to the eastern two-thirds of the state from the Red River to the Rio
Grande. It has been widely introduced throughout the state.
