The Green Sunfish
Description
The green sunfish, like warmouth, has a large mouth and a heavy, black bass body shape. The body is dark green, almost blue, dorsally, fading to lighter green on the sides, and yellow to white ventrally. Faint vertical bars are apparent on the sides. Some scales have turquoise spots. Lepomis, the generic name, is Greek and means "scaled gill cover." The species epithet cyanellus is also Greek and means "blue.

Life History
The green sunfish is a very versatile species, able to tolerate a wide range of environmental conditions, and tends to do very well when competition with other sunfish is minimal. Its ability to tolerate environmental extremes makes it ideal for survival in prairie streams where conditions are not stable, and it is often the first sunfish species to repopulate depleted areas. Green sunfish nest in shallow water colonies where nests are often closely packed. Gravel or rocky bottom sites are usually preferred for nest building. Spawning occurs in late spring, when water temperatures rise above 70°F, and may continue throughout the summer. Hybridization with other sunfish species is very common. Males aggressively defend their nests for 6-7 days after eggs are deposited, at which time fry are usually free-swimming. Because of their enormous reproductive potential, green sunfish often overpopulate small lakes and ponds. Adults feed on insects and small fish.
|
Distribution
Originally the distribution of green sunfish appears to have been limited to the central plains west of the Appalachian Mountains and east of the Rocky Mountains, including northeastern Mexico. However, due to introductions the species has become nearly ubiquitous in the United States with the exception of Florida and parts of the northwest.

The Longear Sunfish
Description
Lepomis, the generic name, is Greek and means "scaled gill cover." The species epithet megalotis is Greek and means "great ear." The name is derived from the fact that longear sunfish have an elongated opercle flap. This flap, always trimmed in white in adults, is unique and makes field identification relatively easy if hybridization has not occurred. Longear sunfish are quite colorful. Males are often bright orange or scarlet, and the head and fins usually have turquoise markings. Dorsal and anal fins, and their associated spines, are similar to those of redear sunfish.

Life History
Longear sunfish are primarily found in small streams and creeks. Like other sunfish they are often associated with vegetation, avoiding strong currents by inhabiting pools, inlets, and waters off the main stream channel. Spawning occurs throughout late spring and early summer. Males scoop nests out of gravel bars. Females are enticed to lay their eggs on a particular nest by a male who swims out to meet her, swimming around her rapidly and displaying his brilliant spawning colors. After the eggs have been laid, males chase the females away and guard the nest vigorously despite their small size, chasing away all intruders. Males may continue to guard the nest for a week or more after hatching, until larvae have dispersed. Insects and even small fish become part of the diet as fish approach adulthood. Longear sunfish rarely exceed six inches in length.
|
Habitat
Because of its small size, the species' importance to anglers derives in three ways. Since they are relatively easy to capture with simple, natural baits such as earthworms, longears are an important species for young anglers with little experience. Like most sunfish, they provide more than enough fight for their small size. Longears may feed on the surface, providing the fly fishermen with a challenge, and finally, they are often a prized bait fish for trotliners.
|
Distribution
Longear sunfish are restricted to freshwater areas west of the Appalachian Mountains. Scattered populations occur as far north and west as southern Quebec and Minnesota, and as far south and west as north central Mexico and New Mexico.

The Redear Sunfish
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).

Life History
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.
|
Habitat
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.
|
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.

The Bluegill
Description
Lepomis, the generic name, is Greek and means "scaled gill cover". The species epithet macrochirus is also Greek and means "large hand" which may refer to the body shape or its size. Bluegills may be distinguished from other sunfish by the dark spot at the base of the dorsal fin, vertical bars on their sides, and a relatively small mouth. The spiny dorsal fin usually has 10 spines (but may have as many as 11 or as few as 9), and is broadly connected to the soft dorsal. The anal fin has three spines. The back and upper sides are usually dark olive green blending to lavender, brown, copper, or orange on the sides, and reddish-orange or yellow on the belly. Colors are more intense in breeding males, and vertical bars may take on a reddish hue.
|
|
Life History
Bluegills begin spawning when water temperatures reach about 70°F. Spawning may peak in May or June, but continues until water temperatures cool in the fall. Because of their long spawning season, bluegills have very high reproductive potential, which often results in overpopulation in the face of low predation or low fishing pressure. Nests are created in shallow water, one to two feet in depth. Gravel substrate is preferred. Fifty or more nests may be crowded into a small area, thus creating a spawning bed. Males guard the nest until the eggs hatch and fry leave. Young fish feed on plankton, but as they grow the diet shifts to aquatic insects and their larvae. Up to 50% of their diet may consist of midge larvae.
|
Distribution
Bluegills appear to have been native to the eastern half of the United States, southeastern Canada and northeastern Mexico, exclusive of the coastal plain north of Virginia. Today, as a result of countless intentional as well as no doubt unintentional introductions, bluegill are found throughout the US and northern Mexico. Bluegills are found throughout Texas. Three subspecies are present: Lepomis macrochirus macrochirus which is native to the northeastern half of the state, Lepomis macrochirus speciosus which is native to the central, southern, and western portions of the state, and Lepomis macrochirus purpurescens, a native of Atlantic coast states which has been introduced widely as a sport and forage fish.
