    All text below is derived from a January 2013 copy of Dr. Timothy Bonner's website at Texas State University. That content was derived primarily from published literature. We are aware of some conflicts with the museum record and the content below will evolve as the new, expanded UT and Texas State Fishes of Texas project team members are able to update it. We invite collaborations to improve and expand the species account content. Please contact us if you wish to help, or if you discover flaws in our species account content that you can address.

    Type Locality:

    Ohio River (Rafinesque 1819).

     

    Etymology/Derivation of Scientific Name

    Lepomis, Greek, meaning “scaled gill cover”; cyanellus, Greek, meaning “blue” (Pflieger 1975).

     

    Synonymy

    Lepomis cyanellus: Rafinesque 1819:420; Forbes and Richardson 1908:248-250; Smith 1965:9

    Telipomis cyanellus: Nelson 1876:37

    Characters

    Maximum size: Up to 250 mm TL (Lee 1980).

     

    Life colors: Dark spot at posterior base of dorsal fin; black spot on dorsal fin without a pale margin (Hubbs et al 1991). Head olivaceous; cheeks randomly spotted and streaked with bluish green; back olivaceous to brownish; sides greenish with 7-12 indistinct dark, vertical bars; opercle black with light margin; abdomen whitish yellow. Dorsal, caudal, and anal fins with a yellowish white border and a dark basal spot on second dorsal and anal; all fin membranes dusky with randomly scattered light spots. Yellowish white border of dorsal, caudal, and anal fins intensified in breeding male (Sublette et al. 1990). Dominant fish are generally lighter colored (Howard 1974). Color mutation is the Texas golden green sunfish, appearing golden in color (White 1971).

     

    Counts: 35-55 scales on complete lateral line; 3 anal spines; 6-13 dorsal fin spines; 6 or 7 branchiostegals (Hubbs et al 1991); 10-1 dorsal rays; 9-10 anal rays; 13-14 pectoral rays (Ross 2001).

     

    Body shape: Strongly compressed laterally (Sublette et al. 1990). Body depth usually contained two to two and one-half times in standard length (Hubbs et al 1991).

     

    Mouth position: Terminal oblique. Palantine teeth are present (Goldstein and Simon 1999), in older individuals (Sublette et al. 1990).

     

    External morphology: Gill rakers in adults long, when depressed reaching beyond base of second raker below; supramaxilla two-thirds width of maxilla; opercle stiff to its margin (not including membrane); posterior edge of opercle within opercular membrane smooth; pectoral fins short and rounded; pectoral fin contained 3.75 or more times in standard length; lateral line present; scales ctenoid (Hubbs et al 1991).

     

    Internal morphology: Intestine long and well differentiated; peritoneum white to silvery; pyloric caeca present (Goldstein and Simon 1999).

     

    Distribution (Native and Introduced)

    U.S. distribution: Restricted originally to east-central North America, west of the Appalachians chain southward into Mexico; widely introduced elsewhere in United States (Lee 1980).

     

    Texas distribution: Occurs throughout the state (Hubbs et al 1991). Warren et al. (2000) list the following drainage units for distribution of Lepomis cyanellus in the state: Red River (from the mouth upstream to and including the Kiamichi River), Sabine Lake (including minor coastal drainages west to Galveston Bay), Galveston Bay (including minor coastal drainages west to mouth of Brazos River), Brazos River, Colorado River, San Antonio Bay (including minor coastal drainages west of mouth of Colorado River to mouth of Nueces River), Nueces River.

     

    Abundance/Conservation status (Federal, State, NGO)

    Populations in the southern United States are currently secure (Warren et al. 2000).

     

    Habitat Associations

    Macrohabitat: Ecologically tolerant of many habitats, but does not normally occur in brackish water (Lee 1980). Common in ponds and streams, lakes, and in areas of river with little flow (Sublette 1990; Ross 2001).

     

    Mesohabitat: Preferred sites have low velocity within the temperature range of 26-31 degrees C (Stuber et al. 1982). Laboratory studies indicate a preferred temperature of 28.2 degrees C (Beitenger et al. 1975). Species will tolerate alkalinities up to 2,000 mg/1. In California area, abundant in small intermittent streams at lower elevations, especially in warm, turbid, muddy-bottomed pools with large amounts of vegetation and with Micropterus salmoides and Gambusia affinis (Carlander1977). Collected from Sister Grove Creek, an intermittent prairie stream in N-central Texas (Meador and Matthews 1992). Lepomis cyanellus common in many of the clearer tributaries of Lake Texoma (Oklahoma and Texas; Riggs and Bonn 1959). Captured in both the saline and freshwater reaches of the Pecos River, Texas, but highest capture rate was in freshwater reach (Rhodes and Hubbs 1992). Baughman (1946) collected L. cyanellus from residual pools of a recently drained rice canal near Barbour’s Hill (Chambers Co.), Texas.

     

    Biology

    Spawning Season: Begins in spring and continues until late summer in water temperatures between 15-31 degrees C (Hubbs and Cooper 1935; Tin 1982; Stuber et al. 1982).

     

    Spawning Location:  Nest spawners. Polyphils; miscellaneous substrate and material nesters that have adhesive eggs either attached or occur in clusters on any available substrate (Simon 1999). Eggs are laid in nests scooped out of gravel or sandy silt by the male in depths of 4-355 cm (Stuber et al. 1982). Nests built in large colonies in less than 40 cm water, on gravel with maximum sunshine (Carlander 1977). Nests seldom located in water deeper than 35 cm; small males may construct nests in water as shallow as 4 cm; nests built in rocks, logs, clumps of grass, or occasionally abandoned sunfish nests (Hunter 1963).

     

    Reproductive Strategy: Males fan out a depression in shallow water. Males actively court females by rushing out toward them, and then returning rapidly to the nest. Gruntlike sounds produced by nesting males to attract females (Gerald 1971, Ross 2001). Guarders (Simon 1999); nests are defended by male until larvae emerge (Sublette et al. 1990).

     

    Fecundity: Fertilized eggs are demersal, adhesive, and range from 1.0-1.4 mm in diameter. Larvae hatch at about 4.2 mm TL (Meyer 1970; Taubert 1977).

     

    Age at maturation: Occurs at age one in Missouri, Illinois, Iowa, but not until age three in Michigan; mature males reported as 76 mm and 45 mm and females at 66 mm and 6 – 10 g (Carlander 1977). Texas golden green sunfish reaches sexual maturity in less than 6 months (White 1971).

     

    Migration:

     

    Longevity: In Bull Shoals Reservoir (Arkansas and Missouri) no fish lived to the end of their 6th year (Applegate et al. 1967). 7.5 years in captivity (Carlander 1977).

     

    Growth and Population Structure: In Bull Shoals Reservoir (Arkansas and Missouri) Lepomis cyanellus reached 45.7 mm TL after one year and 71.1 mm, 91.4 mm, 109.2 mm, and 121.9 mm TL for years 2-5, respectively (Applegate et al. 1967). Males generally larger than females (Hubbs and Cooper 1935). A study showed most older fish were males (Carlander 1977). Lepomis cyanellus have a well-developed social system with dominant and subordinate individuals. Dominant fish are generally lighter colored and are usually the largest individuals (Howard 1974).

     

    Food habits: Trophic classifications: Invertivore/carnivore; drift/whole body feeder. Trophic mode: water column/ambush. Main foods are insects, mollusks, and small fishes (Goldstein and Simon 1999). Species has larger mouth than most other sunfish of same size and eats larger food items. Young feed on zooplankton. Adults feed on insects, crayfish, terrestrial arthropods, Micropterus salmoides eggs and fry, other fishes including Gambusia affinis (Carlander 1977); aquatic and terrestrial insects appear to be most important food item (Stuber et al. 1982). In Bull Shoals Reservoir (Arkansas and Missouri) fish smaller than 48 mm TL feed primarily on aquatic insects and small crustaceans (copepods and cladocerans); from 51-76 mm TL, major prey include large aquatic insects such as mayfly larvae; fish longer than 102 mm TL feed heavily on large crustaceans such as crayfishes (Applegate et al. 1967); Applegate (1966) noted L. cyanellus feeding on bryozoans (Fredericella sultana). In streams where L. cyanellus is not native, species has been implicated in causing the disappearance of several native minnows (Lemly 1985).

     

    Phylogeny and morphologically similar fishes

    Lepomis cyanellus possibly most primitive species of typical Lepomis. It is similar to L. gulosus (warmouth; Branson and Moore 1962; Lee 1980), but may be separated from this species, L. megalotis (longear sunfish), and L. macrochirus (bluegill) by a large mouth; short, rounded pectoral fins; anal fins with three spines; and the tongue (except in older individuals) and pterygoids without teeth (Sublette et al. 1991). Known to hybridize with at least five other Lepomis (Lee 1980), including L. macrochirus (bluegill; Childers and Bennett 1961), L. megalotis (longear sunfish), L. humilis (orangespotted sunfish), L. auritis (redbreast sunfish), and L. microlophus (redear sunfish; Childers 1967).

     

    Host Records

    Commercial or Environmental Importance

    White (1971) notes the golden color of Texas golden green sunfish may make it particularly susceptible to predation and a good forage fish. Lepomis cyanellus found to be major food source for Micropterus salmoides (largemouth bass) in a desert impoundment (Biggins 1968). Usually individuals do not become large enough to interest anglers. Species is easily handled and make good bioassay animals (Carlander 1977).
