Centrarchus macropterus
flier
Type Locality
Charleston, SC (Lacepede
1802).
Etymology/Derivation of Scientific Name
Centrarchus from the
Greek, kentron meaning “spine,” archos, meaning “anus,” in
reference to the development of the anal spines; macropterus, Greek,
meaning “long fin” (Pflieger 1975).
Synonymy
Labrus macropterus
Lacepède 1802:432 in Eschmeyer 1990.
Centrarchus irideus
Hay 1881:63; Hildebrand and Towers 1928:130; Cook 1959:176.
Characters
Maximum size: In
Virginia, it reaches 245mm (9.6 in) with an angler’s report of a 356 mm TL
fish (Jenkins and Burkhead 1994).
Coloration: The sides
are scattered with dark spots, the belly is light colored, and the back is
olive. The eye line is nearly vertical and continues ventrally as a
suborbital bar or teardrop. Small fish (less than about 45 mm SL) have a
distinct ocellus (dark spot surrounded by red or orange) on the soft dorsal
fin. Median fins are dusky with light reticulations (Ross 2001).
Pharyngeal teeth count:
Counts: LS 36-42.
Dorsal fin with 11-13 spines and 14-12 soft rays. Anal fin with 7-9 spines
and14-16 soft rays. Pectoral fin rays 12-14 (Etnier and Starnes 1993).
Body shape: Small
strongly compressed sunfish (Ross 2001).
Mouth position:
Oblique and moderate in size (Carr and Goin 1959).
External morphology:
Anal fin with seven to eight spines and 13 to 15 soft rays; more than 24
gill rakers on first arch; preopercle finely serrate; Eleven to thirteen
dorsal fin spines; five to eight anal spines; six to thirteen dorsal fin
spines; lateral line present; scales ctenoid; six or seven brachiostegels; (Hubbs
et al. 1991). Gill rakers long and slender, 30-35. Brachiostegal rays 7.
Vertebrae 31 (Etnier and Starnes 1993).
Distribution (Native and Introduced)
U.S. distribution:
Found in Atlantic coastal drainages extending from Virginia across Gulf
coastal plain to Texas and extending North through the Mississippi Basin to
Southern Illinois (Hubbs et al. 1991). Eastern Virginia south to
north-central Florida and throughout much of the Gulf coastal plain (to
eastern Texas) and Mississippi Valley, North to Southern Illinois. Original
status of southern Maryland population uncertain but may be introduced (Lee
and Gilbert 1980).
Texas distribution:
This species is restricted in the state to lowland streams in Eastern Texas
including Sabine, Neches, and San Jacinto drainages (Hubbs et al. 1991).
Abundance/Conservation status (Federal, State, NGO)
Not listed as threatened or
endangered by Texas Parks and Wildlife Department
(2006). Populations are
currently stable in the southern United States (Warren et al. 2000).
Habitat Associations
Macrohabitat: Sluggish
lowland habitats and clear heavily vegetated waters (Lee and Gilbert 1980).
In Village Creek, a blackwater stream of the Gulf coastal plain in east
Texas, the species was relatively rare and found exclusively in backwaters,
none being collected during the winter (Moriarty and Winemiller 1997).
Mesohabitat:
Apparently, fliers do not do well in neutral to alkaline waters, and
populations seem to be lower in areas with abundant bluegill or green
sunfish populations (Ross 2001).
Biology
Spawning season:
Breeding usually occurs March to May (14-17° C) but reported as early as
February (Lee and Gilbert 1980).
Spawning habitat: In
Missouri, Conley (1966) noted that gravid females were collected from a
variety of habitats ranging from debris filled ditches with soft bottoms, to
streams with gravel bottoms, to isolated borrow pits filled with heavy
stands of vegetation; in water conditions ranging from clear to very turbid
and from stagnant to a free-flowing situation.
Reproductive strategy: Lithophils; rock and gravel nesters that have
spherical or elliptical egg envelopes that are adhesive (Simon 1999). Nests
are spaced fairly close together (Carlander 1977). Lawrence (1957. Data for
Handb. Biol. Data: 1-29) discussed colonial nesting, guarding of nest and
fry, winter schooling; nest in colonies and males guard fry (Carlander
1977).
Fecundity: Number of
mature eggs produced by a female ranges from 1,900 to 37,500 in fish of
70-190 mm TL (Carlander 1977).
Age at maturation: One
year of age and an average length of 70 mm (Conley 1966).
Migration:
Growth and population
structure: At the end of one year fish averaged about 40 mm TL and are
70.6 mm, 99.8 mm, 111.8 mm, 150.9 mm, 163.7 mm, and 183.7 mm TL at the end
of ages 2-7, respectively (Carlander 1977).
Longevity: Fliers may
reach their eighth year (Carlander 1977).
Food habits:
Invertivore: feed heavily on Hemiptera and Corixidae (Simon 1999).
Phylogeny and morphologically similar fishes
Centrarchus is the
sister group to Archoplites, and together these form the sister clade
to Promoxis (Wainright and Lauder 1992; Mabee 1993).
The crappies (genus Promoxis)
are similar in body form and coloration, differences occur in dorsal spines,
fliers having 11 or more, compared to crappies (6-8). Crappies and all other
sunfishes have only 6 or fewer anal spines, while fliers have 7 or more (Etnier
and Starnes 1993).
Host Records
Trematoda: Phyllidostomum
pearsei, Posthodiplostimum minimum; Cestoda: Proteocephalus sp.;
Nemtoda: Spiroxys sp., Agamonema sp. (Arnold et al. 1967); Nematoda:
Contracaecum spiculigerum; Acanthocephala: Neoechinoryhnchus
cylindratus; Crustacea: Ergasilus caeruleus (Hoffman 1967).
Commercial or Environmental Importance
Conley (1966) states that
value of the species in the field of food and sport fishes is restricted to
the extent to which it is utilized as food by the carnivorous fishes that
are especially valued by the angler.
