Percina carbonaria
Texas logperch
Type Locality
Rio Salado (6km W San
Antonio), Texas (Baird and Girard 1853).
Etymology/Derivation of Scientific Name
Percina, “a small
perch;” carbonaria, “of or relating to charcoal”, perhaps referring
to black coloration on parts of the body and/or overall dusky coloration of
the species.
Synonymy
Pileoma carbonaria
Baird and Girard (1853).
Characters
Maximum size: 112 mm
SL (Morris and Page 1981).
Coloration: Dorsum and
side of the body are light olive; the underside is cream. Vertical bars on
sides of body with obvious constriction medially; bars expanded dorso- and
ventrolaterally; lateral bars wide, nine to 10 whole bars; midbars between
whole bars short, about half the length of whole bars; centers of the bar
are lighter in color than the edges. Medial spot at the base of the caudal
fin and the suborbital bar are black, well-developed. 1st dorsal fin dusky
black marginally and basally and in adults has orange submarginal band.
Breeding males dusky overall with an orange cast with black on breast, the
pelvic and anal fins, and branchiostegal membranes, and having bright orange
submarginal band on 1st dorsal fin (Page 1983; Hubbs et al.
1991). Differences in coloration between Guadalupe River and Colorado River
P. carbonaria are evident, in that P. carbonaria of Guadalupe
River often has a mottled pattern on upper sides and somewhat less intense
pigmentation in the breeding male; that of Colorado River may have lateral
bars fused dorsally (Stevenson 1968).
Counts: More than 77
scales in lateral line (Hubbs et al. 1991), 80-93 lateral scales (Page
1983); pored scales on caudal fin 0-3; scales above lateral line 8-12
(9-10); scales below lateral line 14-19 (15-18); transverse scales 25-32
(27-30); scales around caudal peduncle 27-37 (30-34); dorsal spines 12-16
(14-15); dorsal rays 13-16 (14-15); pectoral rays 12-15 (14); anal spines 2;
anal rays 9-12 (10-11); branchiostegal rays 6. Male has a row of 26-35
modified scales along belly midline (Page 1983). Morris and Page (1981)
compare differences in certain meristic counts between Guadalupe River and
Colorado River Percina carbonaria samples.
Body shape: Elongate
(Morris and Page 1981), subfusiform, compressed (Baird and Girard 1853);
body depth contained in standard length less than seven times; snout conical
extending beyond upper lip; upper jaw not extending as far as to below
middle of eye (Hubbs et al. 1991).
Mouth position:
External morphology:
Belly scaled (a narrow naked band may be present on midline); preopercle
smooth or weakly serrate (Hubbs et al. 1991); head with scales on cheeks
opercles and temporal regions (Morris and Page 1981).
Distribution (Native and Introduced)
U.S. distribution:
Texas distribution:
Occurs throughout the Edwards Plateau region of central Texas, north and
east to the Red River (the Brazos, Colorado, Guadalupe and San Antonio river
drainages; Morris and Page 1981). Warren et al. (2000) list the following
drainage units for the species: Brazos River unit, Colorado River unit, San
Antonio Bay unit (including minor coastal drainages west of mouth of
Colorado River to mouth of Nueces River). Species collected from the Bosque
River and Leon River watersheds within the Middle Brazos River Basin
(Armstrong 1998).
Abundance/Conservation status (Federal, State, NGO)
Populations in the southern
United States are currently stable (Warren et al. 2000).
Habitat Associations
Macrohabitat: Streams
(Morris and Page 1981); small to medium rivers (Page and Burr 1991).
Mesohabitat:
Hyperbenthic (Near 2002). Common in rocky riffles (Morris and Page 1981) and
runs (Page 1991). Percina carbonaria is a pollution intolerant
species (Armstrong 1998; Linam and Kleinsasser 1998).

Phylogeny and morphologically similar fishes
Percina carbonaria is
distinguished from certain members of subgenus Percina, including
P. caprodes, and P. macrolepida,
by combination of fully scaled nape; no prepectoral, breast (except
modified) or supraoccipital scales; modally 18 or 19 broad vertical bars
along side, bars constricted medially and expanded below lateral line and
dorsolaterally; orange submarginal in first dorsal fin of male and female;
breeding male with intensely black branchiostegal membranes, breast, pelvic
fins, and anal fin (Morris and Page 1981).
