Diagnosis |
Body stout, thick-set, caudal peduncle thick and short (Ref. 1998). Head without scales (Ref. 39167, 1998), broadly triangular (Ref. 1998), interorbital space broad, snout longer than eye diameter, maxillary reaching posterior nostril or not quite to eye (Ref. 39166), barbels lacking on upper jaw (Ref. 39104, 1998). Lateral line complete. Dorsal and anal fins with serrate bony spines, pelvic fins short, broad and thoracic. Nuptial tubercles of male fine, on opercle, sometimes on back and a few on pectoral fins. Hybridize readily with carp, hybrids intermediate in most characteristics (Ref. 1998). Caudal fin with 17-19 rays (Ref. 2196). Last simple anal ray osseous and serrated posteriorly; no barbels (Ref. 43281). Pigmentation: Wild-caught specimens, olive brown (Ref. 39168, 39104), slate olive, olive green, with a bronze sheen (Ref. 39104), silvery, grayish yellowish, gray-silver (Ref. 39169), through gold (often with black blotches) to creamy white (Ref. 1998); yellowish white or white below. Cultured forms vary through scarlet, red-pink, silver, brown, white, black and combinations of these colors (Ref. 39104). |
