Family Cyprinidae

Distribution: North America (northern Canada to southern Mexico), Africa, and Eurasia . Pharynx with 1-3 rows of teeth, each row with a maximum of 8 teeth. Usually thin lips , plicae or papillae absent; mouth sometimes suckerlike (Garra and Labeo). With or without barbels . Premaxilla usually borders the upper jaw making the maxilla entirely or almost entirely excluded from the gape. Usually protrusible upper jaw. Dorsal fin with spinelike rays in some. Primitive number of chromosomes 2n=50, some with 48; polyploidy exists. Maximum length at least 2.5 m to probably 3 m in Catlocarpio siamensis; many species less than 5 cm. Mainly non-guarders, but in some species males build nests and/or protect the eggs .The family Cyprinidae belongs to the Class Actinopterygii (ray-finned fishes ) and the Order Cypriniformes. It contains 210 genera and 2010 species. It may be found in Brackish , and Freshwater environments and is primarily Primary freshwater. Many members of this family are used in the aquarium trade. Reproductively, most members of this family are nonguarders. The main mode of swimming of adult fish in this family is subcarangiform. Compared with other fish, the activity level of this family tends to be normal. Members of this family have been dated back to the Eocene epoch of the Tertiary period. This family may be found from 70° n to 34° s and 150° w to 170° e. Etymology of this family name : Greek, kyprinos = goldfish .

Physical Description

Species Rhinichthys cataractae

Body: Mouth and Snout: Mouth inferior without any teeth. Inconspicuous barbels at corners of the mouth. Thick fleshy lips with frenum connecting snout with lip. Snout greatly overhangs mouth. Body Pattern : Sides brown, dark olive, or dark gray with darker blotches and mottling often coalescing into an irregular lateral stripe anteriorly. Cream, silvery or yellow-white belly. Fins pigmented . Body Shape : Fusiform and elongate , almost round in cross-section with ventral area slightly dorso-ventrally flattened. Typical adult size is 75-100 mm TL (3-4 in), with a maximum of about 140 mm (5.5 in).

Fins: Forked tail. Single dorsal fin with 8 rays and no spines. Pelvic fins abdominal . No adipose fin . Anal fin with 7 rays and no spines.

Distinguishing characteristics: Inferior mouth with fleshy lips and inconspicuous barbels at the corners. Frenum connection upper lip to snout. Compaired to blacknose dace, snout greatly overhangs mouth and body is less deep and more elongated. 61-75 cycloid lateral scales . About 54 scale rows around body. See also similar species information.

Breeding adults: Males have small tubercles on head , scales, and pectoral . Both sexes get salmon, orange, or yellowish pigment around mouth, cheek, base of pectoral, pelvic , and caudal fin.

Juveniles : Similar to adults, but typically lateral stripe more pronouced, caudal spot present.

Habitat

Inhabit rubble and gravel riffles (sometimes runs and pools ) of fast creeks and small to medium rivers ; also in rocky shores of lakes [2]. Young up to 4 months are pelagic[1].

Typically found at an altitude of 0 to 5,134 meters (0 to 16,844 feet).[3]

Biome: Fresh water . Demersal .
