Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt): 10-11; Afterflossenweichstrahlen: 9 - 10. Moderately compressed body, deepest in front of dorsal fin; strong tapering to narrow caudal peduncle; large, forked caudal fin; wide head; subterminal mouth; hard plate on lower jaw; large eye; dorsal-fin origin over pelvic-fin origin; rounded, protruding snout; decurved, complete lateral line with 85-93 scales; long intestine (at least twice length of body) ; black peritoneum; dorsal fin with 10-11 rays; anal fin with 9-10 rays; pharyngeal teeth 0,4-4,0 to 0,5-5,0; gray above, brassy silver side; yellow to brown fins; large individuals with gray dorsal and caudal fins, orange at pectoral and pelvic-fin bases (Ref. 86798). Tail large and flaring. Lower jaw bears a sharp edge, nearly square when viewed from beneath. Sharp part of lip consist of cornified epithelium which is sometimes slightly calcified. Internal to the fleshy upper lip is a small, hard plate upon which the lower lip bears. Young fish have a more rounded lower lip, when viewed either laterally or from below. Digestive tract in adults is about twice the length of the body, with most of its length consisting of a coiled section posterior to the entry of the bile duct (Ref. 52680).

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Occurs in flowing pools and runs over sand and gravel in creeks and small to medium rivers; also in margins of lakes (Ref. 86798). Adults feed mainly on diatoms, also on filamentous algae; young feed on surface insects (Ref. 1998).
