Краткое описание определительные ключи | морфология | морфометрия

членистые (мягкие) лучи спинного плавника (общее число) : 10 - 11; членистые (мягкие) лучи анального плавника: 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).

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).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01148 (0.00455 - 0.02896), b=3.03 (2.81 - 3.25), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.1   ±0.0 se; based on diet studies.
устойчивость к внешним воздействиям (Ref. 120179):  средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (tm=3-4).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (20 of 100).
Категория цены (Ref. 80766):   Unknown.
