Leuciscus orientalis Nordmann, 1840 is considered valid in Eschmeyer (CofF ver. May 2011: Ref. 86870). This is allocated to Squalius in Ref. 84537, a valid name, but secondary homonym Squalius orientalis Heckel, 1847 needs a replacement name.

Differs from its congeners in France, North, Baltic, Arctic, Black and Caspian Sea basins by the possession of the following characters: dorsal profile with a well-marked discontinuity between head and trunk; a row of black pigments along free margin of each flank scale, forming a regular reticulate pattern, with no or very few pigments on central part of scales; anal and pelvic fins orange to red; dorsal fin with 8½ branched rays; anal fin with 8½ branched rays (rarely 9½); scales on lateral line 40-45 + 2-3; mouth terminal, with well marked chin; lower jaw tip not included in the upper lip; interorbital distance 37-42% HL; postorbital distance 47-51% HL; eye diameter 17-22% HL, 1.5-2.3 times in snout length; body depth 22-27% SL; lower jaw long, length greater than depth of operculum; iris whitish; pharyngeal teeth 2,5-5,2; in stretched anal fin of individuals larger than about 15 cm SL, distance between tips of first and last branched rays usually greater than caudal peduncle depth (Ref. 59043). Caudal fin with 19 rays (Ref. 2196).
尾鳍有 19个鳍条。 (参考文献 2196)

Most abundant in small rivers and large streams of barbel zone with riffles and pools. Found along shores of slow-flowing lowland rivers, even in very small mountain streams, and in large lake, undertaking spawning migration to inflowing streams. Adults are solitary while juveniles occur in groups. Feeding larvae and juveniles live in very shallow shoreline habitats. Feed on a wide variety of aquatic and terrestrial animals and plant material. Large individuals prey predominantly on fishes. Breed in fast-flowing water above gravel bottom, rarely among submerged vegetation. Often form fertile hybrids with Alburnus alburnus (Ref. 59043). Popular with amateur sport fishermen. Can be caught with various baits and lures. The flesh is of poor quality (Ref. 38587).

Life cycle and mating behavior 成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
Spawning occurs in fast-flowing water above gravel bottom, rarely among submerged vegetation. Female spawn more than once during a season, individual females spawn with several males. Males assemble at spawning site and follow ripe females, often with much splashing, to shallow riffles. Females lays sticky eggs into the gravel (Ref. 59043). Pale yellow eggs are found attached to gravel, weed and stones in flowing water (Ref. 41678).歐亞大陸: 在從窩瓦河與烏拉河到伊朗的里海流域的西方與底格里斯河-幼發拉底河流域, 廣泛分佈於北海的流域，波羅的海，黑海與亞速海。
