Issue
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.

زيست شناسي     واژه نامه (بعنوان مثال epibenthic)

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 بلوغ | تولید مثل | تخم ریزی | تخم ها | Fecundity | توزاد ( لارو)

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).
