鉴别

Diagnosed from other cyprinids in central and eastern Europe by having incomplete lateral line with about 8-12 pored scales, keel covered by scales between pelvic origin and anus, mouth superior, and 11-13½ branched anal rays (Ref. 59043). A small fish with large silvery scales and an inconspicuous intense silvery band along each side. Lateral line incomplete, sometimes absent, with perforated scales. Anal fin longer than dorsal fin. Mouth turns upwards. The lower edge of the body between the pelvic fins and the vent forms a sharp keel. The scales are very loosely attached and fall away if the fish is handled. Also Ref. 40476.

鉴定难易度 easy to distinguish from other species.
