The barbel steed, Hemibarbus labeo, is a cyprinid widespread in eastern Asia between the Yangtze and Amur river basins. A predominantly riverine fish of clear, well-oxygenated running water, it forms schools just above the substrate as an adult, and some populations make annual spawning migrations. Adults lack dark spots on the body and have a long snout and well-developed lips.

Etymology

Edit

Hemibarbus: from the Ancient Greek ἡμι- (hēmi-), meaning 'half', and the generic name Barbus, to which members appear similar.

labeo: from the Latin labeo, meaning 'one with lips'.

Distribution

Edit

Widepread in eastern Asia between the Yangtze and Amur river basins, including China, Taiwan, Korea, Mongolia, Russia, and Japan. May have been introduced to the Mekong basin in Laos.

Type locality is 'Transbaikalia, Dauria; Onon River, Russia [Upper Amur River]'.

Predominantly a riverine fish preferring clear, well-oxygenated, running waters with substrates of sand, gravel, rock or mud, where adults tend to form schools just above the substrate.

At least some populations undergo annual spawning migrations.

Wild individuals are known to feed on benthic crustaceans, insects, molluscs, and other macroinvertebrates.

Sexual dimorphism

Write a noteEdit

Sexually mature, nuptial males develop fine tubercules on the head and fins.

Notes

Edit

This species can be distinguished from other members of the genus by the following combination of characters: absence of dark spots on body in adults; body elongate with slightly convex dorsal profile; head longer than body is deep; snout much longer than postorbital head length; lips well developed, lateral lobes of lower lip broad and thick with folds, median process small; barbel thickness shorter or equal to eye diameter; dorsal spine strong, ⅔ of HL; dorsal-fin origin closer to tip of snout than caudal-fin base base; 15+ gill rakers; 6½ branched anal-fin rays; posterior simple dorsal-fin rays ossified and spinous.
