Comments: Found in central and northern Italy (Ref. 26100). Present everywhere and abundant in several localities on the middle courses of rivers. Has entered small streams and rivulets and seems to be a direct competitor with Leuciscus lucomonis and Rutilus rubilio. Stocked unintentionally. Recorded from the Ombrone, Albegna and Fiora rivers. An invasive species (Ref. 45688). Almost extirpated in River Soca due to invasion of a competitor Chondrostoma nasus (Ref. 59043). Introduced to Tuscany and Latium in Centa, Magra, Arno, Ombrone and Tevere basins (Ref. 59043). Also Ref. 94493. Status of threat: Endangered (Ref. 119201).

Short description Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία

The only species in genus which differs from species of Chondrostoma in Apennine Peninsula by having broad dark midlateral stripe from head to caudal base, arched mouth, lower lip with thin but well developed cornified sheath, 50-62 scales along lateral line; 8½ branched dorsal rays, 14-19 gill rakers, slender body, depth 20-27% SL, and pectoral, pelvic, anal and caudal fins at least with red basis (Ref. 59043).

Found in middle reaches of rivers and main tributaries, in piedmont, with moderate to swift current, over gravel bottom. Occurs in groups. Omnivorous, feeding mainly on aquatic insects and epilithic algae. Undertakes small spawning migration in large groups towards main tributaries. Spawns in swift current on gravel (Ref. 59043). Reported to spawn in March-May (Ref. 26100) and in May-June (Ref. 59043). Threatened due to the introduction of other species and habitat destruction (Ref. 26100).
