Global Importance:	fisheries: commercial; aquaculture: commercial
Resilience:	Medium, minimum population doubling time 1.4 - 4.4 years (K=0.10-0.21; tm=2-3; tmax=12)
Distribution:	Europe: excluding Spain, Italy, Greece and Ireland. Reported from Estonia (Ref. 33247). Regarded as a valuable species both for angling and commercial food in European freshwater fisheries but tends to be a nuisance in areas where it has become established. Subspecies: Rutilus rutilus caspicus of the Caspian Sea; Rutilus rutilus heckeli; Rutilus rutilus fluviatilis (Ref. 683); Rutilus rutilus aralensis (Ref. 11145, 13403, 39702); Rutilus rutilus schelkovnikovi Derzhavin, 1926 of the Aras River basin; Rutilus rutilus uzboicus Berg, 1932 of the Uzboi Valley in Turkmenistan (Ref. 39702). At least one country reports adverse ecological impact after introduction.
Diagnosis:	Dorsal spines (total): 3-3; Dorsal soft rays (total): 9-12; Anal spines: 3-3; Anal soft rays: 9-13; Vertebrae: 39-41. Caudal fin with 18-19 rays (Ref. 2196).
Biology:	Adults inhabit slow-flowing or still, muddy waters (Ref. 9696, 44894). Abundant in rivers, lakes, canals and reservoirs; brackish water populations in the Baltic and the Black Sea are anadromous (Ref. 556, 44894). Can thrive in poor quality, even polluted water (Ref. 9988). Omnivorous, feed on insects, crustaceans, mollusks, and plants. Adults prefer to feed on plants (Ref. 30578, 44894). Pale yellow eggs are found attached to vegetation and tree roots (Ref. 41678). Larvae are demersal. There is only little commercial fishing for this species, but valued for recreational fishing. Utilized fresh and dried or salted; can be pan-fried, broiled and baked (Ref. 9988)
Threatened:	, (Ref. 36508)
Dangerous:	potential pest
