Editing Common dace (section)

==Distribution==
The common dace is native to Europe and northern Asia where its occurs in the basins of the [[North Sea]], [[Baltic Sea]], [[White Sea]] and [[Barents Sea]]. It also occurs in the basin of the [[Caspian Sea]] in the drainage systems of the [[Volga River|Volga]] and [[Ural River]]s and in the [[Black Sea]] basin it is found in the [[Danube]] and the [[Dnieper]]. In France it occurs in the [[Seine River]] drainage and in the drainages of the [[Rhone]] and [[Arc (Provence)|Arc]] which flow into the Mediterranean. In the Danube main river of Romania as well as in Scandinavia north of 69°N and most of central Finland this species has a localised distribution. The populations from Siberia and East Asia are normally assigned to ''[[Leuciscus baicalensis]]'' and ''[[Leuciscus dzungaricus]]''.

This species has been widely introduced in areas of Europe where it did not previously occur. For example, it has become established in [[Ireland]] since the early 1900s, having been taken there as a bait fish to catch larger fish such as pike.<ref name = Fishbase/> Following its introduction in Ireland, it has benefited from [[Enemy release hypothesis|parasite release]], meaning that with its introduction it has lost its normal set of parasites and might thus have a competitive advantage over native species.<ref name="Tierney 2020">{{cite journal |last1=Tierney |first1=P.A. |last2=Caffrey |first2=J.M. |last3=Matthews |first3=S.M. |last4=Costantini |first4=E. |last5=Holland |first5=C.V. |title=Evidence for enemy release in invasive common dace ''Leuciscus leuciscus'' in Ireland: a helminth community survey and systematic review |journal=Journal of Helminthology |date=2020 |volume=94 |pages=e191 |doi=10.1017/S0022149X20000759|pmid=32924909 |doi-access=free }}</ref>
