Where is the quagga mussel from?
Dreissena rostriformis bugensis is indigenous to the Dneiper River drainage of Ukraine. It was discovered in the Bug River in 1890 by Andrusov, who named the species in 1897 (Mills et al., 1996). Canals built in Europe have allowed range expansion of this species, and it now occurs in almost all Dneiper reservoirs in the eastern and southern regions of Ukraine and deltas of the Dnieper River tributaries (Mills et al.,1996).
