Abstract—The species composition of plankton invertebrates was studied in the middle Vychegda River (the
main tributary of the Northern Dvina River) in 2003–2005. A list of planktonic rotifers and lower crustaceans
was made. The dominating complexes of zooplankton organisms were found. The quantitative characteristics
of plankton communities in the river were described.

Key words: zooplankton, dominating complexes, seasonal dynamics, river Vychegda.
