ABSTRACT. We conducted an initial study of the microcrustacean species diversity of Chukchagir Lake and its basin (Khabarovsk Territory, Far East of Russia). In total, 29 Cladocera taxa and 14 Copepoda taxa were found. Two of these species, Disparalona ikarus Kotov et Sinev, 2011 and Thermocyclops asiaticus (Kiefer, 1932) are endemic to the Far East. In the investigated region, the cladocerans were more species-rich than the copepods. The species richness of Chukchagir Lake fauna was lower than that of Bolon Lake. This fact is probably explained by the anoxic bottom layer of Chukchagir Lake.

KEY WORDS: Crustacea, Cladocera, Copepoda, fauna, biodiversity.
