Material examined. Table 1; Fig. 6C.

Presence of two dorsal fins without spines, first and second dorsal fin with six to eight unbranched rays, and second dorsal fin with eight to 12 branched rays. This is an invasive species, first found in 1979 ( Potapov et al. 1998). It was recorded in small rivers (to 101 km from the source) and all other types of waterbodies, except for storage reservoirs. Its highest occurrence rate was observed in oxbows as well as karst and suffusion lakes (75–87.6%). Its occurrence rate in ponds is moderate (28.6%), and in rivers, low (10.3%; rivers to 25 km from their source); or very low (1.9%; rivers at 26–100 km from their source). The highest abundance was observed in landlocked oxbows, where its average share in catches is 30.9%.
