Presence of subequal jaws, and convex border of the anal fin. It was observed in all types of rivers, stream- ing oxbows, and in one pond (Artaev 2015). Its share in catches was the highest (18.1%) in rivers at a distance up to 25 km and decreases to a stable level about 7% downstream to a distance of 500 km. Mainly adult individuals was found in the upper reaches of rivers; the juveniles were not collected. This species is rare and in low abundance in flow-through lakes. Despite atypical in ponds, this species was however collected in one pond site (53.5779° N, 44.0143° E) with share catch about 46.2%.
