Material examined. Table 1.

Presence of 15–16 branched caudal-fin rays and by the cylindrical body shape. It has been recorded in rivers of all types and river ponds. This is the most abundant species in shallow rivers, which inhabit the springhead of many rivers, frequently being the only representative of species of the fishes in such channel rivers. Accord- ing to river enlargement, its occurrence rate and share in catches decrease, stabilizing at levels of 15.4–16.7 and 1.2–2.2%, respectively, 100 km from the river source. The stone loach abundance in ponds was low (0.4%), as well as its occurrence rate (3.6%).
