The article deals with the quantitative development of shellfish waters in the basin of the upper, middle and lower reaches of the Chulym River. There are the data on the quantitative development of macrozoobenthos and shellfish in different types of reservoirs rivers, floodplain lakes and paranasal reservoirs. The reservoirs basin of the upper reaches of the river Chulym are the most depleted by quantitative development as macrozoobenthos and shellfish. Quantitative indicators of macrozoobenthos and shellfish increase in the middle reaches of the river basin of the Chulym River. The richest quantitative development of macrozoobenthos and shellfish waters is lower reaches of the water basin of the Chulym. Different types of reservoirs in the river basin of the Chulym River are characterized by different quantitative indices of macrozoobenthos and shellfish. The lowest number of macrozoobenthos and shellfish are featured in river waters. In the paranasal waters of rivers there is an increase of quantitative development of macrozoobenthos and shellfish. Maximum quantitative development of macrozoobenthos and shellfish is identified in floodplain lakes of the river basin of the Chulym.
