Abstract
The resalts of long-term studies of reproduction of snail population Opisthorchophorus troscheli (Paasch, 1942) in outfall of Kargat river (from Chany Lake Basin) was brought. The article include data about morphology of Bithyniidae snails laying. Data about period and duration of reproduction of O. troscheli in different years with temperature regime of pond was presented. The quantitative characteristics of Bithyniidae reproduction in natural conditions on south of the Western Siberia was provided. The findings was completed the results of laboratory research. The quantity of egg clusters in laying came down to finish of reproduction. The duration of embryonic development in O. troscheli was studied at different temperature conditions. Ecological aspects of reproduction Bithyniidae snails for the Western Siberia was investigated for the first time in Siberia.
