Coregonids are the species in the structure of the fish fauna of the Ob-Irtysh basin that remains the least resistant to the anthropogenic change of environment. The gill apparatus is one of the indicator organs as its state allows us to make conclusions as for the general morphofunctional state of the species. The state of the gills in whitefish in the Northern Sos´va River during the summer feeding period was evaluated using the histological method of analysis. All the observed fish species had some pathological alterations in their gills. The manifestation rate of such alterations decreases in the following range: peled, Siberian Coregonid fish, tugun. Hyperplasia of the gill epithelium is the dominating pathology type. Tugun rarely leaves the basin of the Northern Sos´va so it has the least rate of gills deviations, because conditions of that river are more favorable in comparison with the Ob River or with the Gulf of Ob. A significant number of pathological alterations of the gills of whitefish confirms that the character of the aquatic environment was moderately stressful and seems to be caused by the unfavorable hydrochemical regime of the river in the summer of 2012.
