Annotation The article presents some information about phytophilous zooplankton of Lake Kenon, its role in the process of water self-purification and fish nutrition. Lake Kenon is located within the city of Chita, there is a thermal power plant (TPP) on its shore. In the sharply continental climate of Transbaikalia, the discharged water of the TPP influences the species composition and trophic structure of zooplankton. While analyzing phytophilic zooplankton, we destinguish 11 trophic groups of zooplankton and determine the dominant zooplankton complexes in the thickets of higher aquatic vegetation. Zooplankton participates in the processes of the lake self-purification through nutrition and sedimentation. The activity of plankton organisms results in the decrease of the quantity of suspended solids, which contain the following food components – phytoplankton, bacterioplankton, zooplankton and detritus. The intensity of the self-purification process in the overgrown littoral is twice larger than in the non-overgrown part of Lake Kenon. The zooplankton of submerged aquatic vegetation plays the greatest role in the purification of water. The zooplankton production is calculated in the overgrown and non-overgrown parts of the lake. The largest number of products is created by the zooplankton communities in vegetation areas – 81,4 %. The highest values of zooplankton production, which can be used by fish, are characteristic for thickets of heated areas of bur-reeds (49,5 kJ/m³), pickpockets and limnanths (41,7 kJ/m³).
Key words Lake Kenon, cooling reservoir, phytophilic zooplankton, trophic groups, self-purification, products
