THE HIGHER WATER VEGETATION OF THE LAKES OF THE DIFFERENT LANDSCAPE ZONES OF THE SOUTH OF THE TYUMEN REGION (IN CONNECTION WITH INSERTION OF THE GRASS CARP IN THEM)

The object of investigation: the lakes of the South part of the Tyumen region. The work is aimed at studying the ecological peculiarities of the water vegetation and the possibilities of the rational use of the water reservoir vegetation covering. For the first time, a comparative ecologosystematic analysis of the water vegetation of the south-taiga, subtaiga and forest-steppe lakes has been made. The evaluation of the common growing-over of the water reservoirs and the participation in the process of the lakes growing over with water plants, relating to the different ecological groups, has been given. The productivity of the hydrophytes communities in the lakes with the different ecological conditions has been established. The annual production of the water reservoir vegetation covering has been computed. The purpose of the fishes appearing (grass carp) in the concrete lakes to make biomelioration and to receive the additional fish production has been determined. The results of the investigation have been applied to the development of the technology and normatives by the product growing of the phytivorous fishes in the lakes of the South of the Tyumen region. The data of the detailed hydrobotanic investigations can be used for the information about the variations in the vegetative covering of the water reservoirs with the local and regional monitoring. The field of application: the hydrobotany, the ecology, the lake fish growingAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
