title: FEATURES OF THE HYDROBIOLOGICAL REGIME AND STRUCTURE OF ICHTHY-OFAUNA LAKES KARTAL AND KAGUL IN THE CONDITIONS OF FISHERIES USE OF RESERVOIRS
abstract: The results of hydrobiological monitoring of Danube lakes (Kagul and Kartal) are given. These lakes are currently used as reservoirs for growing commercial fish. For the study of phytoplankton, zooplankton, macrozoobentos and ichthyofauna, the material was collected in March, July and October 2019.
