Burhaz M. Features of formation of ichthyotsenosis of Shabolatsky estuary in the conditions of anthropogenic transformation of the reservoir

In the dissertation the peculiarities of formation of ichthyotsenosis of Shabolatsky estuary are considered depending on: salinity of water, connection with adjacent aquatories, acclimatization and introduction of fish and anthropogenic contamination. The peculiarities of the spatial distribution of the most mass species of fish in the estuary, the size-mass and age structure of the populations and its changes in the indicators resulting from anthropogenic transformation of the reservoir in recent years have been established. A comparative analysis of the status of the forage base of the estuary has been carried out, the peculiarities of feeding of the most massive representatives of the ichthyotsenosis and the changes resulting from the reduction of the forage resource have been characterized.
