| Tartalmi kivonat: | The existence of aquatic populations of any region is determined by the amount and quality of water accessing the area. The quality of water in the river is dependent on interactions between a number of processes either natural or caused by anthropogenic agents. The former conventionally refers to the eduction (the so-called 'self-purification' processes) of water. Numerous living organisms participate in these processes by withdrawing organic matter and accessible mineral substances from the water. On the other hand, more often, certain hydrobionts are associated with the pollution of water with extraneous products related to the various economic activities of humans. The more stable a community of aquatic dwellers is, the more successful they will be in withdrawing and transforming various extraneous admixtures present in the water. As a result, better water quality will be achieved. The knowledge about the structure and the peculiarities of the functioning of the communities of aquatic organisms is a necessary condition for the effective control of water quality and for the due detection of unfavourable changes. Knowledge in this field serves as basis for developing practical measures of the improvement of water quality. Under the mountainous conditions of the Carpathian territory of Ukraine, a relatively big river (i.e. River Tisa: a large tributary of River Danube) serves as the basic drain of the area. River Tisa is the major aqueous artery and the basic source of drinking water in Hungary. In accordance with those mentioned above, we consider that finding out the species composition of communities inhabiting the basins of the River Tisa region is an important stage of the research analysing the formation of water quality. |
