THE IMPACT OF THE ANTHROPIC FACTORS ON DISRUPTING AND DESTABILIZING THE ECOLOGICAL BALANCE OF THE VÂLSAN RIVER
Journal Title: Current Trends in Natural Sciences - Year 2013, Vol 2, Issue 4
Abstract
The Vâlsan river is the only ecosystem in Romania and in the world where Romanichthys valsanicola, a Tertiary era relict, lives; this fish has a strictly limited habitat range and is on the Red List of U.I.C.N – under resolution D-46 of the E.C., as a “critically endangered species”. At present, the river Vâlsan is subjected to a cumulative effect of the disrupting factors upstream, as a result of the hydroelectrical structures and of human activity. It also suffers a number of negative effects relating to the quantity and the quality of its water, which require taking urgent steps in order to be diminished. The present paper presents the comparative situation of the invertebrate and piscicultural fauna prior to, and after, the beginning of the functioning of the Vâlsan hydrotechnical structure.
