The Ichthyofauna of Separate Reservoirs of the Republic of Armenia and the Factors Affecting its Formation

Öz

10 fish species belonging to Cypriniformes order have been found in Tavush, Joghaz and Aygedzor reservoirs located in the North of Armenia. The Ichtyofauna of all three reservoirs are quite different (the Jaccard similarity index was from 0.11 to 0.43), which witnesses that the fish communities of each of the reservoirs have been formed independently and spatially, depending on the influence of factors such as irregular and uncontrolled acclimatization, disruption of fish migration due to hydraulic structures, drastic changes in a number of hydrogeological indicators in the freshwaters, poaching, etc. As a result, the Ichthyofauna of the studied reservoirs has undergone drastic changes and mainly consists of low-cost waste fish․
