T he Ichtyofauna of all three reservoirs are quite different  ( the  Jaccard similarity index  was from  0.11 to 0.43 ) , which witnesses that  t he 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 ․
