Ecological state of Tudakul reservoir in Uzbekistan and estimation of fish capture in last decades

The problem of anthropogenic impact of the Tudakul reservoir has not been spared. In the first years of the reservoir’s existence, its ichthyofauna was formed by the fish of the Zarafshan River, which were represented by both rheophiles and limnophiles, and initially it consisted of 11 aboriginal species and introduced fish. This paper gives a brief physical-geographical, hydrological, hydrochemical, hydrobiological characteristics of the Tudakul reservoir. An assessment of the ecological state of the reservoir, ichthyofauna and fish catch in it over the past decade is given. Recommendations for the rational use of the Tudakul reservoir are given.
