Analysis of the Lower Dniеster and the Dniеster Liman ichthyofauna structural characteristics has been carried out under conditions of regulated discharge, increasing pollution and spawning grounds degradation. Decrease in fish species composition has been shown, as well as the disappearance of some native reophilic and lithophilous fish species as the result of the Dniеster River discharge regulation. Data about rare species found in the Dniеster River and the Dniеster Liman are presented, including Benthophiloides brauneri Beling et Iljin, 1927, which has not been recorded in the Lower Dniеster before. The dwindling of catches of the main commercial fish species is also shown.enIchthyofauna, Lower Dniеster, species composition, structure of catches, enviroGRIDSArticle
