Technological influence on the current state of the species composition of the ichthiofauna of the r. Samara in the Novomoskov District of the Dnipropetrovsk Region

The species composition of the ichthyofauna Samara River under influence man-made factors in Novomoskovsk district Dnipropetrovsk region is presented. environmental problem characterized, and on revealed. was analyzed based literature data, field ichthyological studies were also conducted to determine River. results technogenic modern realities have been obtained are summarized relation ichthyofauna. In studied area, it found that there largest population following species: Neogobius fluviatilis Pallas, 1814; Alburnus alburnus Linnaeus, 1758; Carassius auratus gibelio Bloch, 1782; Scardinius erythrophthalmus Perca Rutilus rutilus Lepomis gibbosus Esox lucius 1758. restoration natural water bodies example study model River, Novomoskovskiy district, region, subject context scientifically useful interest. Technogenic a significant impact reservoir formation it. Own research area ​​the factors. A table fish living compiled their status distribution indicated. We compared data with materials previous years. To improve mechanical biological reclamation stocking white carp, crucian carp proposed. Therefore, concluded processes changing ichthyocenosis pollution require necessary optimizing interventions attention researchers monitoring.
