INVASION OF THE THREE-LIPS (OPSARIICHTHYS UNCIROSTRIS) IN THE RESERVOIRS OF THE TURKESTAN REGION

Based on the materials of long–term research, data reflecting the current state of an alien species – three-lips (Opsariichthys uncirostris (Temminck et Schlegel, 1846)) in the waters of reservoirs of republican and local significance of the Turkestan region are presented. The article discusses the reasons for the appearance of this species in the study area, biology and degree of distribution. The current biological state, biological parameters (length, weight,age, fatness according to Clark and Fultan,) of the caught individuals for 2022-2024 are presented. as well as the scheme of the capture stations of this type in the waters of the river Syrdarya is located within the Turkestan region. A photographic material of three-lip individuals caught on the Syrdarya River in 2023 at the fishing site No. 1 is presented. A preliminary assessment of the potential impact of an alien species on the ichthyofauna of the reservoirs of the basin is given.
