Abstract

This research was conducted to record the fish species inhabiting Lower Dniester River in frames of the Moldovan borders and its drainage between 2011 and 2022. Following the investigations the list of recorded fishes from the study area totaled a number of 78 species, belonging to 18 families, 13 orders and 2 classes. Changes in the composition of fish of the Lower Dniester over a long period are considered. The factors determining the state of the fish fauna are change in the hydrological regime associated with climate change and hydro construction, damming of the riverbed, point and non-point river pollution, developed poaching, and poor cooperation between riparian countries in the joint regulation and use of fish and other biological resources. Measures are proposed for the conservation and restoration of the diversity of the autochthonous fish fauna.
