Abstract
The results of the study of common minnow populations in the Ungra River (conservation zone) and the Chulman River (Neryungri town) in Southern Yakutia were presented. The main biological characteristics of the fish were given. Minnows proved to be highly adaptive: their lifespan could exceed 10 years in the technogenic zone of the Chulman River in the absence of predators and competition for food. Common minnow was a host to 36 species of parasites, 11 of them were typical for this fish, and 9 species were detected for the first time in Yakutia.
