Abstract—This article provides information on the modern distribution of an alien species in the ichthyofauna of the Republic of Dagestan, the topmouth gudgeon Pseudorasbora parva (Temminck et Schlegel, 1846) (Cyprinidae). This species is found practically in all studied water bodies—the Manasozen, Gamriozen, Ulluchai, Rubas, and Avarskoe Koisu (a tributary of the Sulak River, in the area of the Gotsatlinskaya HPP) rivers—and in Lake Mochokh. Apparently, the wide distribution of P. parva is associated with its ecological plasticity, migratory activity, high growth rate, accelerated puberty, and high level of survival of the offspring.
