Researches in the reserve Bastak (Jewish Autonomous Region) were conducted in 2007-2016. Fish fauna of different biotopes of the reserve differ both on specific structure, and by quantity of taxons. In the main territory of the reserve water biotopes of mountain upper courses of the rivers, rivers of foothill type, the small flat rivers, big inundated lakes and small lakes characteristic of a flat part of the reserve are widespread. The specific structure of fish fauna of reservoirs of the main territory of the reserve includes 35 species of fish, representatives of 28 genus’s, 14 families, 9 groups today. Taxons of fishes of palaearctic origin prevail (from groups Cypriniformes, Siluriformes, Scorpaeniformes, etc.) – 22 species, 19 genus’s. Fishes sino-Indian by origin (from groups Cypriniformes, Siluriformes, Perciformes) – 12 species, 11 genus’s are to a lesser extent presented. In a fish fauna of the reserve six groups of the fishes different in zoogeographical origin are presented. According to the scheme of faunistic complexes offered by G.V. Nikolsky representatives of ikhtiokompleks live in the reserve: tertiary flat, boreal flat, boreal foothill, Indo-African, freshwater Arctic, Chinese flat [1]. In the systematic relation the autochthonic Chinese fish fauna of the Russian site of the Amur basin is rather uniform – all her representatives treat Cypriniformes group, three families: Cyprinidae, Cobitidae, Balitoridae. Ecological parameters of the habitat are wide, in group evribionta are presented generally, there are also reophile types – Cultrinae, etc., to a lesser extent - limnophile fishes. Fishes of the autochthonic Chinese fish fauna are moderately thermophilic, a river basin Amur – natural northern border of their area. In the reserve Bastak during the researches seven species of fish – representatives of Chinese flat fish fauna are revealed: Hemiculter leucisculus (Basilewcky, 1855), Xenocypris macrolepis (Bleeker, 1871), Opsariichthys bidens (Gunther, 1873), Pseudorasbora parva (Temminck et Schlegel, 1846), Hemibarbus maculatus (Bleeker, 1871), Hemibarbus labeo (Pallas, 1776), Lefua pleskei (Herzenstein, 1887). Five of seven listed types (Hemiculter leucisculus, Xenocypris macrolepis, Opsariichthys bidens, Hemibarbus labeo, Lefua pleskei) are found during the expedition of 2012 on average a current of the Yin River, on estimated northern border of an area; two look (Hemibarbus maculatus, Pseudorasbora parva) were noted in the Glinyanka River.
