The research results on the heavy metals and arsenic content in the water and bottom sediments of freshwater bodies of the Republic of Adygea, Krasnodar Krai, Stavropol Krai, and Rostov Region are given for the period of 2016–2018. The levels of pollution of the habitat of aquatic biological resources have been estimated in accordance with the standards for freshwater bodies of fisheries importance and the average long-term values. Average heavy metals and arsenic concentrations in the water bodies are compared. The averaged results are presented for the organs and tissues of such commercial fish species as the pike perch (zander) Sander lucioperca, crucian carp Carassius, white bream Blicca bjoerkna, European perch Perca fluviatilis, common bream Abramis brama and the roach Rutilus heckelii caught in the Krasnodar, Takhtamukaysk, Otkaznensk, Novotroitsk, Chograysk, Kryukovsk, Varnavinsk, Veselovsk, Proletarsk and Ust-Manych Reservoirs, the Don River, the Kuban and Mokraya (Wet) Buyvola Rivers. The levels of heavy metals and arsenic accumulated in the muscles and gonads of the fish have been compared in accordance with the Russian Sanitary Rules and Norms for Food Quality (SanPiN2.3.2.1078–01). Heavy metals and arsenic concentrations have been assessed in the same species caught in different bodies of water and in different species caught in the same body of water. The determination of heavy metals and arsenic in the fish and the water bodies under study was carried out in accordance with the procedures developed in the Azov-Black Sea Branch of “VNIRO” (“AzNIIRKH”)
