The Abrau Peninsula is the northernmost part of the Caucasian subtropical zone by the Black Sea. Its coastal zone with unique landscapes and habitats are Nature Reserves under protection of the State. Little is known about marine fauna inhabiting the sea off the peninsula, particularly in the reserved areas. To learn more, the inventory of species richness of the fish and decapods was made and the modern taxonomic structure in the area was explored. The expeditions launched in May and in September 2016 studied the taxocenes of fish and decapods in the coastal seawater of Utrish State Nature Reserve. Traditional methods (ichthyoplankton samples, hand sampling), photography and video recording were used. In the revision of species richness scientific literature and the recent original evidence were used. The taxocene of fishes included 64 species, 46 genera, 36 families, 14 orders; the taxocene of decapods – 14 species, 13 genera, 12 families, 1 order (Decapoda). Naturalization of 3 alien mediterranean species was confirmed.
