A revised checklist of the fish fauna of the Black Sea is reported. This paper is the first attempt to present an actual Check List of the fishes in the Black Sea according to the data available in the Black Sea countries, as well as their current conservation status, enlisted in IUCN. The total number of the Black Sea fish species is 189. Concerning the conservation status only two species (1.06 %) are extinct (Acipenser nudiventris and A. sturio), 3.70 % are critically endangered, 16.40 % are vulnerable, 1.06% are endangered, for 10.58 % there is a lack of data, 26.46% has been classified in the category “Least concern”, 2.65 % are “Near threatened” and 38. 10% are “Not evaluated”.

A rare live record of the loggerhead sea turtle Caretta caretta (Linnaeus, 1758) is reported from the Dzharylgach Gulf in the north-western Black Sea. This is the first record from Ukrainian waters since 1962 and the northernmost record of the species in the Black Sea. The loggerhead sea turtles of the east Mediterranean origin are increasingly often seen in the Marmara and the Black Sea during the latest decade, which is an evidence for potential expansion of this species range, at least partly due to climate changes. Key words: sea turtles, Caretta caretta, Black Sea, Ukraine, range expansion.

Data on the state of bottom vegetation and biotopes of marine protected areas (MPA), which are part of six specially protected natural areas (SPAs) of Sevastopol, are presented. Based on a synthesis of hydrobotanical studies for 2008-2018, the composition and structure of Cystoseira and Phyllophora phytocenoses, key for the coastal zone of the southwestern Crimea and the Black Sea ecosystem, are characterized; their species diversity, production indices, and distribution features are described. A comparative analysis of long-term changes showed that in the structure of the Cystoseira phytocenosis of MPAs there was an increase in the number of green algae, indicators of household pollution, the lower boundary of the distributions of both phytocenoses was halved. For the first time for the Sevastopol region, data are presented on the area of Cystoseira and Phyllophora biotopes, which amounted to 3323.5 and 430.5 ha, respectively (9 and 17.3% in the areas of protected areas). Scientifically based recommendations for the conservation and restoration of phytocenoses and biotopes of key species with high conservation status are proposed.
