Marine Ecological Journal| Резюме: | Stomach content has been studied in 157 stranded and by-caught Black Sea cetaceans including 123 harbour porpoises (Phocoena phocoena relicta), 26 common dolphins (Delphinus delphis ponticus) and 8 bottlenose dolphins (Tursiops truncatus ponticus) collected in Ukraine, Bulgaria, Georgia and Russia. Some new prey species were recorded including the haarder (Liza haematocheila) and pickarel (Spicara flexuosa) for harbour porpoises, and the garfish (Belone belone euxini) for common and bottlenose dolphins. Currently, basic food species of harbour porpoises in Ukrainian waters are represented by the sprat (Sprattus sprattus phalericus), whiting (Merlangius merlangus euxinus) and anchovy (Engraulis encrasicolus). The updated list of Black Sea cetaceans prey includes at least 30 fish species from 21 families; a total of 20 fish species are known to be consumed by harbour porpoises, 11 – by common dolphins and 14 – by bottlenose dolphins. |
