The present study provides information on the stranding of cetaceans along the
Bulgarian Black Sea Coast during 2017. Observations were made trough covering transects
along the Bulgarian Black Sea Coast. A total of 198 cetaceans of three species were found -
Harbor Porpoise (Phocoena phocoena), Bottlenose Dolphin (Tursiops truncatus), and
Common Dolphin (Delphinus delphis). The most numerous were the harbor porpoise - 48%
followed by the bottlenose dolphin - 15% and common dolphin - 8%. The most significant
number of strandings was observed during July and August (54% of all cases). Cetacean
strandings events were relatively highly concentrated in the area of Shabla, Varna and
Pomorie
