Abstract

Cetacean sighting data were collected on a research cruise carried out in
autumn season

(27.10-02.11.2007) in the western Black Sea between Istanbul (Turkey) and
Constanta (Romania)

and vice versa. This research cruise was conducted with a 32-m research
vessel R/V YUNUS-S in

the international waters. Average speed of the vessel was 10 nautical
miles/h. At each sighting of

cetaceans, species, numbers of animals, location (coordinates), time,
behaviour of animals were recorded.

During the survey, totally 417 nm was covered and 33 h of effort was made.
The aim of the

preliminary study was understanding the size and distribution of dolphin
population in the western

Black Sea. During the study, totally 16 sightings (91 individuals) of three
species; common dolphin

(Delphinus delphis), bottlenose dolphin (Tursiops truncatus) and harbour
porpoise (Phocoena

phocoena) were recorded. Number of individuals and number of sightings are
61 common dolphins

in eight, 29 bottlenose dolphin in seven, and a harbour porpoise in one
observation. The overall

encounter rate was 3.83 sightings/100nmiles. Common dolphin was the most
often observed species

(50%), followed by the bottlenose dolphin (44%), and harbour porpoise (6%).
