Abstract

This study was performed in the southern part of Çandarlı Bay between May 2015 and May 2018. The aim of the research was to determine the existing cetacean species and their distribution. Cetacean monitoring surveys were conducted biannually for three years, and the presence of bottlenose dolphin Tursiops truncatus and common dolphin Delphinus delphis were detected by visual observations. Total encounter rate of delphinids in the study was 1.7567 sightings per 100 km. The main reason for such a low encounter rate is considered as that the study area is in an industrial zone.

Keywords: Cetacean, monitoring, encounter rate, bottlenose dolphin, common dolphin
