Abstract
Purpose. Study of seasonal distribution, migration and behaviour of three dolphin species: common por-poise (Phocoena phocoena relicta Abel, 1905), common dolphin (Delphinus delphis ponticus Barabasch, 1935) and bottle-nosed dolphin (Tursiops truncatus ponticus Barabasch, 1940) in the Zmiinyi Island coastal waters. Methods. Standard methods of dolphins visual observation. Results. Analysis of long-term observations of dolphins have been performed based on the collected data. Dynamics of registration of separate dolphin species depending on season of year has been shown. Conclusions. It has been established that common porpoise was seen near the island the most often (74.5% of all the dolphins registered). The registered common dolphins and bottle-nosed dolphins were significantly less in number – 17.5 and 8.0% respectively.
