Lošinj field base

The research project in the Cres-Lošinj archipelago began in 1987. It is the longest systematic study of bottlenose dolphins (Tursiops truncatus) in the Mediterranean. Research stretches along the eastern coast of the island of Lošinj, which has many beautiful bays and smaller islands such as Trstenik, Ćutin, Palacol, and Orjule, some of which are characterized by an exceptionally rich marine flora and fauna.

Numerous years of study of the bottlenose dolphin population in the waters of Losinj, has contributed to creating a comprehensive picture of the ecological state of these endangered marine mammals. The main research methods include techniques such as photoidentification - photography and identification of individuals on the basis of visible scars and incisions that are present on the dorsal fins of the dolphins. Analysis of the data indicates the number of population is currently estimated at about 100 individuals.

Due to the continuous increase in the number of human activities that occur at sea, special attention is being paid to human impact on this species. In 2004 we began to monitor the noise in the region using a hydrophone. This monitoring was applied to access the impact noise has on the habitat use of dolphins as well as with monitoring the behavior of individuals and their reactions to the immediate vicinity to boats.

In addition Blue World also conducts research into the diet of the bottlenose dolphins and the analysis of heavy metals present in the tissues of dead animals. A recently initiated genetic study and study on biomarkers in the future will certainly bring additional information on health status Lošinj bottlenose dolphins.

The aim of this project is to monitor the status of this subpopulations of bottlenose dolphins through continuous research to achieve its care and contribute to the preservation of biodiversity of the Adriatic Sea. In the last few years the project has expanded its operations and research area which now includes part of Virskog Sea, the western coast of the island of Lošinj and Kvarner and part of the Velebit Channel.
