Abstract

A local population of bottlenose dolphins (Tursiops truncatus) in Slovenian and adjacent waters (northern Adriatic Sea) was studied between 2002 and 2008. Boat-based surveys, land-based surveys and standard photo-identification procedures were carried out. A total of 120 sightings were recorded and 101 well-marked dolphins photo-identified. Resighting rates within and between years showed a relatively high rate of site fidelity for some individuals. The group size ranged from 1 to 43. Offspring were present in 53.3% of the groups. Annual mark-recapture density estimates of 0.069 dolphins/km 2 seem to be good baseline information for conservation management.
