15/08/2015 – Risso’s dolphin photo-identification catalogue
Associació Cetàcea presents the online Risso’s dolphin (Grampus griseus) photo-identification catalogue as a result of the sighting surveys carried out within the Photo-Identification Project: Whales and dolphins along the Catalan coast during the year 2014. The catalogue is intended to be a good tool to improve our knowledge about the Risso’s dolphins visiting the central Catalan coast.
1452 photographs were taken during the two Risso’s dolphin sightings of 2014. Of these, 949 photographs containing dorsal fins of different individuals were selected. Using a selection process based on 7 technical criteria, the volunteers of Cetàcea selected 132 photographs with enough quality to be included in the catalogue.
Thanks to the great task of the volunteers that collaborated in this project, 31 individuals have been catalogued after the 2 sightings of 2014. But we hope that the catalogue will keep growing in the future.
