Photo-identification is a non-invasive technique used by scientists around the world to study dolphins populations around the world. The theory at the basis of photo-identification is that the majority of the dolphins within a population can be unequivocally distinguished thanks to unique nicks and marks on the dorsal fins.
The term “capture” is used to identify the first time that a good quality photograph of the dorsal fin of a specific individual was taken and added to the photo-identification catalogue. The following encounters with the same individual are called “recapture”.
The combination of capture and recaptures occasions forms the
“history file” of a specific individual or a population. This file represents the basic data needed to investigate distribution, social structure, abundance, population trend and to identify key habitats of dolphins in the region.
Your sightings and photographs will be included in an existing
catalogue and will be analysed together with data collected during dedicated boat based survey to provide seasonally updated
The humpback dolphins number 132 is a female and has been sighted every year from 2006 to 2012
