Note
Between July 1996 and October 2001, 190 boat-based photo-identification surveys were carried out on the population of bottlenose dolphins (Tursiops truncatus) in Florida's Indian River Lagoon. Survey effort varied geographically across and within study years, but was relatively high and consistent (number of surveys = 158. 83%) between 1998 and 2001 in the primary study area (PSA) between Sebastian Inlet in the north to Fort Pierce Inlet in the south. A total of 336 dolphins were photographically identified, with 149 of these individuals found in the PSA.
