It looks like at least some of the bottlenose dolphins inhabiting the Gulf of Evia have a daily routine that includes spending a few hours foraging near one or more fish farms.
They seem to have become acquainted to human presence, noise, air pollution and dirty water. Apparently, they just care about fish: the wild fish attracted by pellets and nutrients that can be found around the cages.
The dolphins are not afraid of the tangled web of ropes, buoys and cages. They seem to be at home in there, and they engage in occasional socialising.
