Common dolphins were once abundant throughout the Mediterranean Sea. Today they are declining rapidly, surviving only in portions of their former range. In western Greece, the sea around the island of Kalamos is their last stronghold, or at least it used to be. So why are the dolphins disappearing?
We interview Giovanni Bearzi, the President of the Tethys Research Institute in Italy, and a Pew Fellow in Marine Conservation. Giovanni has been studying coastal dolphins in the Eastern Mediterranean Sea for two decades. What began as a study on the ecology and behavior of common dolphins around Kalamos, became a systematic record of their demise.
Only 30 kilometers away from Kalamos is the Amvrakikos Gulf where coastal bottlenose dolphins are thriving. Why is there such a drastic difference in the health of these two dolphin populations?
We meet two local fishermen and discuss their relationship with dolphins and the state of sea around their community. Could what is happening to the common dolphins of Kalamos, also explain why they are disappearing throughout the Mediterranean Sea?
