Decline of common dolphins in western Greece

This graph shows the decline of common dolphins around Kalamos in years 1995-2007, based on photographic mark-recapture.

Common dolphin numbers dropped from about 150 animals in 1996 to only 15 in 2007.

Ongoing research by Tethys indicates a high risk of local eradication for common dolphins by the year 2010 unless fishery management measures are implemented immediately within this area.
