Summary: 

A ten year study in the Aegean Sea, divided into two sub-periods (1995-2000; 2003-2006) examined bottom trawl fishery data for chondrichthyan fishes. A total of 30 different species were caught making up 14.3% of the total catch in weight and 2.2% by number. A significant decrease in the chondrichthan species richness  and abundance was observed. More than 90% (by number) of individuals were discarded at sea.
