Abstract

Data collected by 11 scientific bottom trawling operations from three different depth layers (≤50 m, 51-100 m, 101-200 m) in 2009 and 2010 on the Didim (southern Aegean Sea, Aydın) coast were used to describe the distribution and abundance of Chondrichthyes species. A total of 15 species were recorded. At present, insufficient data prevent us from quantifying the impact of this fishery on these species, but our findings highlighted the importance of researches to assess the abundance and geographic extent of these populations.
