Abstract

The Turkish coastal regions where the edge of the seaward continental shelf lies at around the 200 m depth contour constituting a small portion of the sea that over 90 percent of the catch are taken. In these coastal regions several major distinct biogeographical regions can be identified such as the Black Sea, the Sea of Marmara, the Aegean and the Mediterranean coastal regions. This is the result of a combination of factors including primarily the influence of the warm, saline waters of the Mediterranean Sea and the relatively cool, less saline rich nutrient water of the Black Sea. The Turkish Black Sea coastal region has generally narrow continental shelf with a large fresh water input increase the productivity of the area where 80 percent of the coastal shelf annual catch are taken compare with the Mediterranean Sea where the continental shelf and fresh water input are narrow and small respectively where the catch represent about only 4 percent of the total annual catch. The Sea of Marmara coastal region is a mixing area between these two different seas and represent about 12 percent of the total annual catch. The increasing demand on living resources is growing recognition of the potential of mariculture with a certain limitations in the coastal regions of Turkey. This paper attempts to collect existing data to prepare a country report on this subject.
