Abstract

This study searched the prints, the number of nest, eggs and progenies of the mature female sea turtles, nesting on the Kazanli beach. The factors affecting the number of progenies and breeding success also studied. In addition, the morphometric measurements of the ovulated sea turtles were recorded. For this purpose full time expeditions to Kazanli beach were conducted between 15th of May and 16th of October 2004.
Mature female sea turtles arrived Kazanli beach between 19th of May and 11th of August during 2004 breeding season. The highest number of arrivals and nesting was recorded in June and July. The total number of arrivals to Kazanli beach was counted as 1310 during 2004 breeding season. Of the 1310 arrivals, only 410 were resulted with nest, the rest (900), studied just as prints. It was also observed that 7 out of 410 nests belonged to Caretta caretta, 403 nests belonged to Chelonia mydas. The main factors affecting the breeding success were identified as; dog predation, beach erosion, greenhouses built next to the beach, inappropriate surveillance of the beach during the breeding season, concrete blocks and rubbles, and solid waste and rubbish on the beach. Furthermore, the effects of agricultural, industrial and city originated pollution on the breeding success of the sea turtles on Kazanli Beach have not been determined in detail yet.
