The investigation of sea of biological aspects of sea turtles in Hormoz and Henqam islands

In the present study an attempt was made to investigate some of the biological aspects of sea turtles in Hormoz and Henqam islands. In this regard 73 turtles were chosen for the biometry and their biological specifications, including weight , straight length and width , curved length and width, plastron length, tail length and their egg laying were recorded. The obtained results were analyzed in the statistical package of social science (SPSS). The results revealed that only Hawksbill turtle (Eretmochelys imbricata) attend these islands for egg laying. Only 45 turtles out of 73 laid eggs. The percentage of egg laying in Henqam in comparison with Hormoz was more. In regard with the weight the minimum was 35 kg and the maximum was 57 kg which showed a high distribution, although the width of them in comparison with the ones in the world was low, relative to the ones in the west of Persian Gulf was high. In comparison between the laid eggs, the result showed that the minimum of laid eggs per one turtle was 75 and the maximum was 126, meanwhile the world standard is between 100 to 160 and in the west of Persian Gulf was 79. It can be concluded that Hawksbill turtles in Persian Gulf are lighter and shorter and lay fewer eggs than the average of the world. It should be mentioned that in the east of Persian Gulf the turtles are bigger , and more laid eggs in comparison with the turtles of the west.
