H. Okan Kamaci, Kursat Firat, Sahin Saka and Musa Bulut

Abstract:
The embryonic development of sharpsnout seabream (Diplodus puntazzo Cetti, 1777) eggs was investigated in detailed for culture conditions. The experiments have been carried out at 24 ± 0.2 ° C. Eggs of sharpsnout seabream were obtained by wild broodstock without hormonal treatment. The average diameters of the eggs and oil globule were determined 0.807 ± 0.008 mm and 0.245 ± 0.008 mm, respectively. Embryonic development stages were observed in every 15 min. Whenever there was an evident difference during the embryonic development, the photographs were taken before or after the due time. Early morula stage, early gastrula stage, 2 somit stage and formation of otolith of eggs were determined 03:00 h, 07:10 h, 15:15 h and 19:30 h after fertilization, respectively. At 24 ± 0.2 ° C, hatching occurred 26:10 h after fertilization.
