Abstract: In this study, the development of European Sea Bass (Dicentrarchus labrax L., 1758) eggs was investigated at different temperatures. The experiments were carried out at 15ºC and 17ºC. The average diameters of the eggs were determined tobe approximately 1.162±0.004 mm. The embryonic development of the eggs was observed every hour and then photographed. The hatching rates were found to be 84.8-89.4% at 15ºC and 82.3-86.3% at 17ºC, respectively. Hatching of the larvae took 87 hours at 15ºC and 69 hours at 17ºC.
