The effects of different levels of illumination on common dentex Dentex dentex (L.) larvae have been examined. Illumination affected the relationships between total length and digestive tube length, total length and oil globule volume, and total length and yolk sac. The relationship between total length development and yolk sac utilization in dark and light conditions was found to be significant ( P <0.05). However, it was determined that the relationship between digestive tube development and oil globule absorption was not significant ( P >0.05). Besides, there is no effect of different light intensities on absorption of yolk sac and oil globule and digestive tube development ( P >0.05). In addition, total length development was not significant ( P >0.05). Survival rate was found to be not significantly different in dark conditions ( P >0.05).
