Abstract: Sepioteuthis lessoniana is a member of Cephalopoda which has important economic value. Continuous use of Cephalopoda resources can lead to extinction. Efforts are needed to conserve Cephalopoda resources. Factors that influence the success of the conservation of these resources are through breeding cultivation activities. The purpose of this study was to assess the hatching of S. lessoniana eggs in various osmotic and energetic conditions. The method used was an experimental laboratory, using a completely randomized design. The treatment in this study was the difference in media salinity, namely 27 ppt, 30 ppt, 33 ppt, and 36 ppt salinity. Data was collected for media osmolarity and hemolymph, egg energetics, number of hatched and damaged eggs. The calculated parameters were the level of osmotic work, the efficiency of energy utilization, hatching efficiency, and survival. The results showed that the best S. lessoniana hatching occurred at 33 ppt salinity treatment with an osmotic work level approaching the iso-osmotic value of 2.03 ± 0.05 mOsm/lH2O so that the most efficient energy utilization was 90.72% and a high hatch rate was 91%.
