We feed Lunatica gilva under the experimental conditions, and observe breeding and embryo's growth, optimizing larva cultivation process. After dealing with fresh water, larva survival rate in 96h is 26.5%, higher than the untreated group that is 9%. The experiment feeding different bait to larva showed that feeding diatom is better to the growth of larva, and diatom is appropriate for the early period of larva cultivation.
