Mangrove crab is one of the mangrove inhabitants that has high economic value so that it is potential to be cultivated using silvofishery system. This research was conducted in the mangrove area of Mandalle Village, Pangkep Regency, South Sulawesi, Indonesia. The objective of this research was to compare the survival, growth, and biochemical composition of the mangrove crab (Scylla olivacea) maintained by a silvofishery system that was stocked with the different lunar phases. The research container used a fixed cage made of bamboo in a circular shape with a diameter of 2.25 m. The test animals used were mangrove crabs (S. olivacea) weighing 150-160 g from collectors in Pallime Village, Cenrana District, Bone Regency, South Sulawesi and reared for 30 days. The study consisted of 4 treatments with 3 replications each. The four types of treatment are differences in the beginning of the different phases of the moon, namely: new moon, quarter, full moon, and three quarters. The research data were analyzed using the Kruskal-Wallis analysis and the Mann Withney U test. The results of the Kruskal-Wallis analysis showed that the difference in the moon phase had no significant effect (p> 0.05) on survival, but had a significant (p <0.05) effect on survival. growth and body biochemical composition of mangrove crabs (S. olivacea). The best growth and biochemical composition of crab bodies are produced during the new moon phase.
