The Effect of Different Moon Phases to the Dynamics of Total Cholesterol and Glycogen Content of Mangrove Crab (Scylla Olivacea) Cultured with Silvofishery System
Journal Title: International Journal of Zoology and Animal Biology - Year 2021, Vol 4, Issue 1
Abstract
Scylla olivacea is one of mangrove crab species commonly found in South Sulawesi and has the potential to be cultivated using the silvofishery system. This research was conducted in the mangrove area of Mandalle Village, Pangkep Regency and South Sulawesi, Indonesia. The objective of this research was to compare the total cholesterol and glycogen contents of mangrove crabs (S. olivacea) maintained by the silvofishery system that was stocked with the beginning of different moon phases. The research container used a fixed cage made of bamboo in a circular shape with a diameter of 2.25 m. The tested animals used were mangrove crabs weighing 150-160g from collectors in Pallime Village, Cenrana District, Bone Regency, South Sulawesi and reared for 30 days. The study consisted of four treatments with three replications each. The four types of treatment were the differences in the beginning of the different phases of the moon, namely: new moon, quarter, full moon, and threequarters. 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 cholesterol content, but had a very significant effect (p <0.01) on the glycogen content of mangrove crabs. The best glycogen content of crabs is produced during the new moon phase.
