The Abundance and Distribution Patterns of Mud Crabs (Scylla Spp.) In The Ketapang Indah Mangrove Area, Singkil, Aceh
Keywords:
Mangrove crabs, Species richness, Species distributionAbstract
The mangrove crab lives in areas densely covered with mangrove vegetation with muddy or sandy mud substrates. The mangrove crab belongs to the class Crustacea and order Decapoda. Crustaceans are hard-shelled animals, so their growth is characterized by a process of molting. Mangroves are the natural habitat of mangrove crabs. The purpose of this study was to determine the species richness of mangrove crabs (Scylla spp) and the distribution patterns of mangrove crabs (Scylla spp). The research method used was a survey method. The technique for sampling mangrove crabs was random sampling using traps taken from three stations, with three repetitions at each station. The results of the study show that three species were found in the Ketapang Indah mangrove area, namely Scylla serrata, Scylla paramamosain, and Scylla olivacea. The overall distribution of mangrove crabs Scylla serrata and Scylla olivacea was uniform, while Scylla Paramamosain had a aggregate distribution pattern
