Relationship of mangrove snail’s abundance (Cerithidea sp.) with mangrove density at mangrove ecosystem in Banda Aceh and Aceh Besar

Abstract

Abstract Mangrove snails are aquatic biota that inhabit in the mangrove ecosystem, they lives attached to mangrove trees or scattered on the substrate surface. The purposes of this study were to identify the species, distribution pattern, the abundance of mangrove snails (Cerithidea sp.) and their correlation with mangrove density, water and soil characteristics in mangrove ecosystem, Banda Aceh and Aceh Besar. The research sampling was started in April to May 2022. The samples were collected from 5 stations, and purposive sampling method was applied in order to select the sampling station. The results discovered that the species of Cerithidea was Cerithidea cingulate, and the highest abundance was 18 individuals/m2 (station 1). Moreover, the lowest abundance was at station 5 as many as 10 individuals/m2, and other stations showed the abundance of C. cingulata was 15.67 individuals/m2 (station 2), 14.67 individuals/m2 (station 4), and 13 individuals/m2 (station 3) respectively, with a uniform distribution pattern at each station. There was no significantly correlation between mangrove density and the abundance of mangrove snails as well as the relationship between the abundance of mangrove snails with the characteristics of water and soil where PSig. > 0.05.
