Species Diversity and Abundance of Marine Molluscs in Mangrove Forest and Seagrass Bed at Kung Krabaen Bay, Chanthaburi Province Species Diversity and Abundance of Marine Molluscs in Mangrove Forest and Seagrass Bed at Kung Krabaen Bay, Chanthaburi Province

Abstract

Diversity and abundance of mollusk at Kung Krabaen Bay was conducted from January to December 2021. Specimen was collected by hand free during lowest tide in mangrove forest and seagrass ecosystem in both species of Halodule pinifolia and Enhalus acoroides. The result found that diversity of mollusks was belonged to 17 family 26 genera and 29 species. Mangrove forest was found highest diversity of mollusk (21 species) whereas seagrass bed H. pinifolia and E. acoroides were found lower diversity (12 and 10 species) whereas the abundances of mollusks were 39% and 13%, respectively. Moreover, statistical analysis showed that abundance of mollusk in each ecosystem was significantly different (p<0.05) but in contrast with abundance in each season was no significantly different (p>0.05). The abundance of mollusks in dry and wet season were 55% and 45%. The relationship between abundance of mollusks and physical factors was no correlated in significantly different (p>0.05).
