Abstract

The bivalvia class is a class within mollusca that includes all types of shellfish that have a pair of shells. The aim of this research is to determine the structure of the bivalve community in the coastal waters of Poton Bako, East Lombok. This research was conducted on the coast of Poton Bako, Jerowaru, East Lombok. This research uses a proportional sampling method with quadratic transects. This research variable includes type and bivalves. In this study, 275 individuals of bivalve species were found. The research results show that the ecological condition of Poton Bako is in the relatively good category because the level of Bivalvia diversity is moderate at 1.38 with a high evenness index of 0.60 and a low dominance index of 1.13. In this research, it is necessary to carry out further research regarding distribution patterns, exploitation rates, characteristics of pemadak, and conservation efforts.

Abstract

Gastropoda is a class with the biggest number of species, since a class of Mollusca phylum is generally effectively adjusted to different sorts of marine and freshwater territories to earthbound conditions. So a study was conducted on the diversity of Gastropoda species in the Bale Mangrove Poton Bako East Lombok area with the aim of knowing the types of gastropods that exist in the area. The method used in this study is the quadrat transect method. The results of research on the diversity of gastropod species in the Bale Mangrove Poton Bako East Lombok area found 6 species of Gastropoda including Cerithidea sp, Telebralia sulcata, Nerita undata, Telescopium telescopium, Chicoreus capucinus, Indothais gradate. The average diversity index value of the three stations is H′ = 1.41262991 which means that the diversity of Gastropods in the Bale Mangrove Poton Bako Area of East Lombok is moderate diversity.
