Abstract

This study aims to determine the types and abundance of Bivalves in the Intertidal Zone, Karang Papak Beach, West Java, Indonesia. This research was conducted in November 2018. The method of sampling used line transects (line transects) systematically using a 1 x 1 meter quadrant. All types of bivalves found in the quadrant are calculated and identified. The results showed that there were 2 types of bivalves found in the study sites, namely M. micropterus and M. arenaria. The calculation results of the abundance index value indicate that between stations have different values. Abundance based on the moon phase shows that the highest abundance in both species is found in the dark moon phase, this is related to environmental conditions such as the influence of light and the availability of food resources. This data can be used as additional information in determining the management of aquatic resources in that location.
