| description | Bruit Island is located at the northern edge of Rajang Delta under Mukah division in the
district of Daro, Sarawak. There is lacking information of molluscs community in Bruit
Island. The objectives of this study are to document the community structure of gastropod and
bivalve of Bruit Island and to determine the correlation between the community structure and
environmental parameters of water. This study focused on species composition, species
density, species diversity, species evenness and species richness of gastropod and bivalve. The
molluscs were collected by using five replicates of 1m × 1m quadrat within 100m2 plot in
every station on an intertidal area in Bruit Island. A total of 15 species of gastropods and one
species of bivalve were collected and identified. Cerithidea cingulata was the most abundant
species followed by Assimineia brevicula and Nerita lineata. Community structure parameters
were recorded highest at the mangrove habitats whereas the community structure parameters
were recorded lowest at sandy beach habitat. Species diversity and species evenness of
mollusc were strongly significant correlated with size of sediments at p<0.05. Higher
percentage of silt and clay in a habitat resulted in higher diversity and evenness of gastropod
and bivalve. Dissolved oxygen and pH of water also significantly correlated with the species
evenness of gastropod and bivalve in Bruit Island. |
