Abstract
The community structure of macrobenthos in this study depends on the species diversity, richness, and evenness, which are the reflection of the biotic factors. The objectives of this study are to identify macrobenthos species, besides, to assess the community structure of macrobenthic communities. This study was carried out in Kuala Sibuti, Miri, Sarawak. The quadrat transect method was used to obtain the samples (pore water, macrobenthos, and sediment samples). Pore water quality parameters (pH, total dissolved solids, salinity, temperature, turbidity, conductivity, and dissolved oxygen) were measured using Portable Water Quality Meter, and water analysis (ammonia, nitrite, phosphate, and nitrate) were analyzed in the laboratory. In this study, 17 macrobenthos species were identified. Gastropoda is the most dominant Class among the species identified, followed by Polychaetes, Bivalvia, and Clitellata. The most abundant species of Gastropoda are Cerithidea charbonnieri; Polychaetes, Nephtys polybranchia; Bivalvia, Crassostrea rhizophorae; and Clitellata, Glossiphonia sp. respectively. The macrobenthos species is more diverse in Plot 1 (2.006) compared to Plot 2 (0.756) and 3 (1.345). The high diversity of macrobenthos has indicated that the sediment characteristics (sand 95.32%; silt 4.86%) and great pore water quality, turbidity, influenced the species diversity. Hence, the collected data may assist as a baseline for further studies and can also be an approach to illustrating the diversity of macrobenthos.
