Abstract:
This study aims to determine the community structure makrozoobenthos covering types, abundance, diversity, dominance and uniformity makrozoobenthos and to know the content of organic matter in the sediment with an abundance makrozoobenthos Dompas waters. While the benefits of this research are expected to provide basic information in conserving aquatic resources, ecosystems as input for various parties, especially fisheries development planners in business management of Dompas water Bengkalis.

A total of makrozoobentos found at the study site are six species and four class. The six species are Crenatula mytiloides, Nereis virens, Portunus latipes, Cardisona camifex, Littorina nebulosan and Rhinoclavis sinensis. Research describing the abundance and diversity of aquatic makrozoobenthos in Bukit Batu Village District Dompas Bengkalis vary at each research station. To obtain a comprehensive picture of the diversity makrozobenthos Dompas waters around this village, it is necessary to study more closely the expanding area of research that includes round Bengkalis Strait.
