Abstract
The research aims to determine the biodiversity and relative abundance of fish in the kumbe River Estuary. The research was carried out from September to November 2022. The sampling method uses proposive sampling techniques. Fish samples were taken using gill nets. Samples were identifird in laboratory Water Resource Management Department. Data analysis used includes- diversity index, uniformity index, dominance index and relative abundance of fish. The results of the research showed that the total number of fish found was 185. The types of fish faound are- Lates calcarifer, Eleutheronema tetradactylum, Mugil cephalus, Selenotoca papuensis, Oreochromis niloticus, Kurtus gulliveri, Thryssa setirostris, Arius talasinus, Trichiurus lepturus, Tetraodontidae. Polydactylus plebejus, Toxotes. The fish diversity index value found at the mouth of Kumbe river estuary 2,29. The uniformity index value is 0,87 and the dominance index is 0,12.
