Abstract :
The diversity and abundance of fishare important indicators of ecosystem health. This study aimed to analyze the diversity and abundance of freshwater fishesin the Kalong Floodplain (KF), Ogan Komering Ilir Regency (OKIR), Indonesia. Sampling was conducted during the rainy season, from February to June 2023. Fish samples were collected at three sampling stations. Fish were captured using traditional fishing gear used by local fishermen. All data were analyzed to determine the fish diversity index and relative abundance. A total of 3414 specimens, representing 33 species belonging to 5 orders, 16 families, and 26 genera, were documented during the sampling period. Cyprinidae was the leading family, with Osteochilus vittatus having the highest relative abundance. The lowest abundance were Syncrossus berdmorei and Labeo chrysophekadio. The Shannon-Wiener diversity index, Simpson s dominance index, and evenness index were 1.50, 0.03, and 0.05, respectively. These results indicate that the diversity of freshwater fish species in KF is in the medium category. This data provides information about the biodiversity of fish in the KF and can be useful for the planning of fisheries activities and the setting of precedents for future studies and conservation programs.
