The fisheries potency in the estuary of Rawa Mekar Jaya Village is high. A research aims to determine the fish community structure in that estuary was conducted in April-July 2019. Fish samples were taken in 3 stations, in the mangrove area (ST-1), reforestation mangrove area (ST-2) and around the residential area (ST-3). The fishes were captured using fishing rod, net traps (mesh size 1-2 inches) and scoop net (mesh size 0.5 cm). Fish was sampled everyday for 10 days period. Results shown that the caught fish consisted of 13 species that are belonged to 12 families. Diversity Index (H ') 2.01–2.31, uniformity index (E) 0.87-0.96 and dominance index (D) 0.10–0.16. The water quality in the estuary were as follows; temperature of 28-300C, the current speed 0.011-0.041 m/sec, brightness of 43-45 cm, salinity of 1,5-15 ‰, dissolved oxygen 3.25-4.16 mg/L and pH of 5-6. Data obtained indicates that community structure of fish can be categorized as medium (stable).
