摘要

Research of composition and diversity offish species in seagrass bed ecosystem at Muara Binuangeun, Lebak, Banten, had been conducted in May and November 2015. Catch per Unit of Effort (CPUE) was used as a method with push net and boat net as fishing gear. Fishing was conducted during low tide.

Moolgarda sp. was the most relative abundant species (17,13 %) and Istiblennius edentulus was a fish species with the highest relative frequency . Diversity index value of seagrass bed ecosystem was 2,973. Different sampling time showed the different composition offish, in an example of Arothron immaculatus.
