Composition and diversity of fish species in mangrove ecosystem at Muara Binuangeun, Lebak, Banten

Abstract

Abstract Mangrove ecosystem is an ecosystem in coastal areas that have a high diversity of fish species, and different location has its unique fish composition. Research on mangrove ecosystem at Muara Binuangeun is not yet done and needed to discover the composition and diversity of fish species. Research of composition and diversity of fish species in mangrove 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. Collected samples were preserved with 10 % Formalin Solution and then being identified at the laboratory. In total, 106 fishes were collected from 11 families and 28 species. Istigobius ornatus was the most relative abundant species (19.81 %) and the highest relative frequency too. The diversity index value of mangrove ecosystem was 2.846. The composition of collected fish showed several migrant species from seagrass bed and coral reef ecosystem.
