Abstract

Beach tourism often considered as an environmentally friendly industry and has little or no negative impact on the environment. However, there are concerns that these activities also have the potential to generate negative impact on biodiversity in coastal areas including seagrass beds and their associated fauna. This study addressed to compare fish assemblages inhabiting the seagrass beds of Bama and Kajang beaches, Baluran NP in correlation of tourism activities (trampling, snorkeling, etc.) where Bama are more frequently visited by tourists. In-situ visual census observation at five belt transect (500 m-2 wide of area) were conducted in June 2017 on both beaches. Species richness and fish density in Kajang (47.2±5.81 species, 353±94.53 individual/500m-2) were higher compared to Bama (20±3.94 species, 146±25.66 individual/500m-2). In general, community structure of fish in both beaches was relatively similar and dominated by Pomacentridae, Apogonidae, Caesionidae, Labridae, Nemipteridae, Siganidae and Lethrinidae. At the level of species, the communities dominated by Pterocaesio sp, Apogon hartzfeldii, Scolopsis affinis, Siganus canaliculatus, Dischistodus prosopotaenia and Halichoeres schwartzii, respectively. Values of Shannon-Wiener index (H’) ranged from 3.20 to 3.50 in Kajang and 2.055 to 2.441 in Bama, showing higher species diversity in Kajang. Although there are differences in species richness and abundance of fish in both locations, it is apparently not only caused by anthropogenic factors, but can also be caused by differences in variation of habitat within seagrass bed at both locations
