Abstract

A popular tourist destination known for its colorful coral reefs is Kaliage Island, part of the Seribu Archipelago. The UVC (Underwater Visual Census) method was used in a recent study to examine reef fishes’ trophic levels, ecological roles, and community structure. Dominance, evenness, and diversity indices were used to investigate community structure. The results revealed 3,117 fish from 54 species, 16 families, and 32 genera on the reef. The two most notable species within the family Pomacentridae were Pomacentrus alexanderae and Amblyglyphidodon curacao. Fish with major, target, and indicator functions accounted for 85.98 percent, 11.29 percent, and 2.73 percent of the fish population with ecological roles, respectively. The trophic distribution of fishes revealed that 45.01 percent were omnivores, 23.10 percent were planktivores, 19.19 percent were carnivores, 9.46 percent were herbivores, and 3.24 percent were coral eaters. The analysis showed that the reef fish community was balanced and not dominated by any species, with diversity, evenness, and dominance indices of 2.53, 0.87, and 0.01, respectively. For conservation efforts throughout the Seribu Archipelago, this study provides important insights into the stability and health of the reef ecosystem on Kaliage Island.
