“…The fish species dominant found were Acanthuriada and Caesionidae families. It was in line with Paulangan et al (2019) study, who explained that the Acanthuridae family was one of omnivorous fish that removes coral polyps to get algae that settle in the coral shelter skeleton. It was possible because of the availability of food as an indicator of presence in reef waters area.…”

Abstract. Mujiyanto, Sugianti Y, Afandy YA, Rahayu R, Bidikusuma RA, Nasriri AS, Syam AR, Purnaningtyas SE. 2021. Reef fish community structure in the islands of Paraja Bay, Pandeglang District, Banten, Indonesia. Biodiversitas 22: 4402-4413. Paraja Bay waters have five small islands that coexist with Ujung Kulon National Marine Park and act as a buffer zone for the diversity of fishery resources. This study aimed to assess the reef fishes community structure at small islands in Paraja Bay. Observations were made in 20 locations during August and September 2019 in the five small islands. Reef fishes community structure showed 106 species as included major group (54 species), indicator group (24 species) and target group (28 species), among five small islands, i.e. Badul, Mangir, Oar, Sumur and Umang Islands. The highest reef fishes abundance was founded in Umang Island waters. Several target fish species recorded during the study were mature fish (such as those targeted by fishermen). Only a small proportion were juveniles. Reef fish community structure was categorized as stress community to stable community with its indication was low diversity value, high evenness index, and low dominance. The low diversity index value illustrates that the level of uniformity of reef fish species in Paraja Bay waters is high. This condition is evidenced by each coral fish group's evenness index included in the main species group around 0.93 to 0.98. The target species is 0.88 to 0.99.

Many forests have substantial understorey plants. These plants have an important contribution to soil and water conservation. The similarity index determines the resemblance of species structure and composition in a community. This research is aimed to see the impact and relationship of changes in the allocation of forest areas to the similarity of understorey species. The research was conducted using the line plot sampling method, sized 2 m x 2 m, with the understorey plants observed have been measured from germination to young plant (height 1.5 m). The number of plots in the plantation forest is 480 plots, protected areas 224 plots, and natural forest 96 plots. Determination of the number of understorey plots based on the minimum representative area curve. A Similarity Index was performed to analyze the data. The results indicated that there is an impact of changes in the forest area on the similarity of understorey species. It is known from the low similarity index value at the research location. It is due to the differences in environmental factors at the two locations such as air humidity, air temperature, the intensity of sunlight, and different patterns of forest area management.

Reef fish utilize coral reef ecosystems as a place to live, foraging, spawning and nurturing. This study aims to determine the abundance of species, diversity and biomass of reef fish found in the waters of Ujong Pancu, Aceh Besar district. This research was conducted in October 2017, there were 5 research location. Data was collected using the Underwater Visual Census (UVC) method. The result show that the highest abundance of reef fish was found in waters of Lhok Mata Ie with a value of 5311.71 Ind/ ha. While the lowest abundance of reef fish was found in Tuan Island waters with a value of 896.67 Ind/ ha. Overall diversity of Ujong Pancu waters reefs is included in the medium-high category. The highest average biomass of reef fish is found in the water of East Batee Island with a value of 100.69 Kg/ ha. While the lowest average biomass of reef fish is found in the waters of West Batee Island with a biomass value 23.87 Kg/ ha. Keywords : Abundance, biomass, diversity, reef fish, Ujong Pancu
