“…This difference is thought to be the influence of the composition of the structure and substrate of the bottom of the waters, which is a limiting factor for the existence of Chaetodontidae fish, especially live coral cover, which is the leading food of Chaetodontidae fish and is therefore used as an indicator fish for assessing the condition of coral reefs (Amrullah et al, 2020). This is by the percentage of coral cover found in the waters of Sironjong Gadang Island, where stations I, II, and III have an average percentage of coral reefs of 5.96%, included in the poor condition category.…”

Sironjong Gadang Island is one of the islands in the Mandeh Tourism area in Pesisir Selatan Regency, West Sumatra, Indonesia. One of the ecosystems affected by tourism activities is coral reefs. Monitoring the coral reefs' condition and the abundance of coral fish in the Chaetdontidae family is carried out to find out this. This research uses survey research methods. The temperature measurement results obtained an average of 30.2oC, current speed measurements received an average of 0.12 m/s, salinity measurements obtained an average of 30 ppt, and brightness measurements show that the brightness of these waters is 9 m. Tide measurements in the waters of Sironjong Gadang Island, carried out on March 7–8, 2023, are double daily tides (semi diurnal tide). Then, the results from the coral reef cover of Sironjong Gadang Island waters obtained a percentage ranging from 2.34 - 12.83%, with an average rate of live coral reef cover of 5.96%, which is included in the poor category. Furthermore, the results at each research station in the waters of Sironjong Gadang Island showed that 54 coralfish individuals were found, with the number of coralfish at each depth ranging from 4 - 10 individuals. The most common types of coral fish are species. Acuminate had 18 individuals; the fewest types of coral fish found were Chaetodon trifasciatus and C. tristichous, each numbering two individuals. There is a solid relationship between live coral reef cover and the abundance of coral fish in the Chaetodontidae family, where live coral reef cover influences the plenty of coral fish by 61.11%, which means that the higher the percentage of live coral cover, the higher the value of coral fish abundance.

“…Indeks keanekaragaman (H') memiliki nilai < 1,00 pada semua pulau, sehingga berdasarkan indeks keanekaragaman oleh Shannon & Weaver (1964), indeks keanekaragaman pada seluruh pulau di kawasan perairan Teluk Paraja masuk pada kategori yang rendah. Rendahnya indeks keanekaragaman pada seluruh stasiun dapat dikarenakan kondisi terumbu karang yang buruk, hal ini sesuai dengan pernyataan Amrullah & Rahmadani (2020), kelimpahan dan keanekaragaman spesies ikan akan meningkat bersamaan dengan bertambahnya tutupan karang hidup. Menurut Odum (1971), indeks keanekaragaman dapat menunjukkan kemampuan adaptasi spesies dengan lingkungannya, semakin kecil nilai indeks keanekaragamannya maka semakin sedikit spesies yang mampu beradaptasi.…”

Fish that spend most of their life cycle and depend on the existence of coral reef ecosystems arereef fish. Butterflyfish (Chaetodontidae) is a family of fish that can live in association with coral reefs and has an important role in coral reef ecosystems, causing butterflyfish to be very sensitive to changes in coral reef conditions. The tsunami in Paraja Bay, Pandeglang Regency, Banten, in December 2018 made a difference in habitat conditions. This significant difference can affect the abundance of fish that live in it, especially butterflyfish. The availability of data onthe community structure of reef fish in Paraja Bay is categorized as "poor data". Therefore, this study was conducted to add more specific data regarding the abundance and community structure of reef fish from the Chaetodontidae family. This research was conducted in February 2022 using the Underwater Visual Census (UVC) method to collect fish data. Data were taken on each side of the four small islands for 16 stations. The depth of the observation station is between 5-6 m. Observations at each station were carried out by placing a 50 m roll meter parallel to the shoreline with a width of 2.5 meters to the right and 2.5 meters to the left, and 5 meters above the roll meter. The result shows that there were 179 individuals found from 4 genera and 14 species of the Chaetodontidae. The species found were Chaetodon collare, C. Kleinii, C. ephippium, C. octofasciatuus, C. rafflesia, C. trifasciatus, C. vagabundus, Chelmon rostratus, Forcipiger longirostris, Heniochus acuminatus, H. pleurataenia, H. singularis, and H. singularis, H. varius. The community structure was analyzed using fish abundance, diversity (H'), dominance (C), and evenness index (E). The highest abundance of butterflyfish was 0.09 ind./m2, and the lowest was on the east side of Oar Island, which was 0.00 ind./m2. The butterflyfish diversity index ranged from 0,61 (Umang Island) to 0.71 (Badul and Mangir Island). The fish evenness index ranged from 0.69-0.84, where the highest value was 0.84 on Mangir Island and the lowest was 0.69 on Oar Island. The highest dominance index has a value of 0.35 on Oar Island, while the lowest is on Mangir Island, with a dominance index of 0.25. Based on these results, we can conclude that the genus Chaetodon has the most significant composition. Based on the community structure result, Paraja Bay’s waters provide equal opportunities for all species but have low species variation. Each species has a small number. It can be known that it is necessary to conserve and maintain coral reef ecosystems to increase the abundance and presence of butterflyfish in the waters of Paraja Bay, Pandeglang, and Banten.
