Eight specimens of Meganthias kingyo were collected from Bitung, North Sulawesi, Indonesia between 2008 - 2010. The specimens were caught from about 70-150 m off Lembeh Island. M. kingyo differs from M. natalensis by having the following characteristics: pores lateral line scales (43 vs. 49); pectoral rays (16 vs. ii.14); body depth (47.1 vs. 51.9); head length (31.0 vs. 38.2), body depth (47.1 vs. 52.9), caudal peduncle depth (12.1 vs. 14.2), pectoral fin length (28.0 vs. 34.3), pelvic fin length (33.6 vs. 31.1), anal fin base length (19.4 vs. 22.2), caudal fin length (66.9 vs. 35.3) and longest dorsal fin ray (48.5 vs. 27.4). Previously, this species has been reported from Houzan-sone, off Miyako and Yaeyama Islands in Okinawa, Japan; and herein is recorded from off Lembeh Island, North Sulawesi, Indonesia.

Distribution and composition of Indonesian Chaetodontid species may vary among different locations. However, illegal fishing practices such as bombing and poisoning on reef ecosystems have significant contribution to environmental degradation and can change the community structure of fish especially that of Chatodontids that act as indicator species in in the given areas. Therefore, it is important to do periodic surveys to know the current condition and their changing. A study on community structure of Chaetodontidae has been conducted from July toAugust 2011 on coral reef ecosystems of the Banda Sea and its adjacent waters including Banggai, Kendari, and Lamalera Islands. Scuba equipment was used and underwater visual census method was applied for collecting the data at 21 stations. A total of 1399 individual Chaetodontid fishes was observed, belonging to thirty species and seven genera, i.e. Chaetodon (20 species), Heniochus (4 species), Forcipiger (2 species), Chelmon (1 species), Coradion (1 species), Hemitaurichthys (1 species), and Parachaetodon (1 species). Chaetodon kleinii was the most dominant species in the Banggai (74,38%) and Lamalera (71,71%). Kendari was characterized by the presence of C. octofasciatus that contributed 55,20%. There were two dominant groups of Chaetodontidae based on the feeding guild. Facultative coral feeder was the most abundance in Banggai and Lamalera, while the most commonChaetodontidae in Kendari belonged to obligate coral feeder. Chaetodontid diversity in Banggai was the lowest compared to that of in other studied areas. Anthropogenic pressure may become a major factor causing the low diversity and studied species richness in the coral reef ecosystem of Banggai waters.

Coastal development of North Molluccas put concern to coral reefs and reef fishes to be a vital regional asset and also a vurnarable consequence toward the development effects. A method used was underwater visual cencus on the permanent belt transect. The selected indicator monitoring used were eight families of reef fishes. Results showed that there were 108 species of reef fishes identified, consist of 31 species indicator fishes of corallivore, 45 species herbivorous fishes and 32 species carnivorous fishes (based on punctuation group). Density means of a corallivorous group is 1,598 ± 283 individual/ha, a herbivorous group is 4,751 ± 1.034 individual/ha, and a carnivorous group is 890 ± 622 ekor/ha, respectively. A mean of reef fish stocks is 420 ± 162 kg/ha that consist of 320 ± 130 kg/ha for herbivorous fishes and group and 100 ± 64 kg/ha for carnivorous fishes. Indicator fish dominance were attained by Chaetodon kleinii, Chaetodon lunulatus, Chaetodon baronessa, Heniochus varius, Chaetodon melannotus, Chaetodon trifascialis, and Chaetodon octofasciatus. Herbivorous fishes (84%) more dominat than carnivorous (16%) in terms of individual composition. Dominant species of herbivorous fishes included Ctenochaetus striatus, Ctenochaetus binotatus, Zebrasoma scopas, Scarus ghobban, Lutjanus biguttatus, Acanthurus pyroferus, Chlorurus sordidus, Chlorurus bleekeri, Siganus vulpinus, and Scarus dimidiatus. The one of carnivorous fishes dominated was only Lutjanus biguttatus. Increasing trend of species numbers and density for corallivorous, herbivorous and carnivorous fishes occured during 2015 and 2017 in majority of study sites. Contrarily, the biomass values not increased in majority of the sampling sites.
