Binh Thuan province is located in the South Central Coast of Vietnam with favorable conditions for living coral reefs. The coral reefs were mainly investigated in coastal water areas and Phu Quy island, meanwhile other areas such as the banks and rocky islands seem to lack information. This study was conducted to evaluate the species composition and distribution of coral reef fish communities in the Royal Bishop banks and around rocky islands in Julia shoal in the offshore waters of Binh Thuan province in April 2019. A total of 151 species belonging to 86 genera and 33 families of coral reef fishes were recorded. Among them, 4 species for the first time recorded in Vietnam are Helcogramma striata (Hansen, 1986) (Tripterygiidae), Pseudanthias squamipinnis (Peters, 1855) (Serranidae), Bodianus bilunulatus (Lacepède, 1801) and Coris aygula (Lacepède, 1801) (Labridae). The total average density of coral reef fish in the offshore waters of Binh Thuan is quite high at 1,104.9 ± 617 individuals/250 m2, most of them are small sized fish and ornamental fish group, the large sized fish and target fish group accounts for a relatively low rate, but their density here is much higher compared to that in the coastal waters of Binh Thuan province. The comparative analysis also shows that sites in coral reef around rocky islands have species richness and density of coral reef fish higher than the bank area.

Healthy reefs provide a habitat for an immense number of fish that come in a variety of shapes, sizes, and colours. No other natural habitat in the ocean shows this diversity and abundance. About a quarter of all marine species may be found on coral reefs even though this habitat occupies only one or two per cent of the area of the earth. ‘Reef fish and other major predators’ describes the diverse feeding ecology of reef fishes; coral reef predators such as the colourful crown of thorns starfish, Acanthaster plancii; symbiotic relationships between different species of fish or with different invertebrates; and the dangers of overfishing in reef communities.

Abstract The corallivorous Crown-of-Thorns Starfish (CoTS, Acanthaster spp.) has been linked with the widespread loss of scleractinian coral cover on Indo-Pacific reefs during periodic population outbreaks. Here, we re-examine CoTS consumption by coral reef fish species by using new DNA technologies to detect Pacific Crown-of-Thorns Starfish (Acanthaster cf. solaris) in fish faecal and gut content samples. CoTS DNA was detected in samples from 18 different coral reef fish species collected on reefs at various stages of CoTS outbreaks in the Great Barrier Reef Marine Park, nine of which had not been previously reported to feed on CoTS. A comprehensive set of negative and positive control samples confirmed that our collection, processing and analysis procedures were robust, although food web transfer of CoTS DNA cannot be ruled out for some fish species. Our results, combined with the (i) presence of CoTS spines in some samples, (ii) reported predation on CoTS gametes, larvae and settled individuals, and (iii) known diet information for fish species examined, strongly indicate that direct fish predation on CoTS may well be more common than is currently appreciated. We provide recommendations for specific management approaches to enhance predation on CoTS by coral reef fishes, and to support the mitigation of CoTS outbreaks and reverse declines in hard coral cover.

AbstractStable isotopes of carbon and nitrogen characterize trophic relationships in predator–prey relationships, with clear differences between consumer and diet (discrimination factor Δ13C and Δ15N). However, parasite–host isotopic relationships remain unclear, with Δ13C and Δ15N remaining incompletely characterized, especially for helminths. In this study, we used stable isotopes to determine discrimination factors for 13 parasite–host pairings of helminths in coral reef fish. Differences in Δ15N values grouped according to parasite groups and habitat within the host with positive Δ15N values observed for trematodes and nematodes from the digestive tract and variable Δ15N values observed for cestodes and nematodes from the general cavity. Furthermore, Δ13C values showed more complex patterns with no effect of parasite group or habitat within host. A negative relationship was observed between Δ15N and host δ15N values among different host-parasite pairings as well as within 7 out of the 13 pairings, indicating that host metabolic processing affects host-parasite discrimination values. In contrast, no relationships were observed for Δ13C values. Our results indicate that parasite group, habitat within host, and host stable isotope value drive Δ15N of helminths in coral reef fish while their effect on Δ13C is more idiosyncratic. These results call for use of taxon- or species-specific and scaled framework for bulk stable isotopes in the trophic ecology of parasites.

The branching structure of the coral colonies from the genusMilleporaprovides substrate, shelter, and food resources for several reef organisms, such as fish and invertebrates. The present work analysed the association and behaviour of reef fish on the fire coralMillepora alcicornisandM. brasiliensisfrom September 2010 to February 2011, on the coastal reefs of Tamandaré, north-east Brazil. A total of 473 reef fish individuals of 27 species were sighted associated with the coral colonies, mainly composed of juveniles (65%). The most frequently observed behaviours were sheltered/stationary and swimming close to the coral; however, individuals were also observed foraging and breeding amongMilleporaspp. branching colonies. The agonistic behaviour performed byStegastes fuscusindividuals was highlighted in the present study, especially againstChaetodon striatus, Diodon holacanthusandOphioblennius trinitatisindividuals.Milleporaspp. hydrocorals are ecologically important for juvenile and adult reef fish belonging to several trophic guilds. The complex structure of the coral colonies provides a wide variety of ecological functions on coral reefs (e.g. shelter, reproduction area, food and even territory). Nevertheless, the abundance of branching fire coral in Brazilian reefs have been declining over the past years; therefore, efforts must be made to protect this key habitat.

Ekosistem terumbu karang merupakan kekayaan sumberdaya laut yang memiliki peranan penting dalam mendukung kehidupan berbagai organisme perairan. Salah satu organisme yang memiliki ketergantungan hidup pada terumbu karang adalah ikan karang. Hal ini dikarenakan ikan karang melalui fase hidup sebagian atau seluruhnya di terumbu karang, sehingga terumbu karang menjadi tempat tinggal, tempat mencari makan, tempat berlindung dan tempat berkembang biak.  Penelitian dilaksanakan pada bulan Mei 2017, dengan tujuan untuk mengetahui persentase tutupan karang hidup dan kelimpahan ikan. Serta hubungan persentase tutupan karang dengan kelimpahan ikan karang pada sisi Barat dan Timur Pulau Menjangan Kecil kedalaman 1 dan 3 meter. Metode yang digunakan adalah metode observasi lapangan, dengan metode sampling menggunakan transek garis (line transect) pada data karang dan visual census untuk data ikan sepanjang 25m. Hasil dari penelitian ini menunjukkan bahwa Persentase rata-rata tutupan karang yang diperoleh pada kedalaman 1 meter sisi Barat adalah 73,39%, sedangkan pada kedalaman 3 meter adalah 85,97%. Persentase tutupan karang pada kedalaman 1 meter sisi Timur adalah 63,73%, sedangkan pada kedalaman 3 meter adalah 77,61%. Secara keseluruhan kondisi terumbu karang masih tergolong baik. Kelimpahan rata-rata ikan pada sisi Barat kedalaman 1 meter adalah 70 individu/125 m2, sedangkan pada kedalaman 3 meter adalah 232 individu/125 m2. Kelimpahan ikan sisi Timur kedalaman 1 dan 3 meter masing-masing adalah 49 dan 138 individu/125 m2. Hasil perhitungan indeks korelasi secara keseluruhan menghasilkan nilai 0,8415 dengan koefesien determinasi sebesar 0,7081. Hal ini menunjukkan bahwa pola hubungan persentase tutupan karang dengan kelimpahan ikan karang kuat (signifikan) dan positif (searah). Coral reef ecosystem is a wealth of marine resources that have an important role in supporting the life of various aquatic organisms. One of the organisms that has a living dependence on coral reefs is reef fish. This is because coral fish through a partial or complete life phase on the coral reef, so that coral reefs become a place to live, a place to find food, shelter and breeding ground. The study was conducted in May 2017, with the objective of knowing the percentage of live coral cover and fish abundance. And the correlation of percentage of coral cover with abundance of reef fish on West and East side of Menjangan Kecil Island depth of 1 and 3 meters. The method used is field observation method, with sampling method using line transect on coral data and visual census for fish data along 25m. The results of this study indicate that the average percentage of coral cover obtained at a depth of 1 meter west side is 73.39%, while at a depth of 3 meters is 85.97%. The percentage of coral cover at depth of 1 meter East side is 63,73%, while at depth 3 meter is 77,61%. Overall the condition of coral reefs is still quite good. The average abundance of fish on the west side of 1 meter depth is 70 individuals / 125 m2, while at 3 meters depth is 232 individuals / 125 m2. The abundance of fish on Eastern side, depth of 1 and 3 meters respectively were 49 and 138 individu / 125 m2. Result of calculation of correlation index as a whole yield value 0,8415 with coefficient of determination equal to 0,7081. This shows that the pattern of correlation of percentage of coral cover with abundance of reef fish is strong (significant) and positive (unidirectional).

Complex Architecture

Coral reefs is a center for biodiversity in the world with a complex architecture and has an aesthetics value. It also offers beneficial for human being in many aspects such as economics, social and culture. Research was conducted in July 2016 and aim to understand community structure and biomass of coral reef fishes in Tapanuli Tengah waters. Result from all stations in Tapanuli Tengah waters showed that 49 species from seven families of economically reef fish i.e.  Acanthuridae, Serranidae, Haemulidae, Lutjanidae, Lehtrinidae, Siganidae and Scaridae were found. Density average of those seven families was 163 individual/350 m<sup>2</sup> or 4668 individual/ha with biomass average of 1.564 ton/ha. Moreover, biomass from other target fishes from nine families was accounted as 0.56 ton/ha. On the other hand, over all coralifore fish represented by Chaetodontidae was eight species from two genus, namely <em>Chaetodon</em> and <em>Heniochus </em>with four species. The density from family Chaetodotidae varies among station between 3-28 individual/350 m<sup>2</sup>

Scientific Survey

A 573 species-long checklist of the fishes in this 50 km2 tropical marine park was created predominantly by combining an unpublished scientific survey from 1992 with a hobbyist’s large photograph collection from between 2006 and 2009. Of the Indo-Pacific region’s coral reef-associated fish species, 15.2% are found here. Drawn from 83 families, the most speciose are Pomacentridae (71), Gobiidae (68) and Lab-ridae (55). A regression formula using the Coral reef Fish Diversity Index (CFDI) for species seen in 1992 suggests the park hosts 464 species, compared with the CFDI-based estimate of 495 based only on da-ta collected between 2006 and 2009, and 596 for the combined Index. With only 62% of the Index’s species seen both in the earlier and later lists, the utility of the CFDI is questionable at a site or over a time-span like this.

Large-scale patterns of species diversity in the gastrointestinal helminth faunas of the coral reef fish Epinephelus merra (Serranidae) were investigated in French Polynesia and the South Pacific Ocean. The richer barrier reef community in French Polynesia supported richer parasite communities in E. merra than that on the fringing reef. While parasite communities among fish from the same archipelago were similar, differences in potential host species and the distance between archipelagos may have contributed to a qualitative difference in parasite communities between archipelagos. Digenean community diversity in coral reef fishes was greater in the western South Pacific, following similar patterns in free-living species. However, overall species diversity of camallanid nematodes of coral reef fishes does not appear to have been similarly affected.
