“…Fish biomass was higher than in most other known coral reefs in Indonesia and the wider Coral Triangle region (Campbell et al 2020;Ceccarelli et al 2021). In particular, the biomass of large and predatory fishes, species targeted by fisheries, exceeded the typical biomass reported in Indonesian coral reefs (Welly et al 2012;Wouthuyzen et al 2018;Currier et al 2019;Ceccarelli et al 2021). At 33.6%, hard-coral cover was relatively low compared with other sites in the Banda region, which frequently reaches over 50% hard-coral cover (Currier et al 2019;Ceccarelli et al 2021;Purwanto et al 2022).…”

Context. The health of coral reefs is declining rapidly across the world because of anthropogenic impacts. In the mega-diverse Coral Triangle, the consequences of chronic overfishing and human use are worst near coastal population centres. Aims. The remote islands and reefs in the centre of the Banda Sea (Indonesia) remain largely unstudied, but their distance from populated areas could provide protection from fishing. Methods. We conducted the first visual census surveys of coralreef communities at the uninhabited Lucipara group in the Banda Sea. Key results. Sites showed medium to high coral cover and fish assemblages with high biomass, including abundant large predatory species. All sites exceeded the fish biomass conservation target of 1150 kg ha -1 proposed by McClanahan et al. (2015), by a factor of ~2-10. Benthic cover explained >50% of variance in fish abundance and diversity, with submassive corals, Dendrophyllia spp., and bare rock as key predictors. Conclusions. Our results suggested that Lucipara's reefs are among the healthiest in Indonesia, likely owing to their remoteness. However, this remoteness might also hamper policing against destructive fishing practices, highlighting a conservation gap. Implications. Lucipara's reef communities should be protected in a time of global coral-reef declines.

“…This contrasts with the findings of Hartati et al (2010), who discovered that the composition of muroami net catches in the Seribu Islands, Indonesia, is dominated by Goldband fusilier (Pterocaesio chrysozona), Redbelly yellowtail fusilier (Caesio cuning), both from Caesionade family and Yellowstripe scad (Selaroides leptolepis) from Carangidae. Furthermore, the families Acanthuridae, Lutjanidae, Scaridae, Siganidae, Labridae, and Lethrinidae dominate the diversity of reef fish in Banda Sea waters [19]. WNP is dominated by Acanthuridae (Surgeonfishes), Scaridae (parrotfishes), and Serranidae (groupers) [20], and Staring Bay, Southeast Sulawesi are dominated by Acanthuridae, Caesionidae, Haemulidae, Labridae and Lutjanidae [21]).…”

Wakatobi National Park has a diverse fish population, and its conservation potential for reef fish resources is quite large. As a result, to be sustainable, the exploitation of these resources must be properly managed. This study aims to look into the characteristics of reef fish fisheries, such as species composition, catch, fishing ground, and fish length. The outcomes are hoped to be beneficial in monitoring the management of the resources. This research was conducted in April-November 2018 in Wakatobi, Indonesia. Analytical methods process the data. The results showed that gold spotted rabbitfish (Siganus punctatus), parrotfish (Hipposcarus longiceps), emperor (Lethrinus lentjan), grouper (Epinephelus sp), and trevallies (Caranx sp) dominated the total catch from muroami, speargun, and hand line. Muroami boats have a higher average CPUE (212 kg/trip/month) than speargun (29.0 kg/trip/month) and handlines (13.0 kg/trip/ship). Some of the reef fish caught in Wakatobi National Park is small and immature. Muroami net, speargun, and handline fishing are mostly done in the southern part of the Wakatobi National Park area, around Binongko Island. One of the management actions undertaken by Wakatobi fishermen is fishing inside the management zone that has been established, namely the local use zone.

“…Generally, they have small sizes and beautiful colors, so they are well-known as ornamental or aquarium fish [4]. This method has become a standard operating procedure (SOP) for monitoring reef fishes in the Great Barrier Reef, Australia [5], which is then well used in many other tropical countries [6]. During the UVC transect, some identification books are used as references [7][8][9][10][11].…”

Derawan Island, East Kalimantan Province, is located in the coral triangle, the center of mega biodiversity of the world's marine life, including reef fish. In this study, reef fish data were collected from 1994, 2003, and 2019 at six islands (Panjang, Derawan, Samama, Sangalaki, Kakaban, and Maratua) in Derawan Islands using the Underwater Visual Census (UVC) technique. The analysis results focused on herbivores, carnivores, and corallivores reef fish show that the total species diversity and abundance in 1994, 2003, and 2019 amounted to 116 species (5,268 fish/ha), 93 species (2,664 fish/ha), and 104 species (5,332 fish/ha), respectively. Those reef fishes decreased from 1994 to 2003 due to overexploitation but increased again in 2019, especially Acanthurid, Scarid, and Lutjanid fish taxa, possibly due to local government conservation regulations. Biodiversity and abundance were found higher in the Kakaban and Maratua Islands for herbivorous fish (>25 species, >3,500 fish/ha) followed by carnivores and corallivores (±20 species, ±2,000 fish/ha) than in other islands. The diversity of corallivores, herbivores, and carnivores was moderately correlated with live coral cover with R2 of 0.78, 0.77, and 0.61, respectively, but low for fish abundance. Long-term reef fish monitoring is necessary to know coral reef health in this area.
