... is a large coastal coral reef area with 6,260 Ha of coral cover near the North Natuna Sea or South Chinese Sea ( Vo et al. 2013). Eleven small islands in twelve site locations in Anambas Marine Protected Area (MPA) were monitored in 2015 and 2019 ( Figure 1) to quantify benthic community structure and reef fish composition (species richness, density, and biomass) and the coordinate location of each island and site were presented (Table 1). The coral reef sites were selected in close distance to the shore, and some reef sites had different reef structures, including fringing reef, patch reef, long reef flat, and reef slope. ...

... Prosedur pengambilan data ikan menggunakan Belt Transect dilakukan berdasarkan standart dasar prosedur Reef Health Monitoring Program (Giyanto et al., 2014) dimana untuk pemantauan biodiversitas ikan terumbu karang Belt Transect yang digunakan sepanjang 70-meter dengan lebar pengamatan sisi sebesar 5-meter (2.5-meter sisi kiri dan 2.5-meter sisi kanan) sehingga luasan total pemantauan biodiversitas ikan karang adalah sebesar 350 m 2 . Berdasarkan Reef Health Monitoring Program prosedur kelompok ikan karang yang didata dibagi menjadi 3 famili ikan yaitu Ikan Bibir Tebal (Haemulidae), Ikan Kakap (Lutjanidae) dan Ikan Kerapu (Serranidae) dimana pemilihan kelompok ikan karnivora ikan ini memiliki fungsi sebagai mempertahankan keseimbangan ekosistem dengan cara mengendalikan kelompok ikan lainnya dengan status trofik yang lebih rendah (Obura & Grimsditch, 2009) dan ikan ini merupakan ikan target untuk ditangkap oleh nelayan karena serta memberikan ketahanan pangan (Allison et al., 2013;Dwirama Putra et al., 2018;Hoegh-Guldberg et al., 2009;Putra et al., 2021). ...
Ikan ekonomis penting yang Sebagian besar merupakan ikan karnivora yang hidup di terumbu karang (Haemulidae, Lutjanidae dan Serranidae) memiiliki perananan yang sangat penting karena mereka menyediakan sumber daya pangan, sumber pendapatan bagi masyarakat lokal, serta berkontribusi pada ekonomi. Penelitian ini bertujuan untuk mengetahui kondisi komunitas ikan karnivora (Haemulidae, Lutjanidae dan Serranidae) di Perairan Lingga. Metode Pengambilan sampel menggunakan Underwater Visual Census (UVC) dengan Belt Transect sepanjang 70-meter dengan lebar pengamatan sisi sebesar 5-meter dari 12 titik stasiun penelitian yang tersebar di Perairan Kabupaten Lingga. Hasil Penelitian menunjukan bahwa terdapat 3 jenis ikan dari famili Haemulidae, 6 jenis ikan dari famili Lutjanidae dan 5 Jenis ikan dari famili Serranidae. Populasi ikan karnivora terbesar yang ditemukan di perairan Lingga yaitu dari jenis Lutjanus corponatatus.
... Protecting coral reefs is the responsibility of the wider community, the government and local communities, such as the application of Marine Protected Areas and other conservation areas (Putra et al. 2021;Sektiana et al. 2022). Implementing conservation area priorities requires an understanding of the spatial distribution of richness and the organization of fish assemblages (Rosdianto et al. 2021b (Razak et al. 2022). ...
Sempu Island is designated as a nature reserve which is surrounded by a fairly high diversity of coral reefs. Since the high activities of fishing ports near this island, the anthropogenic pressure seriously became a threat to the biodiversity of coral reefs in this nature reserve. Continuous observation of reef fish is an important activity to monitor the coral reef health condition. Since then, bimonthly monitoring using an underwater visual census has been conducted from October 2021 to May 2022. Based on these observations obtained that the average reef fish abundance was in the "low" category, namely 0.516 ind/m2 in October 2021, 0.527 ind/m2 in December 2021, 0.522 ind/m2 in February 2022, and 0.378 ind/m2 in May 2022. The abundance of reef fish obtained consisted of three categories: indicators, targets, and majors. Overall, the Pomacantridae family, from the major fish category, has the largest abundance compared to other families. While the range of coral coverage was 6-21.3%, which was included in the "bad" category. There was a relationship with a value of 0.462 (medium) between coral cover and fish abundance. The abundance of reef fish at 21.4% was influenced by coral cover, while the remaining 78.6% was influenced by other factors outside of the tested variables. The decline in reef fish abundance in 2015-2022 can be caused by a decrease in coral cover in the Sempu Strait.
Coral fish are one of the marine biotas that are highly sensitive to changes in coral reef ecosystems. Therefore, the presence or absence of specific reef fish species can describe the condition of coral reefs. The objective of the current study is to investigate the relationship between the biodiversity and abundance of Chaetodontidae fish and the live coral cover at 13 locations in the Spermonde area, Makassar City. Reef fish were counted using the Underwater Visual Census method. Coral cover percentages were determined using the Underwater Photo transects method. The results found 348 individuals of the Chaetodontidae family, comprising 21 species from four genera. The mean live coral cover categories in Spermonde were in pretty good condition (27.83%). Chaetodontidae in Spermonde Island was not diverse (mean H = 1.74) and not abundant (mean abundant = 721 ind./ha). There was a weak correlation between the diversity of Chaetodontidae and live coral cover, and also weak correlation between the abundance of Chaetodontidae and live coral cover in Spermonde Island, with R2 determination coefficient linear regression were 0.1697 and 0.0471, respectively.
The Anambas Islands is one of richest marine biodiversity area in western part of Indonesia, especially for species appeared in coral reef ecosystems. However, as in other parts of the world, climate change and increased human activities pose threats to the ecosystem’s sustainability. Efforts to maintain the balance of the ecosystem in Anambas Islands have been conducted by stating the Anambas Islands and its surrounding sea as a Marine Protected Area (MPA). Here, we review the studies featuring Anambas Island MPA in ecosystem resilience of the islands. From this review, we suggest that oceanographic parameters, especially marine biogeochemistry parameters, should be further utilized to provide environmental data to be used for policy development in the MPA management. Further research and development using marine biogeochemical parameter monitoring/assessment should be taken into consideration by relevant stakeholders in order to achieve MPA’s objectives.
