Hal ini menyebabkan penangkapan jenis ikan karang yang semakin langka ini menjadi cukup intensif. Saat ini populasi ikan napoleon cenderung menurun dan akan semakin sedikit jika dilakukan penangkapan tanpa batas, meskipun jenis ikan ini telah dilindungi (Appendix II CITES dan KEPMEN No.37/KEPMEN-KP/2013). Penelitian ini dilakukan dengan tujuan untuk menganalisis kepadatan populasi ikan napoleon dan status pemanfaatannya. Untuk menghitung kepadatan ikan digunakan metode sensus visual (UVC). Untuk mengetahui status pemanfaatan dilakukan sebaran frekuensi panjang ikan, yang dilanjutkan dengan penghitungan laju eksploitasi. Hasil analisis menunjukkan bahwa kepadatan ikan napoleon di sekitar perairan Sinjai (Sulawesi Selatan) adalah rendah (1,8 individu/ha). Dari penghitungan laju eksploitasi, diperoleh gambaran bahwa populasi ikan napoleon di perairan sekitar Sinjai-Sulawesi Selatan telah mengalami lebih tangkap. Dari hasil ini disarankan agar perdagangan ikan napoleon masih tetap diperbolehkan dengan syarat mengikuti ketentuan ukuran dan kuota ekspor. Estimasi kuota ekspor ikan napoleon harus berdasarkan data biologi dan dinamika populasi ikan tersebut agar reproduksi alamiah ikan napoleon dapat berlangsung seimbang dengan tingkat eksploitasinya.

Some areas in Indonesia are still doing the fishing business. Since the napoleon fish was registered in the IUCN red list & Appendix II of CITES, the export quota of 3,600 fishes per year was applied up to the year 2011. In order to support the evaluation size in the water bodies around Sinjai and Bone of the determination of napoleon fish protection status, this study aims to determine fish population South Sulawesi. The method used was Snorkeling Visual Census (SVC). The results obtained indicate napoleon fish abundance is low (0 to 4 individuals/ha). Highest abundance of napoleon fish was found in Lapoipoi & Batanglampe, however none in three locations, i.e., Larearea, Pasiloange and Malambere. It is suggested that protection to species & its habitat is done in four locations where the napoleon fish were found, especially in Lapoipoi & Batanglampe.

Humphead wrasse (Cheilinus undulatus), also called napoleon fish or “katepas “ in Anambas Archipe... more Humphead wrasse (Cheilinus undulatus), also called napoleon fish or “katepas “ in Anambas Archipelago Regency, Indonesia, is a reef fish which commonly found in tropical seas. Napoleon fish exploitation is still getting higher especially in Indonesia. Nevertheless, this species had listed as a protected species by the Indonesian Government as well as enlisted in Appendix II of CITES (Convention on International Trade in Endangered Species). Following a dialog among Indonesian officials, FAO and CITES, quota permission has been given to the fisherman community of Anambas Regency. This permission was legally allowed the Anambas Fishermen to fishing the napoleon fish juveniles and reared them in floating net cages for 3-4 years to reach commercial size. About 147,000 napoleon fish were estimated to be reared in Anambas Island. The first export of Napoleon fish was recorded in 2018 by one of the Indonesian fish exporters from Anambas to Hong Kong with 1,000 fish or Rp 1 billion worth and equivalent to $ USD 71.4/kg. The aim of this research was to analyse spatial distribution, juveniles abundance and water quality of the Anambas Islands to improve the sustainability of napoleon fish juveniles resources. Juveniles and water quality data were collected during field survey in 2014 and 2015. The abundance of the juvenile was estimated from monthly data recording by fishermen and water samples were measured in-situ. Post to the measurement of the physical and chemical properties, water quality was determined by using the National Sanitation Foundation Water Quality Index (NSF-WQI) based on The Classification of the Index numerical values. The results showed that napoleon fish juveniles were concentrated in several specific locations around Anambas waters. The highest abundance of napoleon fish juvenile was observed in November and December. The waters quality indexes show good and very good conditions for culturing the juvenile in floating net cages. The success in napoleon fish juvenile rearing is a starting point to achieve the fish sustainable aquaculture-based fisheries management. This research concludes that the identified natural rearing areas of juvenile napoleon fish, good water conditions, and improved existing rearing technology might support sustainable ranching-based aquaculture of humphead wrasse in Anambas Islands waters.

Runtuboi et al. (2018) explained that the condition of coral reefs determines reef fish composition and diversity. In the coral reef ecosystem, reef fishes are the most abundant organisms (Nybakken 1982). The high diversity of reef fishes impacts various and complex habitats in the coral reef ecosystem. Therefore, the reef fish diversity is an important indicator of the health level of coral reef ecosystems (Adrim et al. 2012; Hourigan et al. 1988). Bell and Galzin (1984) also explained that changes in the diversity of reef fish communities could indicate changes in the ecosystem. Coral reef ecosystems positively correlate with reef fish diversity (Bengen 2013; Marshel and Mumby 2015). Besides playing an essential role as an environmental health indicator, the existence of reef fish is also a source of livelihood for the community living on the coast and small islands. Reef fish diversity will help accumulate more ecological service capital (eco-service capital) and is also used to evaluate the various impacts of human activities on ecosystem function (Eduardo et al. 2018; Palumbi et al. 2009; Paulangan et al. 2019). Reef fish is one of the aquatic organisms that correlates significantly in the coral reef ecosystem. There is an excellent coral reef ecosystem that can increase reef fish production. The primary function of the coral reef ecosystem for the reef life is as a spawning ground, nursery ground, and feeding ground. Smith (1978) and Rondonuwu et al. (2019) revealed that one describing the complexity of coral reef habitat structure is the abundance of individual coral reef fish. The research results in North Minahasa illustrate that the complexity of the coral reef habitat in Likupang Village, and Ambong ABSTRACT Reef composition and diversity of coral reef fishes play an essential role in the ecosystem. The reef fish diversity is a crucial indicator of the health level of coral reef ecosystems. The benefit of fish diversity in coral reef ecosystems is to describe ecological services. This research intended to determine reef fish diversity among stations at different depths, consisting of shallow water and reef slope. Research sampling was done in July 2018 and July 2019 in Tunda Island waters at eight stations billowing the coral distribution pattern. Collected data of reef fishes were by using Underwater Visual Census (UVC) on Belt Transects Method at 250 m 2 transect area (50 meters of length and 2.5 m on either side). The result showed 69 reef fishes in shallow water and 67 species on the reef slope. The total of fish species ware from 13 families consisting of Acanthuridae,

Contoh kepiting diambil secara acak dari hasil tangkapan bubu. Data sebaran frekuensi lebar karapas dikumpulkan selama sebelas bulan pengamatan. Analisis data parameter populasi dilakukan dengan bantuan software FISAT (FAO-ICLARM Stock Assessment Tools). Hasil analisis menunjukkan terdapat beberapa kelompok umur/ukuran kepiting bakau. Lebar karapas asimptotik populasi kepiting bakau mencapai 147 mm dengan koefisien pertumbuhan tahunan (K) 0,59. Laju eksploitasi kepiting bakau (E = 0,4) masih di bawah laju eksploitasi optimum. Hasil tangkapan kepiting bakau mencapai 23,8 ton per tahun. Hasil pengukuran di lapangan menunjukkan bahwa 70% berupa kepiting muda (nama lokal "keroyo"). Kondisi ini (growth over fishing) akan semakin mengkhawatirkan jika penangkapan berlangsung terus. Kondisi lingkungan perairan di sekitar mangrove dan perairan pantai cukup menunjang kehidupan biota termasuk larva kepiting bakau dan larva biota lain.

The Pari Island cluster has potential ecosystems, such as coral reefs, seagrass, and mangrove. The presentation of this article is an overview of the results of research conducted by the Research Institute for Marine Fisheries and the Research Institute for Fisheries Enhancement, The Agency for Marine and Fisheries Research and Human Resources. This study aims to present and describe habitat and reef fish populations. The assessment result shows that the criteria for the coral reefs’ health were poor to good, mostly moderate, the best in the southeast and northeast waters, which had been designated MPAs. Reef fish population density on the criteria was very rare or low at all observation sites. The dominant group was Caesio cuning, Cephalopholis boenak, Scarus ghobban (target group), and Chaetodon octofasciatus (indicator group). The implementation hopes Pari Island Cluster waters would expand to be designated MPAs due to the large number of care areas used for fishing territories.

Moreover, seasonal observation of water quality and phytoplankton has yet to be assessed. This study aimed to determine the control of seasonal water quality and nutrients over phytoplankton abundance throughout the East Aceh coast. Direct field measurements and laboratory analyses were performed to collect the primary data, whereby the sampling period was conducted during the displacement toward the ebb tide. We assessed the water quality parameters using a modified CWQI (coastal water quality index). Furthermore, linear regression and principal component analysis were performed as the basis of statistical analyses. The phytoplankton abundance was higher in April than in September, with most Bacillariophyceae and Dinophyceae in all observed stations. Except for DO and turbidity, the assessed water quality parameters (temperature, TDS, conductivity, salinity, sulfide, and TOM) are feasible for marine biota. Of particular concern, the East Aceh coast is characterized by poor-good water quality, with the CWQI value ranging from 40 to 90. Based on the regression and PCA analyses, N and P nutrients significantly control the phytoplankton abundance like a "seesaw" between April and September, with a respective coefficient determination of about 50%. Because of the tremendously high phosphate observed in April, the water condition tended to be P-limited and vice versa for September. On the other hand, instead of evoking the phytoplankton growth, each water quality parameter has a specific influence in characterizing phytoplankton communities in the study area.
