Reef Condition

The coral reefs are a sundry of marine life. Which one is reef fish in family Chaetodontidae. This fish is  indicator of the coral reef condition. The aim from the research is : discover of spatial distribution of the reef fish family Chaetodontidae and find out of the intercourse of reef fish family Chaetodontidae with the coral reef presence based on growth of coral form. The research was do in the coral reef at Marine Protected Areas in Bahoi Village District of West Likupang North Minahasa Regency, on Tuesday, December 23rd, 2014. The research is using to do the surveying method. The data is collecting distribution of the fish Chaetodontidae (amount from species and individuals to using by technic visual census). The total of reef fish family Chaetodontidae those found in Marina Protected Areas in Bahoi Village is about 20 species, with total of the individuals at a depth of 3 meters and 10 meters is (56,66 and 57,33 individuals/150m2). Keywords : Coral reefs, Chaetodontidae, Bahoi   ABSTRAK Terumbu karang merupakan tempat berbagai macam biota laut. Salah satu Ikan karang adalah ikan famili Chaetodontidae. Ikan ini merupakan ikan indikator terumbu karang. Tujuan dari penelitian ini : mengetahui kelimpahan dari ikan karang famili Chaetodontidae. Penelitian ini dilakukan di Daerah Perlindungan Laut Desa Bahoi Kecamatan Likupang Barat Kabupaten Minahasa Utara, pada hari selasa, tanggal 23 Desember 2014.

Protection Cost

Fisheries managers in the United States are required to identify and mitigate the adverse impacts of fishing activity on essential fish habitat (EFH). There are additional concerns that the viability of sessile noncommercial species, animals that are habitat dependent and (or) are themselves constituents of fishery habitat, may be threatened by fishing activities. We propose a system of individual habitat quotas (IHQ) to achieve habitat conservation and species protection cost effectively. Individual quotas of habitat impact units would be distributed to fishers with an aggregate quota set to maintain a target habitat "stock". Using a dynamic, spatially explicit fishery simulation model, we explore the efficiency and effectiveness of an IHQ policy versus marine protected areas (MPAs) for conserving habitat-dependent, sessile species of unknown spatial distributions. Our findings indicate that an IHQ policy with a conservatively established habitat target is better suited to the protection of sessile nontarget species than a rotating or fixed MPA policy.

Abstract. The study was conducted onApril to October 2013 in marine protected areas of Weh Island. The samplings were done at10 siteswhere 6 sitesare situatedinside of conservation areas, while 4 sites are situated outside of conservation areas. The purpose ofthis study was to evaluate coral covers andreef fish composition. Point intersept transect(PIT), underwater visual census (UVC) and fish catches were used to examine coral covers, abudance and biomass of reef fish. The results showed that average of coral covers, abudance and biomass of target fishes inside conservation were 54%, 1,662 ind/ha and 408.78 kh/ha, respectively, while than outside conservation was 33.05%, 1,058 ind/ha and 307.77 kg/ha, respectively. Total of reef fish species and the catch were increased from previous years, for example there are 60 species in 2010 and it was increased to 83 species in 2013. In addition the fishermen catches were increased slightly from 3.03 kg/trip in 2008 to 3.6 kg/trip in 2013. It is concluded that the coral condition and reef fish composition in the conservation are much better compared to outside of conservation areas.Keywords : Marine protect area; reef fish; Weh Island Abstrak. Penelitian ini dilakukan pada April sampai Oktober 2013 di Kawasan Konservasi Perairan Pesisir Timur Pulau Weh yang terdiri dari 10 stasiun dimana 6 stasiun berada didalam kawasan konservasi dan 4 stasiun diluar kawasan konservasi.Penelitian ini bertujuan untuk menilai persentase tutupan karang dan komposisi ikan karang. Sampling menggunakan transek titik dan underwater visual sensus (UVC) dan hasil tangkapan.Hasil penelitian menunjukkan bahwa rata-rata kondisi tutupan karang, kelimpahan dan biomassa ikan target dikawasan konservasi yaitu 54%, 1.662 ind/ha dan 408,78 kg/ha, secara berurutan, sedangkan diluar kawasan konservasi adalah 33,05%, 1.058 ind/ha dan 307,77 kg/ha biomassa ikan target.Jumlah jenis ikan karang di kawasan konservasi meningkat, yaitu 60 jenis tahun 2010 menjadi 83 jenis pada tahun 2013 dan rata-rata hasil tangkapan tahun 2008 yaitu 3,03 kg/trip dan tahun 2013 yaitu 3,6 kg/trip. Dapat disimpulkan bahwa kondisi karang dan komposisi jenis dan ukuran ikan lebih baik di dalam kawasan konservasi berbanding diluar kawasan.Kata kunci: Kawasan Konservasi; Ikan karang; Pulau Weh
