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. Penelitian ini menggunakan metode survey. Data yang dikumpulkan adalah kelimpahan ikan Chaetodontidae (Jumlah spesies dan individu dengan menggunakan teknik sensus visual). Jumlah ikan karang famili Chaetodontidae yang di temukan di Daerah Perlindungan Laut Desa Bahoi berjumlah 20 spesies, dengan jumlah individu pada kedalaman 3 meter dan 10 meter berjumlah (56,66 individu/150m2 dan 57,33/150m2 individu).

Vibrio Coralliilyticus

Bleaching and disease are decimating coral reefs especially when warming promotes bleaching pathogens, such as Vibrio coralliilyticus. We demonstrate that sterilized washes from three common corals suppress V. coralliilyticus but that this defense is compromised when assays are run at higher temperatures. For a coral within the ecologically critical genus Acropora, inhibition was 75 to 154% greater among colonies from coral-dominated marine protected areas versus adjacent fished areas that were macroalgae-dominated. Acropora microbiomes were more variable within fished areas, suggesting that reef degradation may also perturb coral microbial communities. Defenses of a robust poritid coral and a weedy pocilloporid coral were not affected by reef degradation, and microbiomes were unaltered for these species. For some ecologically critical, but bleaching-susceptible, corals such as Acropora, local management to improve reef state may bolster coral resistance to global change, such as bacteria-induced coral bleaching during warming events.

Reef Ecosystem

Conservation effort and knowledge on coral reef ecosystem are necessary to protect marine ecosystem. Coral reef ecosystem is very important to support marine biota especially fishes and benthos. The presence of coral reef indirectly support local people income, therefore is is necessary to conserve coral reef ecosystem. District of South Waigeo is one of tourist area as well as preserve area in Raja Ampat Regency of Papua Barat Province. The aim of this study is to identify the current condition of coral reef in Saporken Village of South waigeo District. Data were collected by survey method using coral reefs Point intercept transect method, observation and interviews to determine the social, economic and cultural impact., and measures taken to manage coral reef management in village Saporkren Marine Protected Areas. The results showed that knowledge Saporkren Village community, the conservation community knows about how destructive such arrests are not carried out the bombing, while the traditional way people work is local wisdom. Condition of coral cover in the village of Marine Protected Areas Saporkren in good condition (live coral cover=51%) and very good water quality, flow velocity at high tide ranged from 4.25 to 22.3 cm/sec and the flow velocity at low tide over small ranging from 5.07 to 19.60 cm/sec, salinity ranged from 32–35‰ and wave height ranged from 0.75 m. Based on the results of this study concluded that: Village community know Saporkren conservation activities of local government programs, and the traditional way to preserve coral reef still implemented.Key words: Conservation, coral reefs, Saporkren village, Raja Ampat.
