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.

Survival And Growth

More than 20,300 fragment corals belonging to 24 species, eight genera and six families were rehabilitated in marine protected areas of south Vietnam. Mean survival rates of coral fragments ranged from 60–97.7%, the average growth rate of the branched corals was 4.8 mm/month meanwhile the foliose coral was 1.9 mm/month. The survival and growth rate of corals are different among areas because each coral species has different biological characteristics, structure colonies and due to differences in natural conditions each area. The results showed that the growth rate of corals will return to normal after 4 months rehabilitation. The factors affected the effective coral rehabilitation including: Coral reef predators, spatial competition among species, environmental conditions change due to human’s activities; and other factors such as hydrodynamic regimes, cutting fragment corals cause its injury damage. The rehabilitation and protection activities of coral reefs in marine protected areas should be continued and expanded, contributing to the protection of biodivesity, marine resource and sustainable coral reefs ecosystem development.

Northern Red Sea

Holothuroid sea cucumbers are vital members of Coral Reefs and associated marine habitats and provide vital ecological services. In the southern regions of the Red Sea their populations have been decimated by overfishing. The main objective of this study was to test the hypothesis that the northern part of the Red Sea serves as an ecological refuge for the species threatened farther to the south. Accordingly, populations of sea cucumbers in 4 shallow sites south of Eilat, Israel (29°33′00N 34°57′14E), were repeatedly surveyed from November 2013 to April 2014. Overall 11 species were observed in these shallow sites. Their abundance and diversity differed significantly between sites, but not temporally. In sites in marine protected areas, with an intact fringing reef, diversity was high, withHolothuria edulisandBohadschiasp. being the most common species. In areas with higher human use and characterized by rubble and scattered corals, diversity was low, andActinopyga bannwarthiwas the most common species. The observed abundance and diversity did not support the refuge hypothesis. These findings are discussed in relation to other surveys of abundance and diversity in similar habitats.
