Abstract

 Coral disease is one of the threats to the health of coral but is not yet widely known. This study was conducted todetermine the types of bacterial associations in hard corals infected with growth anomaly (GA). Coral samplesinfected with GA disease were taken by using SCUBA tool on Salemo Island, Mattiro Bombang Village, PangkepDistrict. Bacterial isolation was performed by removing mucus from corals infected by growth anomaly by 1ml and diluted to dilution 10-3 . Purification of bacteria is done by inoculating the solid medium of Marine Agar.Furthermore, Gram staining and biochemical tests were performed. Bacterial identification was performed basedon colony morphology and biochemical reaction test results. The results showed that GA disease can infectcoral Porites, Acropora digitate, Platygyra and pocillopora . Bacteria are found from the genus Flavobacterium,Acinetobacter  and, Neiseria. Keywords: Bacteria association, coral stone, coral disease, growth anomaly

Abstract

The purpose of this study was to analyze the succesfullnes use of two coral reef transplantation methods in the rehabilitation ofcoral reefs damaged by the phenomenon of bleaching in 2016 at the waters of Liukangloe Island, Bulukumba, South Sulawesi.In this study two methods were implemented, i.e. methods frame-spider and methods of nails-natural substrates, with 5 unitsas replication, respectively. A total of three kinds of branching corals weretransplanted, namely Acropora robusta, Poritescylindrica, and Pocillopora verrucosa. On each unit transplantation models, attached 6 coral fragments with branch length of5-12 cm for each kind of corals. A total of 3 fragments for each species of corals were labeled and coded for the survival rateand absolute growth monitoring. All five unit of experiments on each model are placed on two areas separately and placedrandomly with depths ranging from 3-4 m in the northern part of island. Observations survival rate and absolute growth of coraltransplant were conducted for every 2 weeks for 28 days by counting the dead coral fragment or missing and measure the lengthof transplant coral branch with a measuring ruler. The effectiveness of the two methods was analyzed based on the survival andgrowth of the absolute value of coral transplant. Survival rate were analyzed descriptively and the average values of absolutegrowth were analyzed by t-student. The use of frame-spider methods and methods of nails-natural substrates as effective inrehabilitating the coral reefs from bleaching phenomenon based on the parameters of survival and growth of Acropora robusta,Porites cylindrica, and Pocillopora verrucosaKeywords: Transplantation methods, coral reef, bleaching coral, Liukang Loe Island

Abstract

Climate change and global warming cause massive damage to the environment. One of the major events that arethreatening the marine ecosystem is coral bleaching. Coral bleaching occurs when corals are exposed to above or belownormal temperatures. The aims of this study are to compare the resistance of Isopora palifera and Acropora hyacinthusfrom Karanrang Island to temperature stress. Four treatment temperatures (28ºC, 30ºC, 32ºC, and 34ºC) were tested toassess the role of temperature stress and bleaching to Isopora palifera and Acropora hyacinthus for 48-hours. Theabundance of zooxanthellae counted as the temperature stress variable. The results showed that there was a difference ofcoral response tothe treatment based on the time of experiment, after 48-hours experimentexposed at temperaturetreatment of 34°C the abundance of zooxanthellae from Isopora paliferawas 0,06 x105 cm-2 and the abundance ofzooxanthellae from Acropora hyacinthus is 0,18 x105cm-2. In comparison between species, Isoporapalifera taken fromKaranrang Island was more resistant to temperature stress thanAcroporahyacinthus.

Abstract

Spermonde and Sembilan Islands (Bone Bay) are the central distribution of coral reefs in South Sulawesi. These archipelagos are likely to be at risk from eutrophication and sedimentation from intensive agriculture and aquaculture activities, in particular through transport of nutrients and materials discharged to the river systems on the Sulawesi mainland. The aim of this study was to analyse the temporal dynamics of eutrophication levels and sedimentation rates on coral reefs area of Spermonde and Sembilan Islands. Nutrient concentration and sedimentation rate were collected at monthly intervals over 4 months, at six stations: three in the Spermonde Islands (Laiya, Kodingareng, and Samalona Islands), and three in the Sembilan Islands, Sinjai District (Batanglampe, Kambuno, and Burungloe Islands), with two data collection points/replicates at each station/island. The results showed that phosphate concentration and sedimentation rates were higher in the Sembilan Islands, whereas nitrate concentrations were similar in both island groups. Nitrate concentration data indicated that eutrophication levels was varied, ranging from oligotrophic to eutrophic conditions, depends on months. In July and September, eutrophication was observed at all stations in both locations. Sedimentation rates were higher in the Sembilan Islands, but declined gradually until the end of the study time. Conversely, at stations in the Spermonde Islands, especially Samalona and Kodingarengkeke Islands, sedimentation level was increased significantly until the end of the study.

Abstract

Marginal coral reefs are located in a limited aquatic environment, causing coral organisms to live under threat and only certain species of coral are able to survive. Porites lutea is one species of coral that is able to live in normal and marginal coral reef conditions. The purpose of this study is to determine the ecology of Porites lutea, the physiological ability of Porites lutea's Productivity (P) and Respiration (R), coral reef habitat conditions and environmental factors that affect the distribution of Porites luteal in normal and marginal locations. This study used the belt transect method, measurement of coral colony volume, physiological productivity (P) and respiration (R), transect picture for substrate cover and coral reef conditions and CTD to measure environmental indicators such as temperature, salinity, turbidity, chlorophyll and DO. The results shows that the density of Porites coral is higher at normal coral reef locations (Pak Kasim), the highest volume range is 25-100 cm3, with the largest size in the 451-475 cm3 class. P/R values ​​is higher at normal coral reef sites, especially in reef slope areas. Coral reef habitat cover is dominated by abiotic components with poor coral reef conditions in marginal and normal environments. Water temperature was significantly different (P=0.039) between two normal and marginal locations with a range of 27.08 - 27.51 oC, Salinity was significantly different (P=0.145) with a salinity 33.44ppt at normal locations and 32.88 ppt at marginal locations. The chlorophyll and oxygen number was not significantly different between the two locations, the range of chlorophyll 0.03 – 0.15 mg/L and oxygen 2.49 – 5.23 mg/L. The turbidity factor was significantly different between locations (P=4.86E-07) where the marginal location in Sample was more turbid than the normal location in Pak Kasim. This study shows that there are differences between normal and marginal waters in environmental conditions and physiological reactions of Porites lutea, but this coral is able to survive to show their resilience to environmental stresses.  Keywords: Coral physio-ecology, Porites lutea, P/R ratio, marginal coral reefs.
