Abstract

Preliminary surveys for coral disease were conducted in October 2011 as part of the first Indonesian coral health workshop in Barranglompo Island, part of the Spermonde Islands, South Sulawesi, Indonesia. Previous coral disease surveys conducted in Wakatobi National Park (WNP), South-East Sulawesi in 2005 and 2007, and qualitative surveys in April 2011, are included here to provide an overview of what is known about coral disease in Sulawesi and to compare results with reports from other regions of the world. On all reefs surveyed in these two locations, levels of coral disease were relatively low compared with global averages from other locations. In preliminary surveys of Spermonde reefs, the most significant syndrome detected was white syndromes, which affected 13 different coral genera. The most significant syndromes detected in WNP were white syndromes, black band disease, and a yellow tissue discoloration syndrome that was similar macroscopically to Caribbean yellow band disease. Although overall coral disease prevalence was low in Barranglompo and WNP, there is the potential for greater impacts of coral disease as anthropogenic influences increase and the oceans continue to warm. This study provides preliminary baseline data on the impact of coral disease within the reefs of Sulawesi, Indonesia, the center of coral reef biodiversity.

Abstract

Fertilization and larval development determine the coral population survivalof species, which has adifference characteristic of embryogenesis. This research wasaimed to compare the embryo and larvaldevelopment spawned in November 2011 in Grear Barrier Reef, Australia.Embryonic cellsdevelopment wereobserved in interval timesfrom one cell of egg tomulticellular stage (prawnchip), and larval developmentobserved from the prawnchip stageto the planulae.The results showed the development of embryos and larvaesignificantly differed between two species, i.e. embryos and larvae of Acropora millepora grew faster thanA.tenuis. The maximum size of planulae larvae of A. millepora (800-1000 μm) is biggerthan A. tenuis (650-900μm). Embryo and larvae development were different due to species variability, hence this reseach can beadapted for laboratory proccess of coral larvae nursery. Keywords: embryo, planulae, Acropora millepora, A. Tenuis

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

Bed sediment characteristics and distribution is one of the important parameters in determining the management plan and utilization of estuarine and coastal waters.  The objective of this study was to analyze sediment distribution and determine dominant oceanographic factors controlling the distribution of bed sediment in the river estuary and coastal sea of Malili. Sediment samples were collected using a grab sampler at ten stations, namely four stations in the river estuary and six stations in the adjacent coastal sea for grain size and sediment organic content analysis. The results showed that the bed sediment along the river estuary consisted of silt, very fine sand, fine sand, and medium sand with organic content varying from 1.31 to 7.18 %. In the coastal sea, bed sediment was dominated by silt with a higher organic content of 2.25 - 7.31%

Abstract

The Spermonde Islands are part of the mega diversity area in the world's coral triangle area, crossed by the Wallace line. The Spermonde Archipelago consists of 120 islands spread over four zones: the inner zone, middle inner zone, middle outer zone, and outer zone. Samalona Island is located in an inner zone with a high level of eutrophication, and Langkai Island is located in an outer zone with a high brightness level. This study aims to determine whether there are differences in zooxanthellae density in various life forms and coral reef zones in the inner and outer zones of the Spermonde Islands. Coral sampling was done at coral reef ecosystems on Samalona Island and Langkai Island using SCUBA tools, cutting tools, and plastic samples. The zooxanthellae were separated from their hosts using a modified airbrush sprayer with an air pressure of 3000 psi. The zooxanthellae density was calculated using the formula of Eaton et al. Water qualities were measured in-situ using the water quality checker. The data were analyzed using factorial analysis with two factors. This study indicates that the zooxanthellae density in the folios life form is higher than in the encrusting and branching life forms. This study indicates that: (1) the zooxanthellae density in the same life form is not significantly different between the inner zone and outer zone; (2) the comparison of the zooxanthellae density in the same coral reef zone was not significantly different between the inner and outer zones; (3) the comparison of zooxanthellae density in the same coral reef zone was significantly different between life forms in the inner zone (Samalona Island); (4) the comparison of the zooxanthellae density in the same coral reef zone was significantly different between the life forms in the outer zone (Langkai Island).

Abstract

Jellyfish can be found in most coastal waters and their occurrence can be frequent during the day. This study aimed to detect the occurrence of jellyfish based on the oceanographic condition in the coastal waters of Makassar. Observations were conducted in July-September 2018 at three stations namely Port of Soekarno Hatta (Station 1), Port of Paotere (Station 2), and Port of Untia (Station 3). Jellyfish sampling was conducted in the morning, noon and afternoon, from three stations as aforementioned. Jellyfish samples were taken and identified at the Laboratory of Marine Biology, Faculty of Marine Science and Fisheries, Universitas Hasanuddin. Oceanographic conditions, i.e. temperature, salinity, transparency, and current velocity, were measured. All data were analyzed descriptively. It showed that the oceanographical conditions were in the suitable range for supporting jellyfish growth. Three genera of jellyfish were found, namely Aurelia, Porpita, and Aequorea. Aurelia was abundant in Station 1 and 2, whereas Porpita in Station 3. It also showed that during the afternoon, the jellyfish occurred more frequently.

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.

Abstract

Coral spawning occurs throughout the year in Indonesia due to tropical climate conditions that influence coral development and spawning. As representative data on coral gonad development in the Spermonde Archipelago, observations on the development of the Faviidae gonads were conducted on Barrang Lompo, Kodingareng Keke, Samalona, and Bonetambung Island. Environmental elements are measured in the form of surface water temperature and rainfall. Based on the abundance of this type of gigantic coral at the study site, coral tissue sampling was concentrated on the Faviidae. The pigmentation of the gonads of Faviidae has been studied visually in nature. The samples were carved on the coral before being photographed. To make it easier to detect the level of pigmentation in each species, coral gonadal tissue was imaged. If there is an orange, yellow, or blue tint, it indicates that the coral has colored gonads and is mature gonads, indicating that coral spawning will occur soon. A water lever logger was used to measure the temperature of the water. The results of water temperature measurements vary and can be linked to the development of coral pigmentation as well as observations from November to March when the third phase (pigmented) process in Faviidae was considered to have happened in large numbers. It is possible that Faviidae can breed during this sensitive period. Rainfall data was gathered from Makassar City's Paotere Maritime Meteorological Station.
