Abstract

Pelagic fish are spesies that live in water column at depth of 100 to 200 meters from surface. They migrate as a group looking for nutrient and spawning place. Potential fisheries comodities in Indonesia including pelagic fish have high economic value. Then, stock assessment of pelagic fish measurement is important to researched. The research was conducted in May – June 2016 surrounding South China Sea waters using Madidihang 02 Research Vessel operated by Marine Fisheries Affair (MFA) Republic of Indonesia. To estimate the density of pelagic fish hydro-accoustic equipment and oceanography parameters were used and measured during the campaign. The split beam echosounder was use in aim to obtain precission position and number of fish target. The highest density of fish was found around Tambelan Island and Anambas Island. Statistically pelagic fish density has correlation with chlorophyll-a, salinity, temperature, and sea current velocity. The statistical analysis between pelagic fish density and those oceanography parameters (as statistic variables) yields positive vector correlation.

Abstract

This research aims to understand the condition of coral reef (life coral), the abundance of reef target fishes, and the corellation between those two variables. This research has been conducted in Tinabo Besar Island with 6 sampling stations in 5-6 meter depth. Data collected are substrate cover precentage (life form), and the number of reef target fish appeared from 7 specified families (Serranidae, Lutjanidae, Haemulidae, Lethrinidae, Scaridae, Siganidae, and Acanthuridae) using Underwater Photo Transect (UPT) and Underwater Visual Census (UVC). Substrate cover analyzed using CPCe software with life coral, dead coral, algae, abiotic, and other biota cover output. Mortality Index (MI) obtained from the ratio of life coral and dead coral. The result shows that percentage of life coral coverlie between 11.87% to 38.80%, with dominance of Coral Masive (CM). It’s mean that the coral reef condition is in poor to moderate category. Coral death ratio is low with MI between 0.15 to 0.30. Reef target fish total abundance is 493 individual/2100m2 from 31 species, with dominance from Lutjanidae family (173 individual). The result shows positive and strong enough correlation between coral reef coverage and reef target fish abundance (r=0.65) with Determinantion Coefficient at 42.55%. Linear regression is y=-12.929+3.7562x, where in every addition of coral reef cover percentage, resulted in addition of 4 fishes.Keyword: life coral, abundance, reef target fish, correlation, Tinabo Besar Island

Abstract

Dugong is the only herbivory mammals in the sea and mainly feed on seagrasses. Population of dugong tends to decrease in all ofits range as an impact from hunting, fishing activities and habitat degradation. In South Sulawesi-Indonesia, recent informationabout dugong population is unknown due to limited observation. Last dugong existence reported from Barranglompo Island in1991. This research aim to reveal the existence of dugong in Spermonde Archipelago. Result of this study showed from 1992to 2017, only 6 individu of dugong were observed. In 2006, one live dugong accidentally found roaming near Samalona Island.This encounter was successfully recorded by video camera. Four years later, one dead dugong found trapped in fishing net nearLantangpeo village, Tanakeke Island and sold to local fishermen for consumed. In 2014, one dugong grazing track was alsofound in Tanakeke Island near Balandatu Village. Information from 2016, reported two dugongs in seagrass meadow aroundPuntondo and Laikang Bay. Last report on 31 January 2017, showedone decomposed body from young dugong stranded inBarranglompo Island. The death cause remaining unknown. From interview with some witnesses and local fishermen, dugongaccidentaly found trapped, drown and dead in fishing net that set up around seagrass meadow. Captured dugong will on sale andslaughtered for its meat.With only once encountered alive in 25 years (which recorded by video camera), it can be concludedthat dugong population in Spermonde archipelago were extremely rare, heavily threatened and facing extinction.Keywords: dugong, sighting, Spermonde Archipelago, South Sulawesi

Abstract

The high level of human activity in coastal areas has had an impact on seagrass beds. The advancement of satellite imaging technology makes monitoring seaweed conditions even easier. The purpose of this study was to identify the spectral reflectance patterns of different seagrass cover levels and make it the basis for mapping the seagrass condition on Barranglompo Island. Based on google earth has been determined 4 sampling stations that represent the spread of seagrass on Barranglompo Island. Each station is divided into 4 sub-stations from land to sea. Sampling of seagrass cover was carried out by the McKenzie (2003) method modified by close sampling, to 30 x 30 square meters following the spatial resolution of Landsat image 8. Each observation point was estimated the percentage of seagrass cover and the dominant species. Digital seagrass pixel extraction is performed from band 1 to 7 landsat 8 according to point position in the field and then grouped by cover class and condition. Seagrasses found in Barranglampo Island are 8 species: Enhalus acoroides, Thalassia hemprichii, Halophila ovalis, Cymodocea rotundata, Cymodocea serulata, Halodule uninervis, Halodule pinifolia and Syringodium isoetifolium. In general, Enhalus acoroides and Thalassia hemprichii have higher closure than other seagrass species. The spectral reflection of seagrass landscape imagery 8 OLI channel 1 - 7 is good enough to show the seagrass condition in bad category, good enough, and good. Spectral reflection of the seagrass has a peak on the green channel. The worse the seagrass condition the higher the spectral reflection. Seagrass with bad conditions has a low cover so that other substrates such as sand will contribute to the spectral value recorded by satellite sensors. This result will facilitate mapping of seagrass condition on small islands by using Landsat 8 OLI image.Keywords: seagrass condition, spectral reflection, landsat 8, South Sulawesi

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

Coral reefs and seagrass are natural fortress for small islands from waves and ocean currents. The spatial distribution of these benthic substrate should be known and monitored regularly. This study aims were to map existing benthic substrates on the reef flat of Bontosua Island, determine the spatial composition and develop index ratio. Benthic substrates were surveyed using geotagging technique. Their distribution were estimate using Quickbird image that was rectified and classified using ISOcluster method and validate by 240 selected photos. The seagrass were surveyed at 8 stasions to record percent cover and species composition. Depth profiles were track along 10 reef flat line segment. Bontosua Island has an elongated shape from South to Northwest. This study had produced a benthic substrate distribution map with thematic accuracy 76%. Total area able to map were 54.2 hectares. About 43% benthic substrates at Bontosua were mixture of coral rubble, seagrass and algae, 20% was mixture of rubble and algae, 16% dominated by seagrass, 13% mixture of sand and seagrass and 8% substrate were dominated by live coral. There were eight seagrass species found with average percent cover 37.2 ± 12.5 percent. The spatial ratio of live coral, seagrass and mixed substrate for West side reef flat was 2:20:49 and 1:9:9 for East side. This indicate that the distribution of benthic substrates on the West side is much wider than on the East side. This approach potentially applied to study the relationship between benthic substrate composition and the deformation of small islands.

Abstract

Some upper air atmospheric parameters measured during period of 2011-2016 by means of radiosonde located at Hasanuddin International Airport were examined for characterization of boundary layer over Makassar, Indonesia. These data, combined with surface atmospheric parameters were used to calculate some boundary layer parameters using AERMET model which based on Monin-Obukhov similarity theory. The obtained Monin-Obukhov length which reflecting atmospheric stability then converted into traditional Pasquill-Gifford stability classification. Examination of wind characteristics of wind showing clearly their dependence of the day, season and height. Winds dominantly flows from the southeast during the daytime with the relatively larger velocity and from the northwest with smaller velocity during the nighttime. Interpretation of monin-obukhov length using Pasquill-Gifford stability classification showing that the atmosphere was dominantly unstable during the daytime and dominantly stable during the nighttime. These atmospheric stabilities were also varied during seasons. The height of convective boundary layer (CBL) was start to rise in the morning and reaching its maximum in the afternoon (18:00) at the mean value of 2 km. Meanwhile, the height of mechanical boundary layer (MBL) during the day time forming parabolic curve with its maximum value of 1.2 km at noon. These indicated that any released pollution from the stack will be less dispersed during the nighttime due to the fact of lower mixing height, lower wind speed, atmosphere become more stable, and it dispersed in different direction compare to the daytime.
