Abstract

Large pelagic species such as tuna are known to be abundant in Mamuju Waters,  Makassar Strait.  The distribution and abundance of the fish in that area are expected to be  related to the distributions of sea surface temperature and chlorophyll-a concentration. This study aims to predict spatial and temporal distribution of the species during the period of June 2013-May 2014.  Probability indices used for detection of tuna potential fishing zones (PFZs) were constructed from a model of satellite-based SST and chlorophyll data in relation to tuna fishery. Results showed that the occurrence of tuna species in Mamuju Water were mostly predicted in areas of 118°12’-118°48’ E 1°48’ – 2°30’S with the total area of approximately 7,495 km2.   The potential fishing zones were mainly found in August.  It was likely that tuna potential fishing zones associated with the preferred oceanographic factors throughout the study area.

Abstract

The study, in 2012, has successfully formulated with the MCDM for each allocation of  space in KKPD allotment (core areas, sustainable fisheries zone, used zone, and other zones). This weighting techniques need to be tested and  be implemented in identifying and designing the KKPD in the study area. This study aims to identify and map the biophysical conditions and the potential of coastal and marine natural resources in marine conservation area candidate, North Luwu Regency; to identify the areas suitable for the KKPD based on weighting technique with the MCDM method; and to evaluate potential candidates for marine protected areas in the coastal region. This study used a survey method to perform in  situ measurements of physico-chemical parameters, conducted a survey of coastal ecosystems using the transect method. The socio-economic data of coastal communities were collected using the questionnaire. The biophysical conditions and marine resources were analyzed using descriptive statistical methods. The results showed that the candidate region has a rich diversity  of coastal ecosystems, but the ecosystem, particularly seagrass beds and coral reefs have been in damaged category. Only the mangrove ecosystem that was still in a good condition category with moderate-to-heavy levels of density. There were 6 species of seagrasses and 6 species of mangroves and 71 species of reef fish. It was discovered 2 regions  corresponding to the allotment of the Core Zone, which is in the Region I and III with the total area of 654.22 hectares. For sustainable fisheries zone, Region  II and IV would be the first choice with the total area of 620.27 hectares. The Used Zone was identified in the Region V with total area of 480.66 hectares. The total area of the region was equal to 1755.15 hectares. Marine protected areas of was suggested to the protection of coastal ecosystems including mangroves, seagrass beds, and coral reefs and its associated biota, especially the protection of local feeding ground of several species (sea turtles and dugongs).

Abstract

Culture of ornamental corals applying transplantation technique was aimed to know the successful of this transplantation technique in the ornamental coral culture based on its growth and survival rate of various coral fragments. The location of the medium settlement was in the western side of the waters of Tonyaman Village, Binuang Subdistrict, Polewali Mandar Regency with 3-4 meter depth during low tide. One of coral species i.e. Acropora  sp with 48 fragments was put on 4 transplantation tables. During the experiment, cleaning of fungi and biofouling at the transplant tables and the culture tables. Measurements of the absolute growth and survival rate were done at the 21st day using calliphers and numbers of dead and live fragments were counted directly. Coral transplantation workshop for ornamental coral culture was attended by 4 fisherman groups with total 23 participants. This event was understood by the training participants from the seed selection to the monitoring. Number of coral fragment cultured was 48 fragments obtained from one of stony corals (Scleractania), i.e. Acropora  sp. The range of survival rate that has been cultured for 21 days was adequately high i.e. 91.7 – 100 %. The highest survival rate was observed at the transplant table B, i.e. 100%, whereas, the table A, C, and D were 91.7 %. Average absolute growth of the coral Acropora  sp cultured during this study were ranged from 4.2 – 4.9 mm/month. Aaverage absolute growth was found at table transplant B and C, while the lowest value was observed at the transplant table D.Keywords: cultivation, ornamental coral, transplantation technique, Tonyaman

Abstract

Collecting the spectral library of different bottom types is an important step in mapping shallow water bottom types with of remote sensing. Five small islands in the Spermonde archipelago, South Sulawesi, Indonesia, were selected to measure the reflectance spectral of benthic communities. The objectives of this study are to determine optical properties of the live corals, dead corals covered with algae, coral rubble, broken shell, sand, seagrass and to collect a spectral library of bottom types present around small islands in the Spermonde archipelago. Several benthic communities appear to be highly correlated with one another when the entire spectrum considered, which may lead to classification errors. Porites meyeri,dead corals and coral rubble (>3 months ago) share a high degree of similarity in reflectance. The other coastal benthic communities are readily distinguishable.Keywords : Spectral, Coral Rubble, Living Corals, Dead Corals, Broken Shell ABSTRAKPengumpulan pustaka spektral pada berbagai jenis dasar perairan merupakan langkah yang penting dalam memetakan karakteristik dasar perairan dangkal dengan menggunakan teknologi penginderaan jauh. Pada penelitian ini, pengukuran reflektansi spektral pada komunitas bentik perairan dangkal dilakukan pada lima pulau-pulau kecil yang terdapat di Kepulauan Spermonde, Sulawesi Selatan, Indonesia. Tujuan dari penelitian ini adalah selain menentukan karakteristik optik pada karang hidup, karang mati yang ditumbuhi alga, pecahan karang, pecahan cangkang, pasir dan lamun juga untuk membangun pustaka spektral berbagai jenis obyek dasar perairan dangkal yang terdapat di sekitar pulau-pulau kecil Kepulauan Spermonde. Beberapa komunitas dengan jenis komunitas bentik lainnya menunjukkan korelasi yang kuat yang akan menghasilkan kesalahan klasifikasi jika menggunakan julat spektrum yang lebar seperti antara karang Porites meyeri, karang mati yang ditumbuhi alga dan pecahan karang yang telah berumur lebih dari 3 bulan menunjukkan tingkat kesamaaan reflektansi spektral yang tinggi. Sedangkan pada obyek dasar perairan dangkal lainnya, nilai pantulan spektralnya dapat dipisahkan.Kata kuci : Spektral, Pecahan Karang, Karang Hidup, Karang Mati, Pecahan Cangkang.

Abstract

This study was intended to design network of the conservation areas having high resilience to the environmental changes. Method applied in this study was field survey method, analysis of remote sensing images, and integration of geographical information system (decision support) Marxan Model. Results of this study showed that the western coast of South Sulawesi has biophysical relationships caused by oceanographic influence particularly seawater current and highly supporting the development the network of the conservation areas with regional principle. The optimum value for the establishment of the conservation areas was 66553,13 Ha with protection target of 20% from the available ecosystems.
