Abstract

Penelitian ini bertujuan untuk mengetahui distribusi telur menurut tingkat perkembangannya, rataan jumlah telur per polip dan proporsi polip yang reproduktif pada berbagai bagian cabang karang A. nobilis. Sebanyak 10 koloni A. nobilis yang berdiameter > 15 cm diambil contohnya secara acak di bagian barat laut perairan terumbu karang Pulau Barrang Lompo, Kepulauan Spermonde, Makassar pada tanggal 27 Januari 2002 (satu hari sebelum bulan purnama). Polip dari tiga bagian cabang (apikal, tengah dan basal) diperiksa jumlah telur yang dikandungnya secara histologis. Terdapat interaksi antara pertumbuhan dan reproduksi terhadap alokasi sumber daya pada berbagai bagian koloni karang. Alokasi sumber daya terhadap fungsi biologi tertentu akan mengorbankan fungsi biologi lainnya. Pertumbuhan karang yang terlokalisasi pada bagian tertentu suatu koloni karang berhubungan dengan rendahnya aktivitas reproduksi. Hasil penelitian menunjukkan adanya perbedaan yang nyata (p < 0.001) distribusi telur menurut tingkat perkembangannya pada berbagai bagian cabang karang. Bagian tengah cabang memiliki proporsi polip karang yang berkaitan dengan lokasi energi untuk pertumbuhan yang lebih reproduktif (100%) dengan kandungan rataan jumlah telur yang lebih tinggi (5.22 butir/potongan polip) dibanding bagian apikal dan basal cabang.Kata kunci: Distribusi, telur, cabang karang, Acropora nobilis

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

Terumbu karang telah mengalami degradasi yang serius oleh berbagai aktivitasmanusia. Di sisi lain, nelayan pesisir sangat bergantung pada perikanan terumbukarang. Terumbu karang memberikan beberapa fungsi ekologi terhadap biotalaut (ikan dan invertebrata), yaitu sebagai daerah pemijahan, daerahpembesaran, dan daerah mencari makan. Terumbu karang yang sehat denganstruktur bio-fisik yang kompleks akan menyediakan makanan yang maksimalterhadap pelbagai organisme, menyediakan mikrohabitat yang baik untukberlangsungnya proses-proses reproduksi dan perlekatan larva, dan memberiperlindungan fisik dari predator (khususnya untuk larva). Kerusakan terumbukarang akan memberikan pengaruh tidak hanya berupa penurunan keragamanhayati tetapi juga berdampak sosial-ekonomi bagi masyarakat pesisir (nelayan).Oleh karena itu, diperlukan kegiatan-kegiatan yang terkait dengan usaha-usahaagar dapat membatasi kerusakan tersebut (regulasi), dan melindungi ataumelakukan restorasi terhadap terumbu karang yang rusak.
