ANALISIS KERAGAMAN GENETIK PADA IKAN KERAPU MACAN (Epinephelus fuscoguttatus) YANG TAHAN TERHADAP PENYAKIT YANG DISEBABKAN BAKTERI Vibrio alginolyticus Triana, St. Hidayah; Gani, Mahir S.; Malina, Asmi Citra

The research was purposed to analyse genetic similarity of tiger grouper (Epinephelus fuscoguttatus) inorder to select grouper that was resistant to Vibrio alginolyticus. In this study, fish were challenged with Vibrioalginolyticus and genetic similarity was examined by a PCR-RAPD method. Eight RAPD primers were used forPCR-RAPD analysis. The results showed that only three primers of RAPD primer (YNZ-22, UBC-456, danUBC-457) generated high number of RAPD fragments. The resistant group of tiger groupers generated higherpolymorph RAPD fragments than the susceptible groups. RAPD primer YNZ-22 and UBC-457 generated 82 %and 71 % of RAPD polymorph fragments from resistant group of fish and 71% and 60 % from susceptiblegroups, respectively. Primer YNZ-22 is a best genetic marker to analyse genetic similarity of tiger groupersproduced specific marker ranging from 1,2-2,0 kb. Genetic distances between the population of resistant fishand population of susceptible fish was 0.5091 and between individual of the resistant fish and susceptible fishwas 0.7032. Keywords: Genetik diversity, Epinephelus fuscoguttatus, V. alginolyticus, PCR, RAPD.

The objective of this study is to characterize benthic substrate of Bonetambung reef area using worldview 2 highresolution satellite imagery. About 14.273 depth spot were deploy to build bathimetric model of the study area. The correlation of pixel radiance value from satellite imagery and depth value from field measurement werebecame the basis to classify geomorphologic zone of shallow water area up to 7 meter depth. Between threeinterpolator tested, the natural neighbor interpolator has produced the best bathymetric model with root meansquare error 0.3 meter and benthic substrate coverage model with thematic accuracy 62%. These approach beable to recognize four substrate type in general, such as sand, seagrass, rubble and coral. Geomorphicsegmentation based on bathymetric profile and radiance value of worldview 2 imagery may also maps the reefflat, reef slope and lagoon area hence may support the benthic substrate modeling. This study showed us apotential technic to develop a modelling for juvenile fish transport at Bonetambung coral waters.Key words: benthic substrate bathymetry, worldview imagery, thematic accuracy

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

Areolate grouper is kinds of fish that exploited by fisherman in Galesong Kota Village. This is causedthe decreased of it population and concerned to be extinct, therefore conservation is in efforts. This researchaims to find out some biological aspect of areolate grouper such as, sex ratio, gonad maturity level(GML),gonad maturity index(GMI), and first time size of mature gonad. This research held on March-May 2013 inGalesong Kota Village, Takalar Regency. Applied method in this reseach is Descriptive Method. Gonadobservation conducted morphologically. The results of the showed that morphological ratio between female,transition and male 8 : 1 : 9. GML I, III, IV, and IX dominant in March, GML II, VI, VII, VIII, X, and GML Vdominant in May. Highest GMI rate of female phase is on May, with GMI average 0,6600%, highest GMI phasetransition on April with GMI average 1,3619%, and highest GMI of male phase is on April with GMI average0,7709%. Areolate grouper size of female phase for the first time of mature gonad at length of 230 mm andweight of 223 gr and male phase at body length of 290 mm and weught of 284 gr. Keywords : areolate grouper, biological aspect, Galesong Kota

Information about potency and utilization of Skipjack Tuna in Bone Bay region will support regionalmanagement of fisheries resources in Indonesiabased on characteristic and carrying capacity of marine waters,espcially in Bay region. The aims of this study were to estimate potency of Skipjack Tuna and the level of theirutilization in Bone Bay region and to estimate the primary productivity produced by euphotic zone (Pp).Analysis methods used in this study were catch per unit effort(CPUE) and maximum sustainable yield (MSY),vertically generalized production model (VGPM) which required data of photosynthetically active radiationanddepth of euphotic zone, fish production model by considering energy transfer efficiency among trophic level.This study was conducted for eight months in Luwu Regency.The result of the study showed that the utilization ofthe Skipjack Tunawas bigger than the MSY,.The Ppeu was in the range of 483.3143to 1306.027 mgC m. The Skipjack Tuna biomass estimation was in the range of 97.87 to264.47tonnes Keywords : Skipjack Tuna, utilization, potency, fisheries management, Bone Bay

Mangrove ecosystem in Muna Regency,includingKembarMaminasa village, has been started to be exploited bythe local community. Unfortunately information about mangrove status and their condition are still negligible.The result of this study is useful to provide basic information for sustainable management of mangroveecosystems. A study of mangrove community structure was conducted at the Tembe River inKembar Maminasavillage, from September to November 2013. Mangrove community structure was analyzed using non-metricmultidimensional scaling technique and Bray-Curtis cluster analysis, while the most contributed species todifference of fish community structure was analyzed using SIMPER (similarity of percentages) procedure. Thedifference between the community structure in three different substrates(muddy, mud-sandy, sand-muddy) wasanalyzed using ANOSIM. All the statistics analysis were carried out using PRIMER v6 software.The results ofthe study showed that there were seven species found in the Desa Kembar Maminasa and they tended todistribute differently among three different substrate, creating three slightly different zones of mangrove fromseaward to landward. The community structure of the mangrove trees were different among the three differentsubstrates. Similar results were found in community structure of mangrove saplings and mangrove seedlings. Key words: District Muna, community structure of mangrove, mangrove tree, mangrove saplings, mangroveseedlings.
