Abstract

Research on transplantation of Acropora microphthalma was conducted at Barrang Lompo Island reef edge of South Sulawesi from September to December 2002. The aim of this research was to know the successful rate of several coral transplantation methods for rehabilitation of coral reefs, covering the survival and growth rates. The methods used were framework earthenware (FE), iron stake (IS), dead coral tying (DCT), where the mother colony (MC) was used as control. These transplantation techniques were applied at five meter depth in two stations, north and south sites of the island. The survival rate for each method FE, IS, DCT and MC at the northern station was 85.71; 42.86; 85.71; 57.14%, while for southern station was 85.71; 85.71; 71.43 and 85.71%, respectively. The growth rates observed for each method at the first station were 2.18; 2.02; 1.40; 1.05 cm, and for the second station were 2.56; 2.21; 1.61; 1.04 cm, respectively.

Abstract

The efficacy of povidone iodine as a surface disinfectant was assessed in white shrimp (Litopenaeus vannamei) eggs and larvae. Eggs and nauplii were exposed to povidone iodine 20 ppm for 20 seconds. Culture-based method and Terminal Restriction Fragment Length Polymorphism (T-RFLP) were used to monitor the total number of bacteria and diversity of the bacterial community associated with shrimp eggs and larva at each developmental stage. Povidone iodine reduced the total culturable bacteria, especially Vibrio, on eggs and nauplii, as well as the total bacteria in the whole community as estimated by T-RFLP results. Povidone iodine also reduced the diversity of bacterial community and altered the evenness of phylotypes distribution suggesting that the use of povidone iodine as a surface disinfectant in shrimp aquaculture should be reconsidered.

Abstract

Indonesia is the largest archipelagic country in the world, composed of 18,110 islands with a coastline of 108,900 km long, extending some 5000 km long and 2000 km wide located between Asia and Australia. Coral reefs have important meaning and value for the coastal communities in term of economic, social, and cultural conditions. About 1.5 million people are traditional fishermen who live in subsistence level and depend on their lives fully on coral reefs' resources. The Indonesian coral reef contributed 14% of the world, distributed unevenly from Sabang to Merauke with the highest concentration around Sulawesi and Maluku. The species richness and the biodiversity of the Indonesian corals amounted to 590 species belonging to 82 genera or about 80% of the currently existing coral species in the world. Monitoring program has been done from 1993 to 2010 and it shows the trend of improvement in the term of live coral cover. The condition of coral reefs in Indonesia taken from 84 locations and 1048 sites were 50.54% in excellent condition, 26.72% in good condition, 37.21% in fair condition, and 30.82% in bad condition. Improving trends in live coral cover across all project sites shows that the live coral covers has increased in all monitored sites across all project districts with average yearly live coral coverage increase is about 2-5%. The National Policy, Strategy, and Action Plan was established, with its main objective of managing the coral reef ecosystems based on the balance between conservation and utilization, and it was reflected in the Law No. 27 of 2007 concerning coastal management and small islands. The most remarkable result of the program is community awareness, namely the decrease of fishing activities shows that the destructive fishing activities in all project district are now non-existent of at a minimal level. A special text books on marine lives for elementary, secondary, and high school is the most widely adopted by local education service as a book of local content. Whereas institutional strengthening program constitutes the most difficult, energy and time consuming activities. It is due to the rivaly between the local institution and the lac of officials' and the communities' knowledge on the conservation based management principle.

Abstract

In 2006, the amounts of seagrass products floating away and depositing were measured by in situ cage experiments in a monospecific seagrass meadow of Enhalus acoroides in Gilimanuk Bay, Bali Island. Results showed that the average rates of the floating and depositing leaves were 4.03 + 0.28 and 7.95 + 0.31 gram dry weight shoot-1 day-1 respectively. To express it in another way, about 66.4 % of seagrass production was deposited on the seagrass bed and 33.6 % floated away from the seagrass bed.

Abstract

Addressing to the environmental and energy crises in Indonesia, the new alternative of green-economic-energy sources is required. In this study marine microalgae were isolated from oil-polluted coastal zone in Batam Island for alternative energy sources. The research was carried out by collecting the sea water samples from several peninsulas of Batam Island. The abundance of microalgal diversity was observed. The isolation was done by capillary micropipette technique. The method of specific screening for hydrocarbon-producing microalgae was done using selected media, CO2 rate and light intensity period treatments. The results showed that the Cyanobacteria and diatom occupied the Batam's coastal waters. From the isolated samples, 11 strains positively deposit the hydrocarbon in their cells. Further study for determining the isolates and their properties is still in progress.

Abstract

The metabolites from microorganisms are a rapidly growing field, due to the suspicion that a number of metabolites obtained from reef's invertebrates are produced by associated microorganisms. Less than 2% of microbial flora has been successfully isolated from marine environment. Coral reefs are the most diverse marine ecosystems, however, little is known about the microbial diversity in these ecosystems. It is expected that still quite a few parts of unexplored culturable invertebrate-associated microorganisms exists in the reef environments. The present study aimed at estimating the biodiversity of secondary metabolite-producing microbes associated with reef's invertebrates such as coral, soft coral and sponge collected from geographically different areas.

Abstract

In order to understand biodiversity, distribution, and abundance among the tropical anguillid eels in the Indonesian waters, inshore migration mechanism of the juvenile anguillid eel (glass eel) to the estuaries of western, central, and eastern region of Indonesian waters were examined using both morphology and genetic analyses. A total of 9 species/sub species of anguillid eels (Anguilla bicolor bicolor, A. nebulosa nebulosa, A. bicolor pacifica, A. interioris, A. borneensis, A. celebesensis, A. marinorata, A. obscura and A. megastoma) were recognized to recruit at the mouth of 15 rivers through Indonesian archipelago. Species/subspecies diversity and distribution of recruiting juveniles differs in the estuaries of each region. In the western region that represented by estuary of Krueng Aceh, Batang Antokan, Air Kertaun, Cibaliung, Citanduy, Progo, and Pacitan Rivers, three species and sub species (A. bicolor bicolor, A. nebulosa nebulosa and A. bicolor pacifica) were found. In the central region that represented by estuary of Mahakam, Palu, Dumoga, Poigar, Bone, and Poso Rivers, five species and sub species (A. borneensis, A. celebesensis, A. marinorata, A. bicolor pacilica and A. interioris) were found. In the eastern region that represented by estuary of Akelamo and Pami Rivers, four species (A. marinorata, A. interioris, A. obscura and A. megastoma) were found. During the 6 months investigation from May to October 2005, abundance of the juveniles was higher in the central region compared with western and eastern regions. These results were suggested that inshore migration mechanism of tropical anguillid eels recruiting in tropical estuaries of Indonesian waters differs among regions.

Abstract

Several series of trawl surveys were carried out in the waters of Perhentian Islands using commercial trawlers. 16S mitochondrial rRNA gene sequences were used to infer the phylogenetic relationships among nine morphospecies of leiognathids. The results showed that the genus Leiognathus is paraphyletic, whereas Gazza secutor, Photoplagios, Photopectoralis and Nuchequula are monophyletic. The molecular phylogenetic posions of the leiognathids studied were identical with morphological delineation, except for Photoplagios stercorarius. Branch of P. stercorarius was placed between Photoplagios spp. clade and clade of Secutor and Gazza. P. stercorarius was more affiliated to genus Photoplagios morphologically however have slight different features of light organ system compared with others three Photoplagios sp. caught in this study. It is probable that two distinct subclades occur in genus Photoplagios. Leiognathus equulus formed the base of the other leiognathids. Leiognathus splendens and Leiognathus jonesi formed a sister taxa to Photopectoralis species. Gazza formed a sister taxa to Secutor and Nuchequula formed a sister taxa to the group of trifurcation but toth with low bootstrap support. This study has shown that 16S mitochondrial rDNA is a good marker for phylogenetic analysis of the Leiognathidae.

Abstract

Study on estuarine fishes in Mimika district, Papua was carried out at six estuaries from 2000 to 2006, as a part of monitoring program conducted by PT Freeport-Indonesia. This study mainly aimed to document the fish diversity, dominance, abundance and weight. Samples were collected from six estuaries, namely Ajkwa (tailing affected estuary), Tipoeka (disturbed estuary), Minajerwi, Kamora, Mawati and Otakwa (tailings unaffected estuaries). The total fish catches from the study sites during the study were 133 species belonging to 50 families, with the total abundance and wet weight were 85,523 individuals and 1,834 kg, respectively. The indices of diversity and evenness ranged 1.1-2.1 and 0.4-0.8, respectively. Based on the sample abundance, the dominant families consisted of pony fishes (Leiognathidae), drum fishes (Sciaenidae) and anchovies (Engraulidae), catfish (Ariidae) and glassfish (Ambassidae), whereas based on the samples weight, the dominant families comprised of Sciaenidae, Ariidae, Leiognathidae, Engraulidae and Clupeidae. The results show that there were no significantly differences in diver-sities and abundances among the six estuaries of Mimika district.

Abstract

Histological examination of gonad of female redbelly yellowtail fusilier Caesio cuning was carried out in order to describe the oocyte development and annual changes of ovarian composition. The oocyte development was devided into seven stages: peri-nucleolus (PN), oil-droplet (OD), primary yolk (PY), secondary yolk (SY), tertiary yolk (TY), migratory (M) and maturation (Mt) stages. The histological examination of ovarian composition showed that the fish had three peak spawning seasons: in June-July, October-November and February-March. Various kind of developing oocytes found in the same ovaries suggested multiple spawner and asynchronous type of ovarian dynamic.
