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 Batams 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

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.

Abstract

The study was conducted between September and October 2006 in various sites both inside and outside the Taklong Island National Marine Reserve (TINMAR), southern Guimaras, Philippines, to immediately conduct a rapid 3-month assessment of the impact of the Solar I oil spill incident which occurred in August 11, 2006 in southern Guimaras. The assessment was made possible by the availability of baseline (pre-spill) data which were compared with the present data (post-spill). Results showed the drastic decrease in overall mean densities (no. m-2) and species richness in the infaunal assemblages within TINMAR in September 2006, or 1 month after the oil spill. In October 2006 however, a slight increase in both of these parameters was observed, albeit not significant. The decrease is taken as a disturbance, directly resulting from the oil spill. On the other hand, it is not clear at this time if the increase is the start of recovery in the infauna. Our results indicate the need for a continuous monitoring, to allow more definitive conclusions on a) whether the assemblages are recovering, and if indeed they are, b) how long this recovery will take place.

Abstract

The metabolites from microorganisms are a rapidly growing field, due to the suspicion that a number of metabolites obtained from reefs 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 reefs invertebrates such as coral, soft coral and sponge collected from geographically different areas.

Abstract

Studies on artisanal fisheries of sharks and rays in Indonesia were carried out during 2001-2004. A market sampling method was employed to collect fisheries data from a number of major landings sites, namely: Pelabuhanratu and Cilacap in south coast of Java, Kedonganan in south coast of Bali and Tanjung Luar on the island of Lombok. Large proportions of the shark and ray landings were by-catch of tuna longlines and gillnets, and shark surface and bottom longlines from Tanjung Luar - east of Lombok. The shark landings were dominated by the families Carcharhinidae, Squalidae, Allopidae and Sphyrnidae, while rays were dominated by the Dasyatidae, Rhynchobatidae and Mobulidae. Most of the landings were processed to be dried and salted products for local consumptions. Some of them are exported to Asian countries. The most valuable part of sharks are their fins, which are a delicacy in Chinese cuisine. The major importers of Indonesian shark fins are Hongkong that contributed 46.3% of the total reported exports of shark fins from Indonesia.

Abstract

Nitzschia navis-varingica is recognized as the major ASP toxin producer other than Pseudo-nitzschia species. Surveys on the distribution and the toxin production of this diatom has been conducted in a few countries in eastern Asia and expanded to Thailand. Eighteen isolates from Thailand showed the positive result for the ASP toxin production is DA and IB, although the ratio of IB was much lower than those of the isolates from southern countries including Okinawa, Japan, the Philippines and Vietnam.

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

An investigation to find new anticancer substances from marine microorganisms was conducted at the Marine Biotechnology Institute, Kamaishi Campus, Iwate, Japan. The samples were from MBI microorganism collection. They were bacteria, actinomycetes and fungus. Mammalian cancer cells, A549, were used as screening medium. The method for screening of the targeted microorganism was micro plate method. HK294 was found as microorganism which has the most interesting phenomenon in inhibiting A549 cancer cells. HK294 was identified to be Streptomyces viridocyaneus (homology 99%) by its 16S rDNA sequence. The HK294 was cultured in Marine Broth medium and incubated at 30°C for seven days in 100 rpm orbital shaker incubator, to produce active substance. Silica Gel Column Chromatography and High Pressure Liquid Chromatography were used for separation of the active substances. NMR and Mass Spectrum were used for determination of the active substances. Butenolide, Teleocidin A1 and New Butenolide were isolated from this experiment. The New Butenolide is promising to be used for anticancer drug but it need further research.

Abstract

Recruitment pattern of juvenile fishes into Pami River estuary, West Papua, Indonesia (S 00.80970, E.134.06050), was studied from July to October 2005. The study purposes were 1) to observe fish diversity in family level, 2) to observe fish abundance of each family, 3) to observe recruitment pattern related to abundance and tidal rhythm. Samples were collected using line transect method and identification procedure were done based on morphological characteristics. A total of 19 Families were identified, namely Acanthuridae, Ambassidae, Anguillidae, Apogonidae, Carangidae, Chlopsidae, Clupeidae, Congeridae, Elopidae, Engraulidae, Gerreidae, Gobiidae, Mugillidae, Platycephalidae, Callyonimidae, Siganidae, Syngnathidae, Terapontidae, Tetraodontidae. Fishes composition varied each month.  Family of Gobiidae was the most dominant juvenile fishes recruiting during this study with 32%, 69.5%, 84.3%, 71.3%, respectively. Other 8 families (Ambassidae, Engraulidae, Elopidae, Chlopsidae , Siganidae, Syngnathidae,  Congeridae , and Callyonimidae) had the lowest composition varied from 0.4% to 3.2%. Three different patterns in abundance during the recruitment time of juvenile fishes, 1) early night (18.00-21.00) was represented by Ambassidae, Chlopsidae, Clupeidae, Gerreidae, Terapontidae, 2) mid-night (22.00-01.00) was represented by Callyonimidae, Congeridae, Engraulidae, Mugilidae, Platycephalidae, Tetraodontidae, and 3) late night (02.00-05.00) represented by Acanthuridae, Apogonidae, Carangidae, Elopidae, Gobiidae, Siganidae, Syngnathidae. However, the peak of abundance occurred at late night (>50 specimens caught), and recruitment pattern of all juvenile fishes has been associated with tidal rhythm.

Abstract

A research on zoobenthos biodiversity was carried out from September 2004 to September 2006 at the Ca river (the length of Nghe An and Ha Tinh provinces) showed a species composition consisted of 154 species, 115 genera, 72 families, 32 orders and 5 phyla, including Mollusca, Annelida, Arthropoda, Echinodermata and Sipuncula. The results showed that a decreasing trend in the number of zoobenthos species from the fresh water area to the estuary of the Ca River. The largest number of species was shown in route 1 (Cua Hoi) with 89 species (nearly 44.7%). The lowest value of species number was seen at route 5 with 31 species (15.5%). The Crustacea group was the most predominant group, including 47 species. The H and d indexes indicated a decreasing biodiversity level from route 5 (Hung Lam, H = 0.9 and d = 0.75) to route 1 (Cua Hoi, H = 2.32 and d = 1.96). The average number of zoobenthos density was 149 individuals per m2. The average value in dry season was higher than that in rainy season (151 individuals per m2 compared to 146 individuals per m2, respectively). In the dry season, the biological indexes changed mainly according to salinity and turbidity factors. Meanwhile, in rainy season, the variation of zoobenthos species related essentially to other factors, DO and salinity.
