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

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

This article provides a comprehensive review of the contamination by Butyltin compounds (BTs) and its possible implications on the marine and coastal environments of the Philippines. Butyltin compounds were detected in mussels from all the sampling locations investigated as part of the monitoring surveys under the Asia-Pacific Mussel Watch (APMW) Program conducted in the late 1990s. BTs were detected in green mussels collected from all the aquaculture sites in the country, suggestive of considerable widespread pollution by BTs in the coastal waters. Among BTs, TBT was detected at all locations at relatively higher concentrations, whereas the concentrations of DBT and MBT were lower. This could be indicative that green mussels have limited ability of metabolize TBT to DBT and MBT. In addition, this result may be suggestive of fresh TBT inputs into the aquatic environments and the presence of recent sources along the coastal waters. Concentrations of 0 BT in green mussels were reported up to 790 ng/g wet weight in a site where intensive maritime activities are occurring. Mussels from rural areas contained TBT at lower proportions indicating that TBT usage as antifouling agents is minimal. Tolerable average residue level (TARL) for seafood in the Philippines was estimated at 173 ng/g wet weight for an average person weighing 60kg. Concentrations of TBT or the sum of TBT and DBT in some green mussels analysed revealed that some values exceeded TARL level, which could suggest that humans consuming this seafood from areas with high BTs contamination could be at risk from elevated exposure to BTs. Similarly, BTs were detected in all the skipjack tuna collected, suggestive of the widespread contamination even in offshore waters and open seas on a global scale. Skipjack tuna collected from the offshore waters of the Philippines revealed considerable levels (up to 220 ng/g wet weight), with high percentages of BTs in total tin (0Sn: inorganic tin + organic tin) in the liver tissues. This finding seems to suggest that the anthropogenic BTs represent the major source of Sn accumulation in skipjack tuna. On the other hand, relatively low concentrations of BTs were found in the liver of cetaceans from the coastal waters of the Philippines, which ranged 42-98 ng/g wet weight. Significantly lower hepatic BT concentrations in cetaceans in tropical waters were noted compared with those inhabiting temperate waters proximal to developed nations. This result could imply smaller usage of BTs in the Philippines at least at the present.

Abstract

Sediment of 16 sites in the Kelabat Bay were monitored for metal contamination and toxicity in 2006. Two patterns of metal contaminants distribution in the sediment were observed. Higher concentrations of lead and copper were found in March than those in July, and so was in the inner bay than those observed in the outer bay, while different pattern was observed for cadmium concentration. The highest lead concentrations were observed at site 7 (inner bay) both in March and July. Although elevated levels of cadmium, lead and copper were observed in sediments, they were still in the tolerable level for marine life. Sediment of the bay was also evaluated for its toxicity using marine phytoplankton, Chaetoceros gracilis and sea urchin, Tripneustes gratila. Results of the tests reveal that no toxic effects of sediment to the growth of phytoplankton were observed, but to sea urchin fertilization of the sediment may have toxic effect.

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

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

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.

Abstract

A small-culture system for growing of Halophila ovalis was developed. Plugs of explants were successfuly grown in the native substrate and under the light regime of ~200 imol m-2 s-1. The culturing of H. ovalis in the laboratory permitted observations on (i) the sustain growth and the development of the population, (ii) the reproductive biology (flowering and fruiting) and (iii) the pattern of seedling development from seeds to mature plants. Plants increased in density via vegetative propagation and sexual reproduction. Plants produced male, female flowers and fruits. The presence of viable seeds and seedlings demonstrated the successful pollination and sexual reproduction of H. ovalis in culture. The morphology of progressive development of H. ovalis seedlings to juvenile or young plants for H. ovalis in culture is described.

Abstract

The community structure of seagrass in Enggano Islands has been studied in August 2004. The aim of the study was to assess the seagrass community including species composition, density, and distribution pattern. The study was executed using transect quadrat methods, where seagrasses were counted in quadrats of 50 cm2. The result showed that the Enggano Islands seagrasses consist of seven species Enhalus acoroides, Halophila ovalis, Thallasia hemprichii, Cymodocea rotundata, Cymodocea serrulata, Halodule uninervis, and Syringodium isoetifolium. The highest density occurred in Dua Island dominated by Thallasia hemprichii (363.3 shoots m-2), while the lowest density occurred in Merbau Island dominated by Enhalus acoroides (0.4 shoot m-2). The highest diversity index (HB) occurred in Kiape Bay (1.446) and the lowest in Merbau Island (0.634). In general, seagrass community in Enggano Islands was dominated by Thallasia hemprichii. All species has clumped distribution pattern (Id > 1).

Abstract

Meiobenthos inhabiting the seagrass bed of Sungai Pulai estuary, Johor, was studied for the differences in community structure. Sampling was carried out using a hand corer during the lowest tide in December 2006. Three stations were chosen that were located at the upper estuary, lower estuary and at the sea area. Cluster analysis dendrogram of Bray-Curtis similarity showed the similarity level at about 70-75% and from the MDS plot, it is found that communities at upper estuary were separated from those at lower estuary and at sea. The differences in environmental setting were thought as the significant contributor to the distribution of meiobenthos among the stations.
