Coral Reefs in Indonesia: A Review on Anthropogenic and Natural Disturbances
Meinita, Maria Dyah Nur ;
Journal of Marine Bioscience and Biotechnology, volume 2, issue 1, 2007, Pages 1~10
Coral reefs are among the most dynamic and various ecosystems on tropical ecosystem. They provide a large number of important ecosystem services. Despite their importance, they appear to be one of the most susceptible marine ecosystems. Dramatic decreasing of coral reefs has been reported from every part of the world. Indonesia contains 18% of coral reefs of world's total. Unfortunately the status of coral reefs in Indonesia is already in critical and poor condition. Coral reefs communities in Indonesia are subjected to a variety of environmental disturbance. Threats to Indonesia's coral reefs resources can be divided into two main types: anthropogenic and natural disturbances. The major anthropogenic disturbances on coral reefs in Indonesia are destructive fishing, pollution, coastal development, mining and harvesting live fish and coral, tourism. The natural disturbances such as cyclones, volcanic eruptions, earthquakes, tsunami and predator also contribute to coral reefs destruction in Indonesia. In my paper I tried to compare between natural and anthropogenic disturbances on coral reefs in Indonesia and raised these questions: (i) how the natural disturbances differ from anthropogenic area (ii) which type of disturbances has caused the greatest impact on coral reef ecosystem. My finding is that both of anthropogenic and natural disturbances give major impact on coral reefs in Indonesia. The important issue here is coral reef resilience could be disturbed by synergistic effects between various anthropogenic and natural disturbances. This phenomenon has significant conservation and management implication. The appropriate management should be conducted to protect coral reefs ecosystem in Indonesia. Mangrove management will succeed only when local people are involved and get sustainable benefits from mangrove ecosystem. Community based management and Integrated Coastal Zone Management (ICZM) are type of management that can be applied on coral reef ecosystems in Indonesia.

This aims to review natural products transformed by mimic intestinal metabolisms with microorganisms and hydrolytic enzymes, which exhibit enforced biological activity, higher extraction yield and identification of active components. In the process, transformation to the smaller active compounds with enzymes and microbes mimics the pharmacological action of natural products by intestinal bacteria. In order to establish conditions for the fermentation and enzyme reaction, it is required to choose several natural products for biotransformation and investigate the optimal conditions for the fermentation or the enzyme reaction such as composition, temperature, pH, inoculum, and cultivation time. It is expected an increase of the internal absorption of the active materials without regard to the intestinal microbes or its ability through biosynthesis of the active materials by the microbes and enzymes. And this techniques can be applied to biotransformation of natural products such as sesaminol, resveratrol, 1-deoxy nojirimycin, naringenin, quercetin, and baicalin and to the metabolism study using the animal model.

Journal of Marine Bioscience and Biotechnology, volume 2, issue 1, 2007, Pages 23~33
The constraints of traditional fish drying in Bangladesh have been reviewed and an effective solar fish dryer was developed with the small-scale processors and fishermen using locally available cheaper materials in order to dry fish in coastal region. After successful field testing, new solar dryer was demonstrated within the community in 3 different locations of Cox's Bazar for several batches of operations in each location from late September to March and found very effective in terms of architectural suitability, operational feasibility, technical efficiency, out-put quality (good texture, colour, flavour and long storage time), user's acceptability, commercial viability and environmental adequacy. A simple cost-profit analysis was done with the community operated products, which indicates that the new solar fish dryers could be operated profitably in coastal regions where sun-light and air flows are abundant.

Penaeidins are members of a special family of antimicrobial peptides existing in several species of shrimp and play a crucial role in the immunological defense of shrimp. In this study, we isolated and characterized one EST clone (penaeidin) from cDNA library of fleshy prawn Fenneropenaeus chinensis hemocytes. Amino acids sequence comparison and phylogenetic analysis with other known penaeidins revealed that our clone was completely identical to F. chinensis Penaeidin 3-2 (Accession no. ABC33920), which composed of 71 amino acids with a putative signal peptide (1-19) and a cysteine-rich domain (C-terminal part). The expression and distribution of Penaeidin 3-2 transcripts in shrimp were detected in hemocytes, hepatopancreas, and muscles, and that Penaeidin 3-2 was constitutively expressed mainly in hemocytes. The artificial infection of white spot syndrome virus to F. chinensis resulted in Penaeidin 3-2 mRNA up-regulation in hemocytes, suggesting that the possible role of Penaeidin 3-2 in host defense system of F. chinensis.

Golda farms and depots of selected areas of the different districts of Bangladesh viz. Khulna, Bagerhat, Jessore and Norial area were sampled for the detection of Salmonella sp. and Escherichia coli. Incidence of Salmonella positive samples was 39%, 25%, 50% and 42% in the farms and 30%, 20%, 20% and 30% in the depots of Dumuria under Khulna, Bagerhat Sadar under Bagerhat, Avoynagar under Jessore and Kalia under Norail district respectively. On the other hand, E. coli positive samples was 23%, 42%, 25% and 17% in the farms and 70%, 30%, 50% and 30% in the depots of Dumuria (Khulna), Bagerhat Sadar (Bagerhat), Avoynagar (Jessore) and Kalia (Norail) region respectively. The overall results indicate that the trend of Samonella and E. coli contamination in farms and depots of all the regions is more or less similar although some variations were observed among the farms and depots of different location and region.

Bacillus polyfermenticus SCD (B. polyfermenticus SCD) has been appropriately used for the therapy of long-term intestinal disorders, because live strains in the form of active endospores can successfully reach the target intestine in humans. B. polyfermenticus SCD produces the most antibiotic-related materials. In the present study, B. polyfermenticus SCD was fermented with soybeans (BPFS) and its probiotic properties were investigated. B. polyfermenticus SCD and BPFS showed a broad spectrum of antimicrobial activity against pathogenic Gram-positive (Streptococcus parauberis, Streptococcus iniae, Lactococcus garviae) and Gram-negative (Flexibacter tractuosus, Vibrio harveyi, Vibrio vulnificus, Vibrio ordalii) bacteria and moulds (Aspergillus niger, Aspergillus oryzae). Sebastes schlegeli were used to examine survival rate and cleanup action by BPFS. Bacterial infection resulted in a mortality of up to 99% in the commercial fodder fed groups. BPFS both enhanced the growth rate of fry by improving their appetite and had cleaned by decreased eutrophication. Therefore, it seems appropriate that BPFS should be developed as an antibiotic replacement, favorable fodder additive, and antifungal material in fish farming systems.

The oil and concentrated protein powder from squid viscera was extracted and recovered by a semi-batch supercritical carbon dioxide (
) extraction system and the degree of oxidation in the extracted oil was measured in order to compare with extracted oils using organic solvents. The degree of storage in treated squid viscera by
extraction was measured in order to compare with untreated squid viscera. As results obtained, it was found that the auto-oxidation of the oils using
extraction occurred very slowly compared to the oils by organic solvent extraction. And the treated squid viscera by
extraction was reached the point of initial rottenness slowly than untreated squid viscera.

For the first time in Vietnam, morphological and molecular studies of a species belonging to Bacillariophyceae collected in Northern coast of Vietnam are presented. Observations with microscope showed that this species belong to genus: Pseudo-nitzschia and seem like P. pungens. Sequence data from the partial 18S small subunit ribosomal RNA gene (18S rDNA) and the internal transcribed spacer 1 - 5.8S - internal transcribed 2 have been used to determine clearly and generate a phylogenetic framework of the obtained sequences to previously reported sequences in GenBank. These results allowed us to highlight described species of Bacillariophyceae in Northern coast of Vietnam. Furthermore, accumulation of molecular study would be helpful for the identification of scientific name of harmful algal species and further taxonomic studies in Vietnam.

Flounder is one of the major aquacultured fish and of an economically important item in Korean fisheries. Recently, there are trends of research worldwide that aim to analyze and characterize a whole genome or a whole proteome of interesting species. The data are utilized for the understanding and development of preventive and curative technologies for the serious diseases. However, there are very limited information of proteome for marine organisms, we optimized first the conditions for two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) with serum form a marine fish, flounder (Paralichthys olivaceus). A pre-treatment of serum and an optimization of protein concentration analyzed were surveyed for enhancing the separation for proteins. A statistical analysis was performed on the overall 1,820 protein spots to overcome the variability among individual fishes.
