Abstract

A total of 13 bacterial isolates associated with sponges collected from Bandengan water, Jepara, North Java Sea, Indonesia, was successfully screened for antibacterial activity against pathogenic bacteria Vibrio parahaemolyticus, Aeromonas hydrophila  and Staphylococcus aureus. Active bacterial isolates were rapidly grouped by using rep-PCR and a dendrogram was constructed. Six isolates were further selected based on the constructed dendrogram for subsequent DNA sequencings, resulted in the richness of secondary metabolite-producing bacteria associated with sponges from Bandengan having closest similarity to Pseudoalteromonas, Brachybacterium, Vibrio, alpha proteobacterium and uncultured bacterium clones.

Abstract

Marine sponges (phylum Porifera) are among the oldest multicellular animals (metazoans), the sea’smost prolific producers of bioactive metabolites, and of considerable ecological importance due to theirabundance and ability to filter enormous volumes of seawater. In addition to these important attributes,sponge microbiology is now a rapidly expanding field. Marine sponges produce numerous bioactivecompounds with promising pharmaceutical properties. Sponges are well known to harbor diversemicrobes and represent a significant source of bioactive natural compounds derived from the marineenvironment. Recent studies of the microbial communities of marine sponges have uncovered previouslyundescribed species and an array of new chemical compounds. Microbial symbionts in marine spongesoffer potential sources of marine natural products and serve as marine natural product factory thatsupplies bioactive compounds in a sustainable way.

Abstract

The white spot syndrome virus (WSSV), the causative agent of White Spot Syndrome Disease (WSSD), is a major shrimp pathogen in Indonesia. Dendronereis spp. is a ubiquitous Polychaetes and natural food of shrimp raised in brackishwater pond in Indonesia. The objective of this research is to determine the occurrence of WSSV and the viral load in Dendronereis spp. obtained from the shrimp pond. Dendronereis spp. was obtained with PVC (10 cm in diameter) from a traditional shrimp pond in Semarang vicinity. As a comparison, healthy looking Penaeus monodon was also obtained from the same pond. The occurrence of WSSV in Dendronereis spp. was determined with 1-step and nested PCR using primer for WSSV major envelope protein, VP 28. The viral load was counted with 1-step Real Time PCR. The WSSV was detected in Dendronereis spp. with 1-step and nested PCR. The point prevalence of WSSV infection in Dendronereis spp. is 90 %. The viral load ranged from 0 to 1.9 x 104 copy of DNA/µg total DNA. The viral load in Dendronereis is comparable with that of naturally infected and at carrier state P.monodon from the same pond. This is the first report of WSSV load in naturally infected Dendronereis spp.

Abstract

The research of stock analysis of Metapenaeus elegans was held in Segara Anakan Lagoon, Cilacap CentralJava. This research were aimed to study the carapace length of optimal capture, exploitation rate optimumand maximum sustainable yield relative. The research were carried out by using survey method and thesample were collected by systematic random sampling method. Sampling conducted over 11 months, fromFebruary until December 2004. Data was analyzed using ELEFAN in FiSAT II software. The result showthat rate of exploitation of M. elegans was 0.83 / year, and the length of first capture of the M. elegans was14.5 mm. At 14.5 mm carapace length, the rate of exploitation (E) should be 0.51 / year, and E0.1 was 0.47 /year. The average biomass of exploited for 24% of the initial biomass, which has exceeded the ideal limit of10% (E0.1 concept). According to the above three indicators (the carapace length of shrimp, exploitation rateand biomass used), then the exploitation of M. elegans in Segara Anakan Lagoon has been consideredseriously over-exploited. The rate of exploitation has reached 154% of Emsy and 177% of E0.1. Based onsimulation results, the size of carapace length of first capture that produces the MSY is a minimum carapacelength of 21.3 mm, and the rate of exploitation (E) can reach 0.7 / year.

Abstract

Human impacts, coupled with global climate change are placing increased pressures on coastal environments. During the last three decades, in response to the growing problems of coastal zones, many countries have introduced Integrated Coastal Zone Management (ICZM) as a mechanism to effectively manage the coastal zone and the conflicts of interest arise from competition for coastal space and resources. However many ICZM schemes in the developing countries have failed at the implementation stage as a result of inadequate institutional and management capacity, as well as a lack of decentralization for the community in implementing local integrated coastal management. Hence, decentralization of ICZM is necessary to deal with the extensive geographical problems and the tremendous social and cultural diversity of communities. Egypt provides an excellent case study of this experience. Since the mid-1990s several attempts have been made towards decentralization in Egypt, the process is still in its initial stages and needs support to enhance ICZM implementation. This paper reviews ICZM process in Egypt focussing on discussing decentralization in planning and implementation of ICZM based on interviews with key ICZM actors as well as documentary analysis. It seeks through a critical evaluation to provide some practical recommendations that could help to enhance the implementation of ICZM in Egypt.

Abstract

This study was aimed to assess the level of fishers’ participation alleviation programme in two less-development villages at the coastal area in Pemalang District, Central Java. The study found that to a certain extent, the poor fishers have participated in the four phases of the programme accomplishment: in decision-making, implementation, sharing benefits, and evaluation. However, the intensity of participation in each phase was low. Several effort to improve fishers’ participation in the programme such as providing appropriate technical and management advisory support and sufficient information to the target members were recommended.

Abstract

Since there were many evidences on trawling impact to the environment and society, government has banned trawl operations in Indonesian waters except for those in the Arafura Sea. It is not solely acquitted trawl operation in the area without restrain, but it has been put together with the measures taken to exploit the shrimp resources in optimal manner. Those are input controls, output controls and technical measures. This paper examines two major challenges in applying these management measures: declining of shrimp stock and lack of legal enforcement. Come what may the fishing regulations impose in the shrimp trawling, without effective enforcement, the purpose of fisheries management unlikely will be achieved.

Abstract

Freshness quality is considered as an important factor in determining overall quality of particular fish product items. The degree to which the freshness quality of the items meets the consumer’s expectation concerning freshness quality will greatly affect whether the fisheries product item will be purchased again or not. Considering the importance of fish freshness quality, many methods have been proposed to evaluate fish freshness including physical, chemical and sensory methods. The K value is one of  the chemical methods widely used , especially in Japan, as a fish freshness index to evaluate the quality change of raw fish. Tuna has been regarded as a palatable and valuable fish species and its freshness is  the  concern of many  researchers. This study is aimed at investigating the freshness change of yellowfin tuna (Thunnus albacares) during storage at low temperatures (10oC, 5oC and 0oC) by measuring the K value of the fish. Observation on the changes of ATP and its related compounds during storage was also carried out. The result of the study shows that the freshness of yellowfin tuna as measured by K value, changed in different patterns depending on the storage temperatures. The higher the temperature of storage the faster was the decrease in freshness of yellowfin tuna. It was also observed that yellowfin tuna could be eaten raw up to 1 day, 2 days and 4 days storage at temperature of 10º C, 5º C and 0º C, respectively. Storage temperature of 0º C is recommended for its preservation in chilled state. The use of HPLC allows for each of ATP-related compounds to be determined quantitatively.The Ki value is more appropriate for measuring fish freshness obtained more than 24 hours after death

Abstract

Our previous study found that KLU 11.16, isolated from shrimp waste secreted chitinolytic enzymes. The crude enzyme was interesting since their chitooligosccharide was able to inhibit some pathogenic bacteria. In this study we report a purification and characterization of the chitosanase enzyme produced and the identification of the KLU 11.16. Purification of the enzyme was done two steps by ion exchange chromatography followed by gel filtration. Two out of 4 peaks from Gel Filtration step, i.e. fraction 16 and 33 were capable of hydrolyzing 100% deacetylated chitosan, indicating that both fractions contained chitosanase enzyme. The enzyme from fraction 16 had approximate molecular weight of 98.3 kDa. The enzyme worked optimally at temperature of 300C, and pH 6. Addition of Ca2+, Fe2+, K+, Na+ ions in the form of Cl2 salt and detergent Triton X-100 increased the enzyme activity, while Co2+, Mn2+ and Zn2+ ions in the same concentration decreased the enzyme acitivity. Addition of EDTA and SDS significantly decreased the enzyme activity. Molecular based identification revealed that KLU 11.16 was 99% similar to Aeromonas media.
