Abstract

This study was designed to evaluate fish silage made from various marine feedstuffs (shrimp head, blue crab waste, mud crab waste, squid and tigawaja trash fish) as potential sources of n-3 fatty acids for aquaculture feeds. The marine feedstuffs and the fish silage were analysed for fatty acids contents. Results of fatty acid analysis showed that all the fish silage had higher levels of PUFA (polyunsaturated fatty acid) of linolenic acid (LNA; 18:3n-3) and HUFA (highly unsaturated fatty acid) of eicosapentaenoic acid (EPA; 20:5n-3) and docosahexaenoic acid (DHA; 22:6n-3) than the feedstuffs. This study indicates that the bioactive substances contents of n-3 fatty acids (LNA, EPA, DHA) in squid can be significantly improved by manufacturing the fish silage. Fish silage from squid was found to be the most potential source for PUFA (LNA; 5.08 vs 10.72) and HUFA (EPA; 8.07 vs 17.50 and DHA; 7.18 vs 18.08 g/100 g lipid) among the others and suitable for aquaculture feeds.

Abstract

The paper review nutritional value and production of lupin meal and its uses in aquaculture feeds. Feed is the major cost variable in a aquaculture system representing up to 60% of total operating costs. The utilization of cost effective feeds would improve profitability of a aquaculture business. Commercial aquaculture feeds have been traditionally based on fish meal as the main dietary animal protein source and soybean meal as the dietary plant protein source. Lupin meal as an alternative dietary protein source has a favorable amino acids profile as compared to soybean meal. Lupin meal is consistently available, cost effective, palatable and highly digestible to most species of fish. It has been demonstrated that lupin meal will replace a considerable amount of soybean meal with no loss in production and fish performance. Manganese and methionine levels must be considered when utilizing high level of lupin in aquaculture feeds. Lupin meal is comparable nutritionally with soybean meal, it is more cost effective.

Abstract

The sedimentological aspects of the Mesjid River Estuary and its neighboring seas are revealed by various analytical approaches; i.e. mechanical grain size analysis, ignition loss method, metallic element analysis and sand grain composition analysis. The estuary area is characterized by fine sediments (very fine sand to very fine silt). Based on the relation between the character of bottom sediments and the environmental condition, the the Mesjid River Estuary and its Environs is divided into the following three areas: 1) The western part of the study area characterized by rather coarse-grained sediments and low mud content　under the influence of longshore current and poorly sorted sediments supplied by the Mesjid River, 2) The southern part of the study area characterized by coarse-grained sediments under the influence of strong tidal currents, 3) The northern and eastern parts of  the study area characterized by fine-grained sediments and high mud content under conditions of sea water masses. The texture and organic matter content of the sediments play important role on the growth of the mangrove which thrive along the coast of the study area.

Abstract

Coral reefs are the most diverse marine ecosystems; however, little is known about their microbialdiversity in these ecosystems. The present study is aimed at investigating the general insights into thediversity of the bacterial community associated with the coral Galaxea fascicularis. A culture collectionof 45 bacteria associated with coral G. fascicularis from Ujung Kulon, Indonesia was established byplating on Zobell’s 2214E. Isolates were screened by means of RLFP and sequencing of representative16S rDNAs. Using the restriction enzyme HaeIII, isolates were classified into 8 pattern group. Thesequence results indicated that a high diversity of bacterial phylotypes was present within the coralGalaxea fascicularis. In general, there are three major groups of bacteria: (i) members of the division Firmicutes , (ii) Actinobacteria, and (iii) γ-proteobacteria. Phylogenetic data on microbial communitycomposition in coral G. fascicularis will help in the rational selection of culture conditions to improvethe diversity of bacteria and the knowledge on the physiological, biochemical, genetic, and molecularproperties of coral bacteria.

Abstract

Coprostanol has been proposed as an indicator of domestic (sewage) pollution by researchers because constraint of using coliform bacteria as the indicators of domestic pollution in the environment with high environmental stress, such as urban coastal waters. Increasing the volume of industrial wastes, toxic and heated, the changing of water salinity from low (freshwater) to high (sea water), and  decreasing of dissolved oxygen (DO) in the waters, are the constrain factors of bacteria growth. How ever, all the researches have been done in the temperate (high latitude) regions. Information existence of coprostanol in tropical region, especially in Indonesia is still very poor. To understand the existence of coprostanol in the sediments, one core sediment sample (60 cm) was collected from Semarang coastal water adjacent to Banjir Kanal Timur which is the main drainage system of the East Semarang municipal district in Central Java by using a small gravity corer in July 2001. The core sediment sample was divided into 12 sections (5 cm each) for analyzing the concentration of coprostanol, grain size, and TOC. The result shows that coprostanol could be detected in all sample sections (vary from 1.06 to 2.94 mg/g). Coprostanol has significant positive correlation with TOC, but not significant with grain size. Coprostanol has very significant negative correlation with the depth of core. Based on the potency of sedimentation rate analysis on Banjir Kanal Timur Semarang coastal waters (0.35 cm/month), the 60 cm core sediment was predicted as a result of 14 –16 year sedimentation. All of these facts show that coprostanol has an excellent persistence in the sediment of tropical environment, and reflect that coprostanol has a potency as an alternative indicator of domestic waste pollution in urban tropical coastal waters. age��G'p� x� environments by Indonesian scientists. This is mainly because of the lack of knowledge in the field of deep-sea microbiology in Indonesia.

Abstract

Coral reef is a productive ecosystem with high biodiversity in the sea and being targeted to find a useful bioactive compound. However, the serious problem in development of bioactive compounds from marine invertebrate is the supply problem, because to get a small amounts of active compounds a massive numbers of sea organisms are needed. Tunicate is an animal in coral reef ecosystem that produces many bioactive compounds with pharmacological activities, such as, antibacterial, antitumor, and anticancer compounds. It has been reported that bacterial symbionts of coral reef invertebrates may synthesize the same compounds as the host. The purposes of this research are to isolate and to identify microbes which have antibacterial activity against MDR bacteria based PCR 16S rRNA and to detect the existence of  PKS and NRPS biosynthetic gene fragments from tunicate bacteria of Didemnum molle. Out of 15 bacterial isolates, one isolate showed antibacterial potential against Escherichia coli and Staphylococcus sp. Molecular identification result showed that TS2A5 bacterium has a homology of 99 % with Virgibacillus sp. strain GSP17 16S ribosomal RNA gene. This isolate was also capable of amplifying  NRPS gene fragment.

Abstract

The aims of study were to identify the potency and nutritional values of local raw materials available in Central java, and to develop the mud crab feed using selected raw materials for its deffatening culture. The potency level of local raw materials was determined by using secondary data available in relevant technical institution e.g. Agriculture Department, Fisheries Bureau and followed by direct site survey in the production centre of agriculture and fisheries by catch in Central Java, i.e  Pekalongan, Kendal, Semarang, Jepara, Pati and Rembang. Data obtained were analyzed descriptively to determine the resource of the potentials of local raw materials and followed by determining their nutritional values, profile and availability of assential amino acids (EAA) and essential fatty acids (EFA), using standard method available. The results indicated that the local raw materials for protein sources are found in abundance in Central Java throughout the year with relatively cheap price i.e: trash fish, mysid, squid, blood meals, worm-meals and shrimp head-meals (animal protein) and saga, soybeans (plant protein). The protein level of selected raw materials were high (41.15% – 80.35%) and the highest level was found in blood meal and followed by squid, trash fish and shrimp head meals. The selected raw materials, generally contains 10 essential amino acids (Arginine, lysine, histidine, phenylalanine, leucine, isoleucine, methionine, valine, threonine, and trypthophane) and a long chain of EFA (n-3 HUFA) and (n-6 HUFA) which are required by mud crab for their growth. The selected local raw materials are therefore nutritionally suitable for mud crab feed development in Central Java.

Abstract

Many empirical researches on urban growth have been carried out in megapolitan cities like Jakarta, and Surabaya. Most theoretical studies in this particular problem have been concerned about the expanding urban areas. This study differs firstly, concerning urban growth in a coastal city named Semarang, and secondly using superimposed and descriptive analysis based on old city-map and field survey data. Base on mapping analysis and field survey, Semarang urban fringe areas indicated dualistic characteristics, a mixing of formal and informal, planned and un-planned settlements. Most of them are incrementally spreading, mixed and growth simultaneously. Semarang as a port and ex- Dutch colonial city just has been on the earlier stages of spatial and structural evolution. This stage has been characterized as “spill over and specialization” occurred in fringe areas and it would lead to poly-centric metropolis. New urban infrastructure network has a contribution to the mono-centric fragmenting and metamorphosing into a poly-centric metropolis. The main activities at urban core have been move sporadically and incrementally to fringe area. Middle class migrated out of the city centre into sprawl settlements on the fringe areas. The role of central city decline while fringe areas increase. These conditions raise complicated social problems.

Abstract

The coral reef is the most productive marine ecosystem in coastal waters. The primary productivity may reach up to more than 10 kg C/m2/year. This resulted in a high number of fisheries production, such as fishes, shrimps, lobster, mollusc (shellfish), turtle, and others.  Unfortunately, this condition has already suffered from non-sustainable human use including destructive fishing practices (bombing and cyanide), coral mining, over fishing, settlement pollution and uncontrolled tourism development. These affected the production of those fisheries resources in coral reefs. In order to manage those resources, such alternative to destructive use need to be studied. This paper reports alternatives to destructive fishing practices  on coral reefs. The study had been carried out at Taka Bonerate Marine National Park, the District of Selayar, South Sulawesi province,  for about 3 weeks, 7-26 November 2000.  Survey method was used during the study.  The data were collected using Participatory Rapid Appraisal (PRA)’s method, with members of fisher group as the participants. Three kinds of reef fish groups are identified at the Taka Bonerate Islands waters, i.e. major group, target group, and indicator group. These include ornamental and consumption fishes.  These were caught with several fishing gears, while some of them are identified as destructive fishing practices, e.g. bomb, cyanide fishing. However, some of them can be recommended as sustainable fishing technologies, i.e. (1) pancing cumi-cumi, (2) pancing tonda, and (3) samba/kulambi.
