Rainbow fish (Melanoptaenia spp.) originated from Sungai Gelap of Papua. The objective of this experiment was to know the fecundity, hatching rate and the rate of embryogenesis. Total of 50 male and female broodstock measuring 10–15 cm reared in closed recirculating water system in concrete tank until their gonad matured. One pair composed of one male and two female’s of matured fish was transferred to 1 x 1 x 0.5 m³ concrete tank for pair breeding, the fish was sheltered with water hyacinth. Released eggs were observed in the morning and in the afternoon daily. Eggs were categorized into fertile and infertile. Some 25 eggs were incubated in plastic baskets, and observed under microscope for their embryonic development stages. The results showed that rainbow fish from Sungai Gelap produced eggs (averages) 392 per female; fertility rate was 93.74%; average hatching rate was 87.36%, and the fertilized eggs were hatched approximately 5 days incubation.

The technology of fish germ cell transplantation had been established to create broodstock systems by which a target offspring can be produced from a surrogate parent. Donor cell for transplantation is derived from transgenic fish carrying green fluorescent protein gene functions as a marker to distinguish the donor from recipient cell. In this study, an alternative technique was developed for identifying gouramy-derived donor cell and Nile tilapia as recipient by PCR amplification method using growth hormone (GH) gene as a molecular marker. Specific primer for GH gouramy was designed by using Genetyx version 7 software. ß-actin gene was used as an internal control of DNA loading. The result showed that a specific PCR amplification product of 340 in length was obtained when the DNA template was from gouramy, while no PCR product from Nile tilapia. The minimum concentration of genomic DNA of gouramy mixed with a 700 ng/µl of Nile tilapia that could be detected by PCR was 1 ng/µl. Thus, PCR method with specific GH primer may be useful to detect the incorporation of donor cell in recipient gonad towards development of surrogate broodstock technology.

Biodiversity, species assemblages, ooze sediment, Myll Lakes
Phytoplanktons are primary producer, which determine the waters productivity. The assemblages of phytoplankton in the lake varied spatially and temporally as a result of nutrient concentration, some physical and chemical factors. However, the assemblage of phytoplankton in the lake was not well documented. The overall aim of the study was to count and identify phytoplankton taxa and to examine assemblages at location with and without ooze, and to relate the presence/absence of ooze to phytoplankton abundance and assemblages. The samples were collected from Myall Lakes, NSW Australia. The data were analysed using multivariate analysis to determine assemblages of phytoplankton amongst location. Furthermore, univariate analysis was used to examine how the water quality was in particular presence/absence of ooze affected to phytoplankton abundance. The hypothesis being tested was: (1) phytoplankton assemblages vary spatially in Myall Lake due to varying water quality characteristics, including presence of ooze, (2) there was a significant difference of phytoplankton abundances between locations due to presence/absence of ooze.In both instance the hypothesis on this study was accepted. There was a significant different not only phytoplankton assemblages but also phytoplankton abundance within locations. It concluded that the phytoplankton varied spatially in those locations. Presence/absence of ooze affects abundance of phytoplankton. However, further study was needed to conduct in particular to determine certain aspects which affect the assemblages and abundances of phytoplankton.

The increasing demand for freshwater resources generated by human population growth, urbanization, industrialization and irrigation will result in a decline or loss of freshwater fish such as Osteochilus spp. The aims of research were to analysis the population of Osteochilus spp in terms of abundance, longitudinal distribution and sex ratio and to determine environmental factors of river driven these populations. The research was carried out in upper part of Serayu River during wet season (January – March) and dry season (June - August) 2007. Fish was collected by using electro fishing and stratified random sampling was applied by dividing this river into five strata based on altitude. The result showed that the total abundances of Osteochilus spp. was 149 individuals, it was composed by of O. hasselti (47) with 8.30 – 24.35 cm and 11.20 – 198.70 g, O. microchephalus (101) with 11.35 – 25.21 cm and 17.9 – 206.5 g and O. kahajanensis (1) with 17.30 cm and 68.80 g. The size of population O hasselti and O. microchephalus gradually increased from 7 and 4 individuals in stratum A became 27 and 12 individuals in stratum D, and then increased up to 43 and 17 individuals in stratum E. The sex ratio of O. hasselti was 10:16 and O. microchephalus was 20:23. Both species were longitudinally distributed in Serayu River. It seems that the population of O. hasellti and O. microchephalus were more influenced by physical factors i.e. depth and current rather than chemical factors i.e. DO and pH of Serayu River.

Research was conducted to know the effect of salinity on the reduction of parasites in Gouramy (Osphronemus goramy). The Research was performed using completely Randomized design with 5 salinity treatments (water pond, water with salt concentration 0, 2, 4 dan 6 g/L) with 4 replications. The 5-7 cm of gouramy fingerling were reared as on treatments and the parasites were counted using skin scrapping dan wet mount methods. Observation was performed every 3 day for 15 days on parasite intensity, prevalence, mortality, symptoms and water quality.The result showed that several parasites including Trichodina sp., Apiosoma sp., Ichthyophthirius sp., Oodinium sp., dan Henneguya sp were observed. The highest intensity and prevalence was found in Trichodina sp. The Salinity and lenght administration were significantly decrease number parasites. Salinity treatments (2, 4 dan 6 g/L ) for 3 days could totally removing Trichodina sp. from fishes. Meanwhile the data of other parasite species were unsignificant due to the low level of its intensity and prevalence. Salinity administration in level 6 g/L could reduce mortality.

Polychaete worm is an important zoobenthos at shrimp culture system, however since there is no any culture of these worm in Indonesia, then all the worm biomass collected from their natural habitat. It raised some concern about their safety because polychaete worm might be get infected and will realistic as a pathway for virus to attack shrimp broodstock in the hatchery. Fresh polychaete worms (1 g wet) used as a test organisms were caught from pond area in Semat region, Jepara. The step of these experiment are identification of WSSV infection at polychaete worms in wild with PCR analysis, visual, microscope and histology observation. Followed by challenge test of polychaete worm with WSSV, and WSSV infectivity study at black tiger shrimp broodstock. It seen, from the experiment, that using two different PCR methods, OIE (2006) and Nugen kit, and also histology analysis showing no WSSV infection in polychaete worms. However, from further experiment showing that polychaete worm challenge by WSSV have already got severely stress due to WSSV inocculum treatment, but the level of infection is still very low so that can not detect by PCR. Shrimp broodstock that have already fed with WSSV-contaminated polychaete worms for 1 week, based on clinical signs seems to get infected by WSSV, even the infectivity level is still very low. It concluded that polychaete worm can be a vector for WSSV in pond.

Pesticides and heavy metal are the major contributor for environmental pollution and have been spread out widely in aquatic environments. Daphnia sp. is a zooplankton that mostly used to detect aquatic pollution. The aim of this research was to study the effect of exposuring different concentration of heavy metal (Pb and Cd) and pesticides (diazionin) to the sex ratio offspring of Daphnia sp. The experiment composed of three kind of treatments (Cd, Pb and diazinon), each consist of 5 treatments namely 25%, 50%, 75%, 100% and 0% as control, and 4 replications. The data was analyzed with Kruskal Walace. If there was any different in each treatment, then was analyzed with Duncan Double Gap Test and linear regression. The research showed that exposuring Cd, Pb and diazinon with different concentration to the Daphnia sp. during 96 hours could increase the percentage male offspring of Daphnia sp. Concentration of Pb, Cd and peticides gave positive correlation to the sex ratio offspring of Daphnia sp. Further research was needed to know the practical technology using sex ratio offspring of Daphnia sp. to detect the level of pollution.

Market price of coral trout grouper was increasing by the color performance of fish. Beta-carotene diet was proposed to escalate pigmentation of coral trout grouper. Red fruit oil (Pandanus conoideus, Lam) which known as potential beta-carotene source was used in coral trout diets. The dosage of 5, 2.5 and 0 ml were supplemented to the every kilogram of pellet fed as a treatment in this observation during three-month period. Three hundred and fifty juveniles with initial total length 14.28±0.2 cm and 43.41±2.62 g of body weight were stocked in fiberglass tank of 5m³ seawater. Growth data were collected monthly, while color performance was taken by digital photography at the end of observation and analyzed by "Microsoft Adobe Photoshop 8". Carotene contents in the diets and fish body result showed that the Pandanus conoideus oil has role in increasing performance of coral trout with more bright color; five ml dosage gave the best growth performance with 35.57% and 185% for total length and body weight respectively, with 90% survival rate and 1.2 feed conversion ratios.

An attempt for diagnosis iridovirus infection at seed coral grouper Fish age sand around 60 days shows symptom as no eating, populating in basin base, colour turn darken, and here in after death. Disease detection of the showing symptom seed that has not generated death is observed based on pathological anatomy and viral detection with PCR-probe. Disease detection also conducted to seed after showing symptom and generated high death. Detection based on pathological anatomy result many "giant cells" from spleen organ. Disease detection based on PCR-probe of seed which has not died yield thin positive band of iridovirus, while observation of death seed yields high crystal clear positive band of iridovirus at 570bp.

The aims of this research were to evaluate the eficacy of intra- and extracellular products vaccines of Aeromonas hydrophila to control Motile Aeromonas Septicemia (MAS) in catfish (Clarias sp.). Catfish with 10-13 cm of total length were used for the experiment with three treatments in five replicates. The treatments were vaccinations with (1) A: intracellular product of A. hydrophila; (2) B: extracellular product of A. hydrophila; (3) without vaccination (control). Vaccination was conducted by intramuscular injection of 5 µg protein/fish (each fish was injected with 0.1 ml of vaccine). Booster was conducted one week after vaccination. The challenge test was conducted two weeks after booster. The results showed that the survival rate, Relative Percent Survival (RPS), and antibody titer of A treatment was significantly different (PA. hydrophila (A treatment) reached 85.33 and 82.26%, respectively. The highest antibody titer was 1843.2 which was obtained by the A treatment. The results suggested that intracellular product vaccine of A. hydrophila was more effective than extracellular product vaccine.

juvenile common carp, single cell protein
This experiment was conducted to determine the effect of dietary single cell protein as substitution for fish meal in fish diets. Five isonitrogenous (38% crude protein) and isocaloric (3,040 kcal digestible energy/kg diet) practical diets, namely diets A, B, C, D and E with different levels of single cell protein were fed to juvenile common carp (Cyprinus carpio). Twenty juveniles/aquarium with an initial weight of 1.20±0.11 g per individual were used in this experiment. Fish were cultivated in aquarium of 60 l capacity under standardized conditions at 26±10 C. The aquaria assigned to 5 treatments were arranged in triplicates. Diet A contained low dosage of single cell protein (0 g /100 g diet), while diets B (9.8 g /100 g diet), C (19.5 g /100 g diet), D (29.3 g /100 g diet), and diet E (39.5 g /100 g diet ), combined respectively with 39.5 g fish meal/100 g diet (diet A), 29.3 g fish meal/100 g (diet B), 19.5 g fish meal/100 g diet (diet C), 9.8 g fish meal/100 g diet (diet D), and 0 g fish meal/100 g diet (diet E). Fish were fed ad satiation for 45 days using these diets. The dietary with different level of single cell protein affected growth rate and feed efficiency. Fish fed on diet 39.5 g fish meal/100 g (diet A) produced the highest growth rate (1.15±0.267%) and feed efficiency (61.68±9.89%). Growth rate and feed efficiency decreased synchronously with increases in single cell protein in the fish diets. Lysine and tryptophan were higher in single cell protein than in fish meal; whereas arginine, histidine, isoleucine, leucine, methionine, phenylalainine, threonine and valine were lower in single cell protein. On the other hand, fish fed on experimental diets did not show any significance differences in the survival rate.

Genetic variations of marble groupers, Epinephelus polypekhadion were evaluated to know genetic performance of fish to support fish seed production. Fifty fish samples from three locations i.e. West Nusa Tenggara, South Sulawesi and East Java were collected for analysis. Genetic analysis has been examined through allozyme electrophoresis by using 11 enzymes (ADH, GPI, SDH, IDH, LDH, ME, PGM, 6PGD, MPI, SP, EST). The result showed that 16 loci were detected, and three of them were polymorphism enzymes namely Isocitric dehydrogenase (IDH*), Glucose Phosphate Isomerase (GPI-1*) and Esterase (EST-2*). One locus (EST-2) was polymorphic in the East Java and West Nusa Tenggara populations and three loci (EST-2, GPI-1 and IDH) were polymorphic in the South Sulawesi population. The heterozygosity ranged from 0.007 to 0.034. Rogers genetic distance between population pairs were ranged from 0.005 to 0.012 (average = 0.009). Differences between genetic populations were significant (P<0.05). East Java and West Nusa Tenggara populations have same gene pool.

The aims of this research were to determine the population parameters of hairtails (Trichiurus sp.) and the potential use of fish parasite (Anisakis sp.) for its stock assessment. Fishery survey was conducted at southern coast of Cilacap, Central Java on September to October 2004. Total length and weight of 527 fish samples were measured in five periods during the field survey and 30 samples were collected randomly for further observation to analyze the Anasakis sp., sex ratio, and gonad maturity. The average length of catched fish was ranged between 62 to 70 cm and weight was 200 to 250 g. The length-weight (L-W) relationship indicated positive allometric growth (b=3.6076). Sex ratio was balance at 1:1 with gonad maturity range between I to IV for female and I to III for male. Anisakis sp. were found as endoparasite and potentially used as biological tags for fish stock assessment such as migration pattern and feeding habit.

Epinephelus fuscoguttatus, floating net cages, fish farmer’s attitude, production risk
This study was aimed to investigate fish farmer’s attitude on production risk of Epinephelus fuscoguttatus growing in floating net cages, and to evaluate the impact of input usage on the production risk. The production risk explicitly assumed, reflected in the variability of E. fuscoguttatus production.The study used the case of fish farmer’s production of grouper growth out in floating net cages in Lampung Gulf, Lampung Province as an analysis unit. The respondent of fish farmers were obtained by census method.The analysis result suggested that the fish farmers were risk-averters toward fish seed, fish feed and human labor input. It also appeared that fish seed and fish feed were risk-inducing inputs while the amount of human labour was a risk-reducing input. Fish farmer’s attitude that avoid of the usage of human labour, more considered by decreased effort efficiency which was affected by increasing the amount of human labor whereas production level tend to remained or lower. However by the level domination of adequate E. fuscoguttatus culture technique which owned by the human labour, the usage of human labor could be act as “risk-reducing”.

This research aimed to understand the adoption level of insulation palka for handling fresh fish, and the relationship between internal-external characteristics of fisherman with technological adoption level. The research was located in Pelabuhanratu, Sukabumi which was one of the locations for the introduction of insulation palka by Fisheries Research and Development Centre. Samples were collected by purposive sampling method, with fisherman using insulation palka to handle fresh fish as respondent. Data were analysed by descriptive analysis and non parametric (Spearman correlation) test. The result showed that fisherman in Pelabuhanratu had a high motivation to adopt insulation palka technology indicated by application of recommended technological packages. The relationship test indicated that formal education factor, family income, numbers of labours in family, reason of using insulation palka, cosmopolitan, interaction with extension agent and decision making type should be paid attention related to every effort to introduce the similar technology. Besides, external characteristics which should be paid attention were member of fisherman group, availability of infrastructure, enforcement of society leader, institution support, capital source, marketing, and culture value.

fishing boat, fishing gear, fisherman, management region, productivity
Fisheries productivity is defined as a comparison of production to fishing effort.The Fishing effort can be the number of fishers, fishing boats or fishing gears. This paper was developed from analysis of Indonesia Fisheries Statistic data in the period of 1990-2001 at 9 regions of fishery management in Indonesia. It was assumed that the catch by fisherman in each region will be landed at the same region. The results showed that productivity level of fisherman was lowest at WPP-9 (Indian Ocean) with a value 1,2 ton per year (an average 100 kg per month per fisher). The highest productivity of fisherman reached 3.1 ton in 1999 at WPP-5 (Sulawesi Sea and Tomini Gulf). The productivity of fishing boat was ranged from 7.8 ton to 16.4 ton per year per fishing boat. Then the productivity of gear was from 5,0 ton per gear per year to 13,5 ton per gear per year. From this result, it can be predicted that the distribution of fishing gear, fishing boat and fisherman in 9-WPP was not equally proportional. For sustainability life of the fisheries, it need a policy which may increase to economic benefit of fisherman and fishing activity.

bait, collapsible fish trap, reef fishing method
The aim of this research was to know the effectiveness of the trap which was modified and redesigned from its original. The research was conducted in the water of Baa, Rotendao district, East Nusa Tenggara Province. The trap was operated for 3 months started from August to November 2004 by using three types of baits. Fishes were collected from the trap every 2-3 days immersion by pulling up the trap on board. There were 69 individuals fishes in one trap representing 11 families and 15 species. Most fish species were highly economic values and was dominated by snappers (Lutjanidae) and groupers (Serranidae).
The fish size were ranging from 17 to 29 cm of tolat lenght (TL). There was no significant difference between bait used on the catch (p>0.05) suggesting that bait may not be required anymore on this specific reef fishing methods. It is realized that further studies may be required, however in the mean time, this gear may provide an alternative method for small scale reef fishing.

giant freshwater prawn (Macrobrachium rosenbergii), larvae, L-ascorbyl-2-monophosphate-magnesium, metamorphose
The aim of this study was to improve the production homogeneity of freshwater prawn post larva by the addition of L-ascorbyl-2-monophosphate-Mg (AMP-Mg) in the water during rearing period. AMP-Mg was given to the water every three days with different concentrations of 0; 0.5; 1.0; and 1.5 mg/l. The density of larvae was 50 larvae/l. Larvae were fed Artemia and egg custard during rearing period. The results showed that AMP-Mg did not significantly influence larval metamorphose rate, post larvae percentage, and survival rate of prawn. However, AMP-Mg addition could improve homogeneity of post larvae production. The optimum AMP-Mg concentration was 0.5 mg/l.

osmoregulation, phenol, tiger prawn
Phenol represents nerve poison which able to cause paralysis due to the damage on fat tissue of nerve. In crustacean like tiger prawn, the damage on nervous system disturbs molting and osmoregulation activity, because both of those activities related to neuroendocrine system under control of center nervous system. This research was done to : (1) study the effect of various phenol concentration in culture medium to hemolymph osmolarity and osmotic work level of tiger prawn, (2) determine Low Observable Effect Concentration (LOEC) and No Observable Effect Concentration (NOEC) of phenol to hemolymph osmolarity and osmotic work level of the tiger prawn.The results showed that phenol has a significant effect on decreasing hemolymph osmolarity and increasing osmotic work level of tiger prawn. Osmolarity and osmotic work level respon pattern of the prawn to various phenol concentration is linear regression equation. NOEC and LOEC to the hemolymph osmolarity and the osmotic work level of the prawn are 0 to 2.08 mg/l and 2.08 mg/l, respectively.

The main objectives of this research were to isolate, purify and determine the immunogenicity of the outer membrane protein of V. alginolyticus. The outer membrane protein was isolated by sonication, sodium dodecyl sulphate-polyacrylamide agarose gel electrophoresis (SDS-PAGE) and purified by electroelusion method. Four outer membrane proteins were obtained: namely 32.0; 37.83; 64.13 and 73.43 kDa. Its immunogenicity in grouper Epinephelus fuscoguttatus was compared to that of bacterin of the same isolate. The immunogenicity test was conducted by intra peritoneal injection method. Each protein was dissolved in sterile Phospate Buffer Saline (PBS) and Freund’s Complete Adjuvant (FCA) (1:1) and injected 5 µg/ fish (fish weight 10-15 g). Bacterin (106, 107 and 108 cells/ml) was prepared in the same manner and injected at dosage of 0,2 ml/fish. Control fish were injected with 0.2 ml sterile PBS (pH 7.2). Booster was done a week later by injecting protein or bacterin with the Freund’s Incomplete Adjuvant (FIA). The agglutination test of antibody produced recognized cell surface protein of the whole cell of V. alginolyticus. Outer membrane protein 73.43 kDa was more immunogenic than the rest of proteins and bacterin, based on agglutinating antibodi titer.

Objectives of this study were to find out the protein of Aeromonas hydrophila for vaccine, and to evaluate the efficacy of the protein to control Motile Aeromonas Septicemia (MAS) in catfish (Pangasius hypophthalamus). A. hydrophila was isolated from the kidney of diseased catfish. The isolate was cultured, sonicated and sentrifuged into cell-free extract and debris. The protein in the cell-free extract was precipitated with ammonium sulphate, dialized, then fractionated by gel filtration column chromatography on Sephadex G150.The concentration of protein were estimated by spectrophotometer at 280 nm. Fractions obtained from the gel filtration with high concentration of protein were analized by sodium dodocyl sulphate-polyachrylamide gel electrophoresis (SDS-PAGE). The protein bands obtained from SDS-PAGE with molecular weight more than 10 kDa were tested for immunogenicity to mice. Futhermore, the most immunogenic protein was used for fish vaccination. The vaccinated and unvaccinated fishes were chalenged with A. hydrophila.The results indicated that vaccination with the protein significantly increased (P<0.01) the antibody titer either in mice or catfish. Relative Percent Survival of catfish vaccinated with the protein at 5; 7.5; and 10 µg/fish were 61.54%, 80.77% and 76.92%, respectively. The optimum dose of vaccine was 8.33 µg/fish with maximum RPS of 82.05%.

An active surveillance of infectious myonecrosis virus (IMNV) in pond-cultured white shrimp (Litopenaeus vannamei) was conducted to determine the status of this disease. Samples of white shrimp (L. vannamei) were taken from ponds in East Java and Bali using proportional sampling. The sample was subjected to IMNV detection with Polymerase Chain Reaction (PCR) method and confirmed with histopathology. Results of this study showed that IMNV was found in shrimp samples from Kapongan, Situbondo district with the prevalence of 11,1%. Meanwhile, samples from other districts in East Java and Bali had no IMNV disease during this study. There is no treatment for viral disease in shrimp culture. Therefore, control of movement of live shrimp and application of biosecurity-area based should be more implemented among the shrimp culture area.

body composition, L-carnitine, muscular lipid, Pangasius hypopthalmus
This study was conducted to investigate the effect of dietary L-carnitine level on muscular lipid and body composition of asian catfish (Pangasius hypopthalmus). Four isoprotein and isocaloric diets with different levels of L-carnitine, 0.00% (diet K), 0.10% (diet A), 0.18% (diet B), and 0.29% (diet C) were applied in this experiment. Ten fishes with initial body weight of 35.86 ± 1.54 g were cultivated in each aquarium (water volume 60 l) for 50 days. Fishes were fed three times daily at satiation. The results showed that L-carnitine in the liver increased by increasing dietary L-carnitine level. While increasing dietary L-carnitine until 0.18% decreased content of lipid in the liver, but excessive dose of dietary L-carnitine increased content of lipid in the liver. It was further observed that L-carnitine in the diets reduced the muscular lipid content from 32.35 to 7.51% dry weight, but had no effect on body composition.

Cilala reservoir, limnological status
The purpose of this research was to study the limnological status of Cilala reservoir, based on physical, chemical, and biological parameters. The observation comprised some morphometric of surface and vertical dimension, water quality measurements, plankton community structure, and primary productivity. Based on some morphometric condition, Cilala reservoir has a high potention of biological productivity, but the area of lake begins narrowing. The physical and chemical characteristic showed that Cilala reservoir was still in good condition. The condition of Total Suspended Solid (TSS) at inlet and the water debit of outlet showed that the waters has a relatively high potention of sedimentation that lead to a shallowing condition. There were found 95 genus of phytoplankton from seven classes (Bacillariophyceae, Chlorophyceae, Cyanophyceae, Chrysophyceae, Euglenophyceae, Pyrrophyceae, and Xanthophyceae). It was also found four major groups of zooplankton, i.e. Rotifera, Copepoda, Cladocera, and Protozoa. Although the primary productivity was relatively low, based on orthophosphate, chlorophyll-a, and Nygaard Index, the water was in mesotrophic-eutrophic status. As a whole, Cilala reservoir was still appropriate for fisheries activities.

The purpose of this study was to observe the effect of Eucheuma cottonii consumption to the diabetic blood glucose level. Study on reducing blood glucose by consuming seaweed E. cottonii was conducted using male wistar rat (Ratus norvegicus). Rats were made to a hyperglycemic condition by aloxan injection before given ransom contains of 5, 10, 15, 20% (w/w) E. cottonii, standard ransom (negative control), and parental glibenklamid (positive control). The result showed that standard ransom was not able to reduce blood glucose from hyperglycemic to normal level, while ransoms with E. cottonii were able to do so. The higher E. cottonii seaweed level in the ransom had the higher capacity to decrease blood glucose level. The ransom with 20 and 15% E. cottonii were able to reduce blood glucose in 18 and 21 days, respectively.This treatment has the same ability as glibenklamid medicine which also reduced blood glucose to normal level in 18 days. Ransom with 5 and 10% E. cottonii were also able to reduce blood glucose level but the normal blood glucose level could not be achieved until 21st day.

One of the preservative agents that was claimed having bactericidal effect is glyroxyl. This study was aimed to observe the effect of glyroxyl on carp’s (Cyprinus carpio) shelf life. Factorial design was used in this experiment with 9 treatments in triplicates. The fish was immersed in glyroxyl solution at concentrations of 0 (control), 0.1, 0.3 and 0.5% (w/v) for 5 min. Following immersion, fish was drained and kept in plastic bucket at ambient temperature. Sampling was done at 0, 12 and 24 h storage and analysis was carried out organoleptically, chemically (TVB) and microbiologically (TPC, Enterobacter). Results showed that organoleptically, chemically and microbiologically, there were no significant different on spoilage inhibition of glyroxyl compared to control. Similar to control, glyroxyl was able to prevent spoilage of carp fish only up to 12 h. The fish was rejected by panelists after 12 h of storage. The TVB value and bacterial counts, including Enterobacter, also increased sharply after that time.

The objective of this research was to know protein and energy digestibilities of marine yeast, as substitution for soybean meal in the ration of patin (Pangasius sp.) and humpback grouper (Cromileptes altivelis).This experiment used completely randomized design with four treatments in triplicates. The treatments were R1 (100% animal protein); R2 (90% animal protein+10% soybean meal); R3 (90% animal protein+5% soybean meal+5% marine yeast); and R4 (90% animal protein+10% marine yeast). The digestibility of protein in ration of patin was significantly different (P<0.01). Marine yeast in patin ration also improved the growth rate (P<0.05). Substitution soybean meal with marine yeast in ration of patin was not influence the energy digestibility and feed conversion ratio (FCR) (P>0.05). Rations with 5 and 10% of marine yeast improved energy and protein digestibility, growth rate and decreased the FCR. Digestibilities of protein and energy, growth rate and FCR in humpback grouper were significantly different (P<0.01) among treatments. Marine yeast in ration of humpback grouper increased digestibilities of protein and energy. However, substitution of animal protein with soybean meal and marine yeast decreased growth rate and improve FRC in humpback grouper.

Pengaruh Salinitas dan Kondisi Fertilisasi terhadap Persentase Larva Normal pada Kerang Bakau Polymesoda erosa Solander (1786)
Gimin, Ricky
Polymesoda erosa, salinity, fertilization, D-larvae
The mangrove clam (Polymesoda erosa) is edible bivalve and one of potential candidate for aquaculture. Availability of its hatchery technique is important for development of its aquaculture. The objective of this study was to determine the optimum salinity and fertilization factors for the production of normal larvae. Fertilized eggs at density of 10 eggs/ml were incubated under seven salinities, i.e., 0, 5, 10, 15, 20, 25 and 30 ppt at room temperature (26±1°C). The highest percentage of 48 hr normal D-larvae occurred at 20 ppt. The percentage dropped significantly if salinity was below 10 ppt or more than 25 ppt. In other experiments to develop fertilization protocols for this species, the effects of spermatozoa-to-ovocyte ratio, age of gametes, and stocking density of eggs were assessed individually to determine the optimum ratio, age and density for the highest percentage of normal D-larvae. Ten sperms-to-egg ratios, i.e., 5, 10, 50, 102, 5x102, 103, 5x103, 104, 5x104 and 105 at density of 10 eggs/ml, were tested. The highest percentage of normal D-larvae occurred within the range of 5x102 to 5x103 sperms per egg. Significantly low percentages were obtained at treatments below 100 or more than 104 sperms per egg. In the experiment of gamete age, sperms and eggs were mixed for fertilization at different times, i.e., 30 minutes, 45 minutes, 60 minutes, 120 minutes and 180 minutes, after spawning. Freshly spawned sperms and eggs of less than 60 minutes gave the best percentage. When the fertilized eggs were incubated at different densities, i.e., 10, 20, 30, 40, 50, 100 and 200 eggs/ml, the densities up to 50 eggs/ml gave maximum results.

sperm storage, sperm motility, fertility, nilem (Osteochilus hasselti C.V.)
The success of induced breeding relies on the availability of viable sperm and eggs. Meanwhile information on viability of post-stripped sperm of the nilem is still limited. This experimental study was conducted to find out the duration of sperm storage that maintains sperm viability. The nilem’s milt was diluted in Ringer solution at 0, 10, 100 and 1,000 dilution and kept in the refrigerator (4°C) for 3, 6 and 9 days. The sperm viability was assessed by its motility, progressivity and ability to fertilize fresh eggs. The results showed that the sperm were immotile in either undiluted or diluted in Ringer solution. Upon activation by diluting in water, the sperm of the control groups as well as the tested groups showed a high motility (>70%) and highly progressive (>3). The sperm were capable to fertilize eggs as indicated by a high fertilization rate of more than 90%. The highest hatching rate (HR) was produced by the control groups while HR of milt stored for 3, 6 and 9 days were 60%, 1% and 0%, respectively. Low HR produced by milt stored for 6 and 9 days was resulted from a high proportion of abnormal embryos which led to their mortality around gastrula stage. It could be concluded that the viability of the nilem’s sperm could be diluted in Ringer solution and kept in the refrigerator as long as for 3 days.

Total of 31 species of echinoderms, consisted of 10 species holothuroidea, 9 species of asteroidea, 6 species echinoidea and 6 species ophiuroidea have been found in the Tanjung Pai, Padaido-Biak Numfor. The sea cucumbers were relatively common in the sea grass-zone. Based on population density, the sea cucumber was the dominant group and their density was the highest, but their distributions were very scarce. Among the echinoderms found in this study, only sea cucumbers were exposed to the exploitation, since its local market price was still high. Further, the diversity and density of species found at Tanjung Pai were poorer compared to the other place in Indonesian waters, such as Derawan Islands of East Kalimantan

Murwantoko, Murwantoko
Detection, Loop-mediated isothermal amplification (LAMP), Pathogen, PCR
Polymerase chain reaction (PCR) is a method that amplifies DNA which have been widely used in molecular biology technique. Based on the PCR, many methods have been developed on isothermal condition and the useful one is loop-mediated isothermal amplification of DNA (LAMP). LAMP reaction employs a Bst DNA polymerase and a set of four specific primers that recognizes a total of six distinct sequences of the target DNA and produces amount of different size of DNA. Many advantages have been achieved in LAMP such as the simple equipment for reaction and observation, short time, highly specific and sensitive procedure. LAMP has been used as a tools for detection many pathogens for human, animals and plants. Some fish pathogens as parasites, bacteria and viruses have been detected by LAMP. The principles and application of LAMP method are discussed in this paper.

anesthetic, clove oil, Lates calcarifer, sea bass, transportation
The objective of this study was to determine the safety and efficacy of clove oil as an anesthetic in sea bass (Lates calcarifer) and the potential application of clove oil as anesthetic to facilitate the sea bass fry transportation. Acute toxicity test indicated the 24-hr LC50 value of clove oil in sea bass fry as 30 ppm with slope function of 1.079 (1.05 to 1.107). In efficacy test, fish were exposed to 5, 10, 15, 20 and 25 ppm of clove oil for 15 minutes. At 5 ppm, clove oil caused only sedation effect (partial loss of reaction to external stimuli) while at 20 ppm, fish entered anesthesia stage (failure to respond to external stimuli) within about 3 minutes. Fish recovered from a 15-min period of exposure in 20 ppm clove oil within less than 10 minutes following removal from the anesthetic solution. There was neither mortality nor abnormal behavior of fish during 15-min exposure of clove oil as well as during 7 days post recovery from anesthesia. The potential application of clove oil as an aid in the transport of sea bass fry in plastic bag was also investigated. At 5 ppm, clove oil could reduce activities of the fish without loss of equilibrium (sedation stage) during the 4 hour simulated transport at 50 fish per 1,000 ml sea water (15 ppt). At 20 ppm, clove oil caused loss of equilibrium in fish resulting in the anesthesia stage throughout the 4 hour period. However, there was no improvement on survival rate and fish behavior with the use of clove oil during and after this 4 hour transport. Simulated transport at 50 fish per 500 ml sea water (15 ppt) for 8 hour did show better significant survival rate with additional of 5 and 20 ppm clove oil. In both short and long term transport study, clove oil did show the benefit by reducing the fish activities judging from the reduction of oxygen consumption, ammonia and carbon dioxide levels. Addition of appropriate concentration of clove oil in transport water ensured that the fish would stay calm by reducing fish activity and therefore, prevented any drastic changes of water qualities.

This research was aimed to investigate the pathogenicity of Vibrio fluvialis 24SK in humpback grouper (Cromileptes altivelis) based on its Lethal Dosage 50 (LD50). V. fluvialis 24SK was isolated from ren of humpback grouper cultured in floating net cage at Brackishwater Aquaculture Development Center (BADC) Situbondo, with vibriosis signs. The bacterium was cultured in Tryptone Soy Broth (TSB) medium dissolved in trisalt solution (KCl, 0.75 g/l; MgSO4.7H2O; 14.2 g/l; NaCl, 18.4 g/l), incubated at 300C for 24 h. Infection was carried out by interperitoneal injection to humpback grouper (8-9 cm of total length) at 102, 104, 106, and 108 cfu/fish. Control fishes were injected with 0.2 ml trisalt solution. Disease sign and mortality of fishes were observed every eight hour for 40 days. LD50 was calculated based on Dragstedt Behrens method (Hubert, 1980). Result indicated that infection of the bacteria at 106 and 108 cfu/fish caused sub-acute disease signs, such as haemorhagic on operculum, base of fins (pinnae pectorales, pinnae abdominales, pinna analis), and also head and abdomen, while infection at 102 and 104 cfu/fish caused chronic disease signs, such as haemorhagic on fins base which was followed by necrotic on fins and skin tissue in prolonged time. Histopathologically, infection of the bacteria caused atrophy on the gills, infiltrations of lymphocyte, heterofel and plasma cell on the gills and fins base, vacuolar degeneration on the liver, and also present the bacteria colony on the fins base and intestine tissues. V. fluvialis 24SK has LD50 at (1,1±0,5)x107 cfu/fish.

Samples of yellowfin tuna (Thunnus albacares) were taken from three locations Bali, North Sulawesi and North Maluku. The glucose-6-phosphate isomerase (GPI) was analyzed from liver using allozyme electrophoresis method. Polymorphism of GPI enzyme was observed and four alleles (A, B ,C, D) were found in Bali population, three alleles (A,B,C) were found in North Maluku and North Sulawesi populations. Heterozygosity values, from Bali, North Maluku and North Sulawesi were 0.419; 0.417; 0.143 respectively. Genetic distance between North Sulawesi and North Maluku were 0.029, and with Bali population was 0.353. These results indicated that North Maluku and North Sulawesi population were not separate by geographic barrier, therefore genetic distance of both populations was closed. However, those populations were genetically separated to the Bali population might be due to major hydrological barrier.

Brachydanio rerio, fatty acid, reproductive performance
This experiment was conducted to determine the dietary n-3 fatty acid requirement for reproduction of broodstock zebrafish, Brachydanio rerio. Three isonitrogenous (39% crude protein) and isocaloric (3,260 kcal digestible energy/kg diet) practical diets, namely diets A, B, and C, with different levels of fatty acids were fed to zebrafish broodstock. The broodstock were cultivated in aquaria. Diet A contained low dosage of n-3 fatty acids (0.4%) and 2% n-6 fatty acids, while diets B and C contained 2% n-6 fatty acids, combined respectively with 1% and 1.5% n-3 fatty acids. Fish were fed ad satiation for 60 days using these diets. During feeding periode, gonade maturation stages were examined. The n-3 and n-6 fatty acids affected fecundity, fertilization rate, and hatching rate. On the other hand, fish fed on diets A, B, or C did not show any significance differences in the gonade somatic index and total Survival Rate (SR) of larvae produced. Fish fed on diet B produced the highest fecundity (616 eggs/g of fish), fertilization rate (94.6%), and hatching rate (93.8%). The total lipid content of eggs were significant, ranging from B (29.7%), C (23.7%), and A (16.1%). At a dosage of 2% n-6 fatty acids, zebrafish require 1% of dietary n-3 fatty acids in the diet for reproduction. Excess dosage of n-3 fatty acid in the diet adversely affected fecundity, fertilization rate, and hatching rate.

Baung (Mystus nemurus), Feed Conversion Ratio, Halquinol, Survival Rate
This research aimed to determine effect of halquinol addition as feed additive in artificial feed of baung (Mystus nemurus) seed. Some factor measured as indicators of the effect were growth rate, feed conversion ratio (FCR), survival rate and optimum dose of halquinol which resulted the best growth, feed conversion ratio (FCR) and survival rate. Baung fish seed (0,83 g of mean body weight) were used in this experiment. The seed were obtained from Freshwater Aquaculture Center (BBAT), Sukabumi,West Java. The test feed was commercial artificial feed powder which was pelleted. This research used Completely Random Design with 4 treatments in triplicates. The treatments were addition of halquinol in the feed with different concentration i.e.: A (0 mg/kg), B (12.5 mg/kg), C (25 mg/kg) and D(37.5 mg/kg). The result indicated that addition of halquinol in feed increased the growth rate and decreased feed conversion ratio, but did not affect the survival rate of baung seed. Addition of halquinol at 25 mg/kg feed gave the highest growth rate and lowest FCR.

Cherax quadricarinatus, growth, lime concentration
This research was conducted to determine the effect of lime (CaCO3) concentration on the availability of calcium in water and growth of Crayfish (Cherax quadricarinatus). Completely random design was used in the experiment that consisted of 4 treatments and 3 replications. Four treatments of lime concentration were 0, 50, 100, and 150 mg CaCO3/l. The research was conducted in Fisheries Research Station, Agriculture Faculty, Gadjah Mada University for 30 days. Ten Crayfish were reared in 60 cm x 40 cm x 50 cm aquarium in 60 l water. Crayfish were fed ad libitum with Tubifex tubifex. Calcium concentration on water, Crayfish growth, and water quality were observed every tenth days. The data of calcium concentration on water and Crayfish growth were analyzed with regression and correlation analysis at 95% confi dence level, whereas water quality analyzed descriptively. The research showed that there was correlation between lime concentration and its availability in the water. It showed that, more lime concentration resulted on higher calcium availability in water. Crayfish growth was relative faster on higher lime concentration.

arafura, crustacea, demersal fish
Arafura water is one of the centers of demersal fish and shrimp production in Indonesia. The exploitation of demersal fish and shrimp has grown quite rapidly, cause a declining trend in production from year to year. Besides the decline in production, changes also assumed to be occur in community and size structure of demersal fish and crustaceans. This research was conducted in the water of the Arafura in October to November 2006 to know the development of waters resources, particularly demersal fish and crustaceans (shrimp and crab). The result showed that there were changes in the composition of crustaceans, where commercial shrimp production decreased followed by an increase in types of non-commercial crustaceans (shrimp and crab). Family Portunidae (crabs) were very abundant and the most dominant species was Carybdis natator (98% of all crab species caught) with average catch rate of about 66 kg/hr. The size of demersal fish generally showed a declining trend. We observed in this research was much smaller than the previous year. Shrimp catches were dominated by krosok shrimp (Metapenaopsis sp.) which is a non-commercial shrimp.

bawean, plankton, spatial distribution
The presence of phytoplankton in the water is very important because it serves as a primary producer that is often used as an indicator of aquatic fertility. The objective of the research was to determine the species, density and spatial distribution of plankton in the Bawean waters, Gresik regency. Baruna Jaya VIII research vessel was used for sampling on 29-30 April 2009. Sampling locations were set up in two stations on the position of 06°05'S, 112°36'E and 06°05'S, 120°12'E, and water samples were taken at depths of 0m, 20m, 40m and 60m in each station. Water was collected using water samplers at amounts of 10 liters each depth, thenwas filtered using plankton net, and then preserved with formalin 4%. Identification of genus plankton was carried out in the laboratory.The results showed that there were 20 genus of phytoplankton and 38 genus of zooplankton which were spread outin each depth of the water column unevenly. Plankton density was as much as 2330 cells / liter, while the density of zooplankton was as much as 507 individuals / liter. The highest density of phytoplankton was found in the water column depth of 20 m, while the lowest was found at the depth of 60m. The highest density of zooplankton was found in the surface, then decreases as the depth of waters. The dominant genusof phytoplankton were Pleurosigma sp., then Rizosolenia sp., Skeletonema sp., and the least was Actinocyclus sp. The dominant species of zooplankton are Ceratium sp. then Tintinopaial sp., and nauplius sp.

Anguilla bicolor bicolor, chromosome, karyotype
The eels of genus Anguilla are catadromous, their juvenile grow in estuaries, rivers and lakes, and their spawning areas being offshore in the ocean. The eels of Anguilla have high economic potency due to good taste and high protein content. Eel Anguilla bicolor bicolor has been cultured but the seed was depending on the glass eels availability from nature. However, genetic study for Anguilla bicolor bicolor in Indonesia was limited. The aim of this research was to characterize the chromosome of eel Anguilla bicolor bicolor, to be used as a basic information for conservation and aquaculture development. Chromosome preparation was done by blood culture splash method. The results revealed that the diploid chromosomes (2n) of Anguilla bicolor bicolor was 38, classified as 34 (17 pairs) of metacentric and 4 (2 pairs) of submetacentric chromosomes. Displaying karyotype formula of 2n = 38 = 34m + 4 sm.
