Tiger shrimp diseases have occured in Indonesian shrimp ponds for more than two decades. In order to overcome this problem, five types of the RICA probiotic bacteria were tested in nine 250 m2 semi-intensive ponds of the Research and Development Institute for Coastal Aquaculture Marana Station. In the present study three different alternate use of the RICA probiotics were tested for tiger shrimp culture incompletely randomized design experiment. There were three treatments here namely: A) alternate use of probiotic bacteria RICA-1, RICA-2, RICA-3; B) alternate use of probiotic bacteria RICA-4, RICA-5, RICA-3, and C) control (without probiotic bacteria); each treatment were applied in three replications. The results showed that survival rate and production of tiger shrimp in treatment A (55.8% and 14.9 kg/pond) and B (52.7% and 16.7 kg/pond) were significantly better (P<0.05) than those of in control ponds (37.4% and 10.9 kg/pond). However, survival rate and production of tiger shrimp between treatment A and B were not significantly different (P>0.05). The average total bacteria population in the cultured water media of treatment A (4.32 x 104 cfu/mL) and B (5.18 x 104 cfu/mL) were relatively higher than control (1.46 x 104 cfu/mL). However the percentage ratio of Vibrio spp. and total bacteria population in the cultured water media of treatment A and B were relatively lower than control. The lower survival rate and production of tiger shrimp in control (C) compared to probiotic treatments (A and B) were not just affected by the increase of Vibrio spp. ratio, but also affected by the increase of total organic matter and nitrite concentrations in the control ponds that were relatively higher than treatment A and B.

Leopard coral grouper, Plectropomus leopardus is one of the most economically important finfish fish in Indonesia and the demand for the grouper is rapidly increasing in Asia and the Pacific. Grouper exports from Bali were 1,613 mt in 2001, 2,082 mt in 2002 and 2,861 mt in 2003. Understanding the reproductive biology of fishes is an important component in developing mariculture and in the management of capture fisheries. This study reports on the reproductive biology of 86 coral groupers collected from various locations in Indonesia. The length and weight of these fish were recorded and related to gonad development. There was a strong relationship between length and weight; weight being proportional to the length raised to the power (b value) 3.2. As the value of b was greater than 3, this suggests that growth is allometric. Histological analysis 73% of the fish were immature, 19% were in transition from females to males, only 4% were male, and only 2 fish (2%) had mature gonads: these were female. The sex of 2 fish could not be determined. From these data it can be seen that the leopard coralgrouper has asynchronous gonad development. The two fish that were mature contained 343,980 and 429,259 oocytes and three distinct sizes of oocytes could be found. This suggests that the grouper is a multiple spawner. If fish are required for brood stock, this study has shown that only those with a length greater than 35 cm in standard length should be taken from the wild.

To assess the suitability of bioremediated sewage effluent from Shehzad Town, Islamabad for fish cultivation, it was tested for the presence of microflora pathogenic to fish and also for its water quality, at National Agriculture Research Centre (NARC), Islamabad. There was no significant difference found in the microflora of fresh and bioremediated sewage effluent and no evidence of disease causing species was observed during the study. A total of 15 fungal isolates and 7 bacterial isolates were obtained from bioremediated sewage effluent. Identified isolated microflora was found to be non-pathogenic to fish. Most prominent fungal species were that of Aspergillus, Alternaria, and Penicillium, whereas Pseudomonas, Proteus, and Elizabeth were prominent bacterial species in both fresh and bioremediated sewage effluent.

Pathogen identification based on biochemical properties can barely differentiate Streptococcus iniae and S. agalactiae. Beside that, this technique is also limited by the length of time required to complete the assays. Therefore, rapid diagnosis is necessary to initiate prompt therapeutic and prophylactic measures in order to limit any potential economic losses caused by such pathogens. The aim of the present study was to identify Streptococcosis species using amplification of S. agalactiae DNA sequence with species-specific primer Sdi 61 AGGAAACCTGCCATTTGCG and Sdi 252 CAATCTATTTCTAGATCGTGG and perform phylogenetic analysis based on DNA nucleotide sequence data. The sequencing of PCR products was performed at BPPT Puspiptek Serpong by using the respective PCR primers, Big Dye Terminator Chemistry and AmpliTaq-FS DNA polymerase. The sequencing reactions were run on the ABI Prism version 3103 – Avant Genetic Analyzer (USA) and the result was read by Sequence Navigator program (Applied Biosystem). Alignment multiple analysis was done based on the data from Genebank with BLASTN (http://blast.ncbi.nlm.nih.gov/blast.cgi) on the nucleotide level. Neighbor-joining phylogenetic trees were generated with Genetyx programme version 7 with UPGMA and MEGA software version 4.0. The result revealed that the isolates from brain, eye, and kidney of diseased Tilapia were infected by S. agalactiae and it has 99% similarity with Genebank. It has close relationship with S. agalactiae at genebank with UPGMA method. These isolates showed high variation in the first sequence which is similar to S. iniae. The information of S. agalactiae genomes suggests that gene acquisition, duplication, and reassortment have played an important role in genetic diversity and evolution of S. agalactiae. Screening of breeder fish stocks with the developed PCR methodology, followed by elimination of infected stocks, would provide an efficient strategy to control fish infected by streptococcosis.

Barb (Barbonymus balleroides) considerably has economic potential as aquaculture commodity. However, there was still lack of development on aquaculture for this species. This study was conducted to observe the effect of different stocking density on growth of barb. The fish (body weight: 14.89 ± 0.13 g) were stocked in nine floating nets (dimension: 2 m x 2 m x 1 m) inside the concrete ponds with three stocking density treatments (10, 15, and 20 fish/m3). Each treatment consisted of three replications. Fish were fed on commercial pellet (30% of crude protein) as much as 3% of the biomass per day with twice a day of feeding frequency. Data of growth performances (body weight, specific growth rate, average daily growth, biomass, food conversion ratio, and survival rate) were collected every 30 days during 90 days of rearing period. Water quality variables (temperature, pH, and dissolved oxygen) were observed during experiment. The results showed that the optimal stocking density for the growth of barb was 10 fish/m3. Best value of food conversion ratio was found 10 fish/m3 compared with 15 and 20 fish/m3 (P<0.05). Meanwhile, there were no significant differences on survival rate between treatments. These results also showed the potential of rearing barb on culture ponds with appropriate stocking density.

Batur Lake located in Bangli District is one of fisheries-basedregions in Bali with niletilapia as the main cultured species. Monitoring on environmental conditions of the lake was carried out to get the vertical and horizontal water quality profiles of the lake. Climatology condition of the area was also presented in the study. The study area were between 8o13’-8o18’ S and 115o22’-115o26’ E. Field survey was done with random and transect sampling points distribution. The water quality monitored in the lake essential ly covers important parameters such as depth, transparency, temperature, pH, dissolved oxygen, salinity, nutrients (ammonia, nitrate, nitrite, and phosphate), sulfide, chlorophyll, and planktonic composition. Results of spatial analysis (vertically and horizontal ly) of water quality indicated that oxygen concentration up to 10 m deep is still appropriate for nile tilapia culture. Nutrient (phosphate, ammonia, nitrate, and nitrite) contents of the lake meet the standard levels set by Ministry of Environment of Indonesia, and were still suitable for aquaculture operation at depth 710 m. From climatology point of view, it is known that the extreme climate occurred in June-August resulting in water mass changes, thus, affecting aquaculture sustainability in the lake.

Recently, bacteria as probiotic usage in aquaculture are deeply investigated. Probiotic application in aquaculture leads to alteration in bacteria community within environment and inside digestive system of the host. However, the evidence of treated bacteria presence is very limit. This study was aimed to reveal the effectiveness of PCR-DGGE method to bring some evidence of the applied probiotic existence within aquatic organism. Two species of Lactobacillus were applied in this experiment. Litopenaeus vannamei was used as host for applied bacteria, L. vannamei was reared using natural sea water in the 45 cm x 15 cm x 25 cm aerated glass tank. Twice daily of enriched Artemia were gived as nutrition during experiment. The result showed that Lactobacillus represent higher in treatment group compare with control after 20 days treatment. In the other hand there was no different of bacteria number between two treated Lactobacillus. PCR-DGGE is a rapid and reliable method for bacteria detection within aquatic organism.

Pearl oyster, Pinctada maxima is one of economical ly important species in aquaculture, particularly in pearl industry. Information on genetic variation of pearl oyster is required in order to be able to make a sound management of it’s natural populations and to utilize it to improve the quality of pearl culture. Five populations from different geographic locations of pearl oyster, Pinctada maxima, (Sumbawa, Bali, Selat Sunda, Belitung, and South Sulawesi) were analyzed for genetic variation within a 750-base pair region of the Mitochondrial Cytochrome Oxidase subunit I (MtCOI) gene using Restriction Fragment Length Polymorphism (RFLP) technique. The analysis of 25 pearl oyster samples, their haplotype diversity ranged from 0.0970 to 0.1939 and the number of haplotype in each population ranged from three to five haplotypes. Clustering of populations based on Nei’s genetic distances and constructed using unweighted pair-group method with Arithmetic mean (UPGMA) showed that the populations were clustered into two groups: Belitung, Selat Sunda, Bali and Sumbawa in one group, while South Sulawesi in the second group.

The metabolic rate of aquatic animals is closely related to oxygen concentration and influenced by internal and external factors. Despite its high value as marine fish species in South Korea, information on rock bream Oplegnathus fasciatus metabolism is scarcely available. This study observed the standard metabolic rate (SMR), routine metabolic rate (RMR), and active metabolic rate (AMR) of rock bream Oplegnathus fasciatus subjected to different temperature settings. Another observation was performed to find out the maximum metabolic rate (MMR) on rock bream subjected to different salinity settings. Fish (TL: 26.86 ± 0.29 cm and BW: 469.40 ± 38.21 g for SMR, RMR, and AMR measurement; TL: 26.7 ± 0.4 cm and BW: 451.0 ± 44.4 g for MMR measurement) were observed using respirometer (dimension = 30 cm × 20 cm × 20 cm; volume: 10.4 L) inside a recirculation systems. SMR, RMR, and AMR were measured at 15°C, 20°C, and 25°C. Meanwhile, MMR was measured at 15, 25, and 35 psu. The results showed that SMR, RMR, and AMR increased linearly by increasing the temperatures (SMR: 58.7 ± 3.2, 102.7 ± 4.3, and 157.1 ± 4.1 mg O2/kg/h at 15°C, 20°C, and 25°C, respectively; RMR: 66.0 ± 8.6, 112.6 ± 10.2, and 175.2 ± 21.3 mg O2/kg/h at 15°C, 20°C, and 25°C, respectively; AMR: 73.4 ± 7.4, 122.0 ± 6.3, and 196.7 ± 15.4 mg O2/kg/h at 15°C, 20°C, and 25°C, respectively), whilst MMR decreased by lowering salinity (48.5 ± 5.2, 61.1 ± 5.5, and 89.3 ± 14.7 mg O2/kg/hour at salinity of 15, 25, and 35 psu, respectively).
