Abstract

The Gracilaria genus is a potential source of natural and environmentally-friendly alternatives in improving the survival and growth of shrimp. This study aims to identification immunostimulant molecules extract G. verrucosa and evaluate the utilization of G verrucosa extract as an immunostimulant in improving survival and growth of L. vannamei. Seaweed extraction used ethyl acetate then formulated in the diets. The immunostimulant molecule in the G. verrucosa was analysis. The shrimp were fed a test diet containing extract G. verrucosa at a dose of 2 g kg-1 or extract G. verrucosa-free control diets for 42 days. Shrimps were fed diets containing extract with a specific duration. The observation on the survival and growth of L. vannamei was performed after maintenance at the Laboratory for six weeks. Following, diets containing extract was tested in the field (pond shrimp farm) at the same dose of extract for 58 days. Shrimp was feed diets containing extract once a week, once in the early culture, and diet control, then the survival and growth shrimp were analysis. Concentrations of sulfates and carbohydrates in G. verrucosa ethyl acetate-extract were 24.21% and 13.41%, and crude protein 3.64%. GC-MS pyrolysis results show that G. verrucosa polysaccharide is similar to immunostimulant molecules. The survival shrimp gave diets containing G. verrucosa extract formulation was higher than that of shrimps fed controls diet. The Shrimp fed diets extracts have higher growth than shrimp given control dietsKeywords: Gracilaria, extract, polysaccharides, immunostimulant

Abstract

Management of healthy seaweed aquaculture and control of ice ice disease are important component in seaweed production. To support the integrated prevention of ice ice disease, information about genetic variation of bacterial pathogen and the availability of fast and accurate detection are required. This study aimed to identify bacterial pathogen based on gene sequence analysis 16S-rRNA, construction of specific PCR primer from gene sequent analysis 16S-rRNA from bacteria that had the highest pathogenicity. Gene 16S rRNA of bacteria that had the highest pathogenicity was amplificated with universal primer PCR domain forward primer 63f (5’-CAG GCC TAA CAC ATG CAA GTC-3’) and reverse primer 1387r (5’-GGG CGG WGT GTA CAA GGC-3’). DNA Sequence obtained was compared to data base European Bioinformatics Institute (EBI) BLASTN. Construction and feasibility analysis of primer pair was done using primer 3 program. Two specific primer PCR were successfully constructed namely aSEFM-F (5- CAGCCACACTGGAACTGAGA-3) and aSEFM-R(5 TTAGCCGGTGCTTCTTCTGT -3). Both primer reacted optimum at 60°C and produced 201 bp amplicon. Keywords: pathogenicity, gene 16S-rRNA, PCR, primer, specific

Abstract

This research aimed to know the toxicity of extracellular products (ECP) of Streptococcus agalactiae was tastedin cultured Nile tilapia (Oreochromis niloticus). Streptococcus agalactiae had two haemolytic types: β-haemolyticand non-haemolytic type. Toxicity test of ECP to know the virulancy factor of S. agalactiae was still limited. It wasfound that after tested on 15 fish weighing 15 g through intraperitoneal injection 0,1 ml/fish, both bacteria causedchanges in swimming pattern, palatability, external and internal anatomy macroscopically and microscopically.Extracellular products of S. agalactiae non-haemolytic type (BHIA and BHI 24 h) and β-haemolytic type (BHI 72 h)caused mortality 12 hours after injection and the mortality continued till day 7 th of culture. Whirling happened 96hours after injection with ECP S. agalactiae β-haemolytic type (BHIA 72 h incubation) whereas injection with ECP(BHI 24 h) on 72 h after injection and continued untill day 7 th. Behavior disease signs caused by S. agalactiaeoccured on eyes. There were opacity, purulens, eye shrink, lateral and bilateral exopthalmia and haemorrhage oninfected-fish. Silver staining of sodium dodecyl sulphate-polyacrylamide gels to S. agalactiae revealed thatpredominant 51.8-69.6 kDa bands were present in BHIA ECP fraction. The 69.6 kDa was absent from the BHI ECP.Total protein on non-haemolytic S. agalactiae ECP are 28.18 ppm on BHIA medium and 13.64 ppm on BHI medium.Whereas β-haemolytic S. agalactiae ECP are 2.73 ppm on BHIA medium and 8.18 ppm on BHI medium. Concentrationof protein in ECP was one of factor that caused non-haemolytic S. agalactiae more virulent than β-haemolytic type.The conclusion from the research that ECP was virulent factor on β-haemolytic and non-haemolytic S. agalactiaein fish which caused changes in behavior disease signs.

Abstract

Deoxyribonucleic acid (DNA) vaccine has recently been developed as an alternative vaccine against virus infection.This study was the first step of DNA vaccine development to protect cyprinids including common carp (Cyprinuscarpio) and fancy koi (Cyprinus carpio) from KHV (koi herpesvirus) infection in Indonesia. One of KHV glycoproteingenes, i.e. glycoprotein (GP) was ligated with Japanese medaka (Oryzias latipes) â-actin promoter to generatepAct/GP as a DNA vaccine. Fourty fish in body weight of 10-15 g/fish were individually injected by pAct/GP intomuscle in different dosage of 2.5 μg, 7.5 μg and 12.5 μg/100 μl phosphate buffer saline. Total RNA was extractedfrom the 12.5 μg of pAct/GP-injected fish muscle at 24, 48 and 67 hours post-injection to analyze GP expression byRT-PCR method. Potential of pAct/GP as DNA vaccine was examined by injecting KHV into the 30-days-vaccinatedfish. Both of possitive and negative control fish group were not vaccinated. Possitive control fish group wereinjected with KHV, but negative control fish group were not. KHV-challenged fish were reared for 1 month, and thedeath fish were calculated daily. Result of RT-PCR analysis showed that GP gene expression were detected at 3 dpost-injection. Expression of GP in the vaccinated fish groups helped to improve their survival rate after challengedby KHV. All of fish without DNA vaccination had dead 17 days after KHV injection. The results demonstrated thatpAct/GP had high potency to be used as a DNA vaccine against KHV infection in cyprinids.

Abstract

Application of bioflocs technology and probiotics has improved water quality and production of Pacific white shrimp (Litopenaeus vannamei) culture. This experiment was to verify the effect of probiotic bacteria addition and different carbon:nitrogen (C:N) ratio on water quality and performance of Pacific white shrimp nursery culture. Nursery culture was carried out for 25 days in an aquarium under laboratory condition with stock density of one Post-Larvae (PL) (poslarval) per liter (24 PL/aquarium) of PL16 shrimp. Different C:N ratio resulted a significant difference on shrimp production performance. Treatment of 10 C:N ratio demonstrated the best shrimp growth (20.37 + 0.48% per day in weight and 6.05 + 0.41% per day in length), harvesting yield (1180 + 62 g/m3) and feed efficiency (121 + 6%). There was however no significant difference observed between treatments in water quality.

Abstract

Bacterial disease attack occurs at the hatchery stage, which is considered to be the most serious threat, and often results in mass mortality of shrimp larvae by vibrosis which is that caused by a luminous bacterium identified as Vibrio harveyi. This research was carried out to obtain local isolates of probiotic bacteria that were able to inhibit the growth of V. harveyi and effectively apply it as a biocontrol of vibriosis in shrimp cultures. The research was carried out as follows: (1) In vitro and in vivo selection of probiotic bacteria candidates, (2) Study of the action mechanism and characterization of the selected pro biotic bacteria, (3) Study on application of the selected probiotic bacteria as a biocontrol agent in shrimp cultures. Results of in vitro and in vivo selection provided the best three isolates, which were 1Ub, SKT-b and Ua. The survival rate of shrimp larvae which were not only inoculated by V. harveyi but also with 1Ub, SKT-b and Ua probiotic bacteria were 88.33, 83.33, and 81.67% respectively; where as the positive control treatment (merely inoculated with V. harveyi) gave a 41.67% survival rate and the negative control (without bacterial addition) was 68.33%. Studies using a rifampicin resistant marker (RfR) demonstrated that the number of V. harveyi MR5339 RfR cells in treatments without probiotic addition were higher than the treatment with the probiotic bacteria, in dead larvae, living larvae, as well as in the culture media. Partial sequencing of the I6S-rRNA gene showed that the I Ub isolate was similar to Pseudoalteromonas piscicida, whereas the SKT -b and Ua isolates were similar to Vibrio alginolyticus. Selected probiotic bacteria could be applied directly to shrimp larva culture media, or orally through enrichment of both natural and artificial food.

Abstract

GP-11 KHV DNA vaccine is a vaccine that can be used to induce immunity against the KHV virus (Koi herpesvirus). Vaccination through feed is an alternative way of administering vaccines. The study aimed to examine the effect of giving KHV GP-11 DNA vaccine through feed with different frequencies to KHV infection. The frequency of vaccine administration is GP-11 vaccination once a week; GP-11(1x), GP-11 vaccination twice a week; GP-11(2x), GP-11 vaccination three times a week; GP-11(3x), GP-25 vaccinations three times a week; GP-25(3x), negative control (without KHV test) and positive control (KHV tested). The fish were kept for 28 days after vaccination and then continued with the KHV challenge test for 28 days. The weight of carp ranges from 13.82±2.37 g maintained with a density of 15 fish/aquarium. The results showed that vaccine treatment was able to induce an immune response as indicated by the number of white blood cells, lysozyme activity and post-vaccination antibody titer showed a significant effect compared to controls. Likewise, after the challenge test, supported by IFNγ and IgM gene expression parameters after the challenge test showed the highest value of vaccine treatment rather than control. The efficacy of vaccine was showed by RPS value (%) in each vaccine treatment obtained GP-11(1x) value of 44.7±3.7a, GP-11(2x) of 78.9±18.2b, GP-11(3x) 85.6±12.6b and GP-25(3x) 79.5±18.1b. It was concluded that administering the GP-11 vaccine frequency 2 times a week provides protection as strong as giving a vaccine frequency 3 times a week.Keywords: common carp, DNA vaccine, frequency of administration, koi herpesvirus

Abstract

The purposes of this study were to determine oceanographic and water quality parameters and their suitability for white shrimp Litopenaeus vannamei culture. The measurements were carried out on dry season in Semak Daun Island, Karya Island, and Panggang Island waters of Thousand Islands, with areas of 315.0, 12.0, and 102.8 ha, water depth average of 4.6 m (0.5-28.1 m), 14.6 m (0.5-26.7 m), and 5.3 m (0.8-13.6 m), mean current water velocity of  12.9, 12.7, and 13.5 cm/second, respectively.  In the study areas, we found a diurnal tidal pattern with high wave in January and July-August.  Based on temperature, salinity, and water density in Semak Daun Island waters, there seemingly occurred a turn over indicating a good water circulation, while in Panggang Island and Karya Island waters tended to have a stratification. Generaly, water qualities in the study areas were in the op-timum range for white shrimp culture, i.e., temperature of 29.6-30.8oC, turbidity of 0.10-1.05 NTU, transparency of 5.8-9.7 m, total suspended solid of <8 mg/L, total dissolved solid of 20-164 mg/L, pH of 6.89-7.22, salinity of 32.2-32.3, dissolved oxygen of 5.8-10.8 mg/L, ammonia of 0.068-0.145 mg/L, nitrate 1.247-2.589 mg/L, and phosphate  of 1.021-2.352 mg/L. Moreover, in Semak Daun Island wa-ters, we found the highest suitability for white shrimp culture due to its better water circulation.Keywords: mariculture, coral reef waters, strait, water current, turnover, stratification.
