Nursery Culture Performance of Litopenaeus vannamei with Probiotics Addition and Different C/N Ratio Under Laboratory Condition . WIDANARNI; DEBY YUNIASARI; . SUKENDA; JULIE EKASARI

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.

Evaluation of Biofloc Technology Application on Water Quality and Production Performance of Red Tilapia Oreochromis sp. Cultured at Different Stocking Densities . WIDANARNI; JULIE EKASARI; SITI MARYAM

This study evaluated the effect of biofloc technology (BFT) application on water quality and production performance of red tilapia Oreochromis sp. at different stocking densities. Three different fish densities were applied, i.e. 25, 50, and 100 fish/m3, and for each density there were Control (without external carbon input) and BFT treatments. Mixed sex red tilapia with an initial average body weight 77.89 + 3.71 g was cultured in 3 m3 concrete tanks for 14 weeks. Molasses was added on BFT treatments as the organic carbon source at a C/N ratio of 15. Control treatments of each density tested showed more fluctuated water quality parameters throughout the experimental period. The highest TAN and nitrite-nitrogen were observed in control treatment at a stocking density of 100 fish/m3 (3.97 mg TAN/L and 9.29 mg NO2-N/L, respectively). The highest total yield was observed in control treatment at the highest density treatment (43.50 kg), whereas the highest survival was obtained by BFT treatment at a density of 25 fish/m3 (97.78 + 0.77%). Total feed used in BFT was lower than that of control treatments in particular at 50 fish/m3 density (P < 0.05) suggesting that biofloc could be continuously harvested by the fish as other source of food.

The Use of Synbiotics to Prevent IMNV and Vibrio harveyi Co-Infection in Litopenaeus vannamei ADNI OKTAVIANA; . WIDANARNI; MUNTI YUHANA

This study evaluated the effects on viral immune responses and bacterial co-infection, of different feeding frequencies of a synbiotic supplemented diet given to Pacific white shrimp (L. vannamei). A synbiotic-supplemented diet was formulated from probiotic Vibrio alginolitycus SKT-bR and prebiotics from sweet potato (Ipomoea batatas L.) oligosaccharide. Pacific white shrimp were fed the synbiotic diet at different frequencies, i.e. daily (P1), twice a week (P2), and once a week (P3) for a 30 day pre-challenge test. After the 30 day feeding period, the shrimps were challenged by intramuscular injection of Infectious Myonecrosis Virus (IMNV) and Vibrio harveyi. The results showed that shrimp treated with a synbiotic-supplemented diet showed significantly higher growth performance than control groups (P<0.05). Shrimp treated under regime P1 showed the highest values for phenoloxidase (PO) and respiratory burst (RB) parameters compared to shrimp given the other treatments. Following the challenge test, higher survival rate were seen in the P1 treatment group, in comparison to the positive control, and the P1 treatment group showed the highest values in total haemocyte count (THC), PO, and RB.

Encapsulated Synbiotic Dietary Supplementation at Different Dosages to Prevent Vibriosis in White Shrimp, Litopenaeus vannamei Anis Zubaidah; Munti Yuhana; . Widanarni

The aim of this study was to evaluate the effect of encapsulated synbiotic (Bacillus sp. NP5 and oligosaccharide) dietary at different dosages on growth performance, survival rate, feed conversion ratio, and immune responses of Litopenaeus vannamei against Vibrio infection. The shrimps of the main treatments were fed by the diet that contained three different dosages of encapsulated synbiotic [0.5% (A), 1% (B), and 2% (C) (w/w)] with feeding rate of 5% of shrimp biomass (4 times a day). The shrimps of two control treatments (negative control and positive control) were fed only by commercial feed without supplementation of encapsulated synbiotic. The growth, feed conversion ratio, and survival rate were observed after 30 days of encapsulated synbiotic dietary. The shrimps were then challenged by injection of Vibrio harveyi (6 log colony forming units/mL) 0.1 mL/shrimp, excluded the negative control treatment. Afterward, the survival and immune responses were observed for 9 days after experimental infection. The shrimps treated with 2% encapsulated synbiotic (treatment C) in the diet showed the highest growth performance (2.98 ± 0.42%), feed conversion ratio (1.26 ± 0.19), and better immune responses i.e. total hemocyte counts, differential hemocyte count, phenoloxidase, and intestine bacteria observation compared to those of positive control treatment.

Effect of Probiotic Bacillus megaterium PTB 1.4 on the Population of Intestinal Microflora, Digestive Enzyme Activity and the Growth of Catfish (Clarias sp.) Wahyu Afrilasari; . Widanarni; Anja Meryandini

This study aimed to analyze the effect of Bacillus megaterium PTB 1.4 on the population of intestinal microflora, digestive enzyme activity, and the growth of catfish. Gnotobiotic and normal fish were used. Treatment using gnotobiotic was divided into gnoto (with feed and 100 μg/mL rifampicin) and gnotoplus (with feed, 100 μg/mL rifampicin, and 1% probiotic); whereas treatment using normal fish was divided into normalplus (with feed and 1% probiotic) and normal (only feed). The amount of bacteria on gastrointestinal tract was measured 30 days after treatments using the total plate count method. The results indicated no significant difference in bacterial growth between gnotobiotic and normal fish. The total amount of probiotic bacteria with normalplus treatment was significantly different with gnotoplus. The activity of protease and amylase enzymes, and specific growth rate in normalplus treatment were significantly higher (p < 0.05) than other treatments. Bacillus megaterium PTB 1.4 increased the activity of digestive enzymes and the growth of catfish.
