Abstract

Catfish Clarias sp. is one of the leading commodities in demand and has economic value. Low survival due to cannibalism and disease is a serious problem. To overcome these problems is application of bioflocs and probiotics Bacillus NP5. This study aimed to analyze the appropriate dose of Bacillus NP5 probiotic addition to the biofloc system to improve the health status, growth performance, water quality, and resistance to A. hydrophila. The catfish fry (Clarias sp.) with an average weight of 1.79±0.05 g was used in the experiment for 40 days, reared in tanks with the dimension of 60×30×35 cm3. The experiment applied a completely randomized design (CRD) of five treatments with three replicates, namely KN (negative control), KP (positive control), BFT (biofloc application without probiotic bacteria), BFT4 (biofloc application with Bacillus NP5 104 CFU mL-1), BFT6 (biofloc application with Bacillus NP5 106 CFU mL-1). Treatments tested were challenged with A. hydrophila density 104 CFU mL-1 by immersion, except the negative control. After 40 days of rearing, biofloc and Bacillus NP5 treatments had a significant effect (P < 0.05) on growth performance, immune response, water quality, total bacteria in water and the gut compared to the control treatment (P < 0.05). In addition, total A. hydrophila in liver, kidney and water were lower (P < 0.05) in BFT4 and BFT6 treatments than the control. The conclusion of this study is that the bioflocs supplemented with Bacillus NP5 improved the growth performance, immune response and resistance of catfish to A. hydrophila infection.

Abstract

Vibrio parahaemolyticus strain that produces PirA and PirB toxins is the main causative agent of Acute Hepatopancreatic Necrosis Disease (AHPND) in vannamei shrimp. This study aimed to evaluate the effect of biofloc application, probiotic Pseudoalteromonas piscicida 1Ub, and their combination on growth, immune response and resistance of vannamei shrimp infected with V. parahaemolyticus strain. This study used a completely randomized design consisting of biofloc-based system treatment with or without probiotic 1Ub and normal seawater as control. All treatment groups were challenged with V. parahaemolyticus AHPND strain at a cell density of 105 CFU mL”1 through immersion, while the negative control was reared without being pathogenic challenged. The shrimp used were in averaged body weight of 1.3 ± 0.002 g, reared for 21 days and fed five times a day at 06:00, 10:00, 14:00, 18:00, and 22:00 WIB. The results showed that the B+Pro combination challenge test treatment resulted the best growth performance (specific growth rate, absolute length gain and feed conversion ratio) (P<0.05) compared to other challenge test treatments. hrimp treated with B+Pro also showed a lower intestinal cell population of V. parahaemolyticus RfR, and significantly higher immune response values (P<0.05) than those of other challenge test treatments and K+. Furthermore, those parameters supported positive impact on final shrimp survival rates in the experiment. This study shows that the application of combination of biofloc and 1Ub probiotic bacteria can significantly protect and increase the resistance of vannamei shrimp to V. parahaemolyticus AHPND infection.
