Dietary Bacillus NP5 supplement impacts on growth, nutrient digestibility, immune response, and resistance to Aeromonas hydrophila infection of African Catfish, Clarias gariepinus. Biodiversitas 22: 253-261. This study aims to investigate the effects of Bacillus NP5 supplementation as a probiotic on growth, immune response, and resistance of African catfish to Aeromonas hydrophila infection. Catfish with an initial weight of 6.8 ± 0.1 g were fed with different doses of Bacillus NP5 (0%, 1.1%, 1.2% B, 1.3%, and 1.4%) with three replications and reared for 60 days. The first 45 days were used to observed growth performance, and the last 15 days were used to perform challenge tests against A. hydrophila infection. The results showed that the treatment of 1.2% Bacillus NP5 results in the highest specific growth rate (2.55±0.28 day-1) and increased protein and lipid digestibility significantly (P<0.05). Treatment of 1.1-1.3% Bacillus NP5 increase amylase and lipase activity that significantly higher than 0% Bacillus NP5 treatment. Supplementation of Bacillus NP5 significantly increased the leukocyte, phagocytic index, and survival rate in African catfish after A. hydrophila infection. Therefore, the supplementation of 1.2% Bacillus NP5 in the feed increased the growth, immune response, and African catfish resistance to the infection.

Abstract. Putra AN, Syamsunarno MB, Ningrum W, Jumyanah, Mustahal. 2020. Effect of the administration of probiotic Bacillus NP5 in the rearing media on water quality, growth, and disease resistance of African catfish (Clarias gariepinus). Biodiversitas 21: 2566-2575. The purpose of this study was to investigate the effect of administration of the probiotic Bacillus NP5 in rearing media on water quality, growth, and disease resistance of African catfish. The study consisted of three different concentrations of probiotic Bacillus NP5 - C: control, A: probiotic Bacillus NP5 of 1 x 109 CFU/mL, and B: probiotic Bacillus NP5 of 1 x 1010 CFU/mL, on the rearing media of African catfish for 45 days. Based on the results, the lowest significant ammonia (P <0.05) was found in treatment A (1.91 ± 0.17 mg/L), then followed by B (2.12 ± 0.14 mg/L) while the highest was in the control (2.36 ± 0.19 mg/L). Treatment A also had a better immune response compared to other treatments shown with the highest significant number of leukocytes at 6.69 ± 0.17 x 104 cells/mm3 and phagocyte activity at 65.19 ± 0.04%. Furthermore, treatment A significantly resulted in the best specific growth rate and feed conversion ratio (2.02 ± 0.07%.day-1, 1.05 ± 0.07, respectively). The administration of probiotic Bacillus NP5 of 1 x 109 CFU/mL in rearing media significantly improved the ammonia value, growth, and resistance of African catfish to Aeromonas hydrophila infection.

Probiotics have been widely known to have the ability to improve the immune system of livestock and aquatic animal. The present study was carried out to evaluate the effect of dietary supplementation of two probiotic isolates of Enterococcus faecium on hematological parameters of juvenile African catfish, Clarias gariepinus during pre- and post-challenge with aquatic pathogen, Aeromonas hydrophila. The probiotics were previously isolated from vegetable wastes (mung bean sprouts, Vigna radiate and cucumber, Cucumis sativus) which have been fermented for 7 days. The experimental fish (270 tails) with an average weight of 5.13 ± 1.03 g were distributed and divided randomly  into  i) control (30 tails), fed with commercial diet ii) E1 (30 tails), fed with  diets  supplemented  with  108 CFU/ml  of  E. faecium isolated from fermented cucumber, iii) E2 (30 tails), fed with 108 CFU/ml  of  E. faecium isolated from fermented mung bean sprouts. The feeding trial was conducted for 50 days. All experimental groups were then challenged with A. hydrophila (1.5 × 106 CFU/mL) via intraperitoneal injection on day 51. Prior to challenge, blood samples were collected from five fish randomly selected from each group on the day 51 (pre-challenge).  After 72 hours of post-challenge, blood samples were again collected from five fish from each groups. The hematological parameters such as total erythrocyte count  (RBC),  total  leucocyte  count  (WBC),  packed cell volume (PCV),  hemoglobin  (Hb), the derived blood indices of mean corpuscular volume (MCV) and corpuscular hemoglobin concentration (MCHC) were examined.  Hematological profiles of pre- and post-challenge infected juvenile catfish were compared with the control groups. The RBC, Hb, WBC, PCV, MCV and MCHC of fish fed with probiotics showed higher significant difference (P<0.05) as compared to control groups during pre- and post-challenge of pathogen. The high level of RBC and WBC during pre- and post-challenge showed the capability of the probiotics to improve the immune response of juvenile African catfish and thus increased the fish disease resistance against A. hydrophila infection. The result suggested that E. faecium could be used effectively as a probiotic in aquaculture.

The aimed of this research was to evaluate the effects of dietary probiotic microcapsules B.cereus P22 and S. lentus (L1k) at different dose and frequency on growth performance, immune response and resistance of African catfish infected with A. Hydrophila. Probiotics used in this study were B. cereus P22 and S. lentus L1k encapsulated by spray draying method. The research was carried out for 56 days with eight treatments and four replications. The treatments were K- (negative control), K+ (positive control), A (feed supplemented with 0,5% of microencapsulated probiotic, fedevery day), B (feed supplemented with 0,5% of microencapsulated probiotic, fed once every three days), C (feed supplemented with 1% of microencapsulated probiotic, fed every day), D (feed supplemented with 1% of microencap-sulated probiotic with an administration once every three days), E (feed with 2% of microencapsulated probiotic with an administration every day) and F (feed with 2% of microencapsulated probiotic with an administration once every three days). On day 42, all of the fish except K- were challenged by intramuscular injection of A. hydrophila (108 CFU ml-1). In 40 days after infection, there were no significant difference on survival rate (SR) between treatments (p> 0.05). Treatment E displayed the higher growth rate (4,54±0,02%), total probiotic B. cereus (P22) and S . lentus (L1k) (4.06± 0.09 log CFU g-1; 4.02±0.08 log CFU g-1) than other treatments; whereas treatment D showed the best feed conversion rasio(1.191±0.013), and treatment F offered the highest total bacterial count (7.11±0.53 log CFU g-1). An administration of 2% microencapsulated probiotic in every day frequency demonstrated the better growth performance, immune res-ponse and resistance of African catfish to A. hydrophila compare with other treatments. AbstrakPenelitian ini bertujuan untuk mengkaji dosis dan frekuensi pemberian mikrokapsul probiotik melalui pakan terhadap kinerja pertumbuhan, respons imun, dan resistensi ikan lele yang diinfeksi Aeromonas hydrophila.

The histometry, organosomatic parameters and growth performance of African catfish, Clarias gariepinus fed with commercial probiotics, Lactobacillus pentosus supplemented diet was assessed in the present study. Six experimental diets were formulated, at different inclusion levels of Lactobacillus pentosus of 0, 102,104, 106, 108and 1010 cfu in T1, T2, T3, T4, T5 and T6 respectively. C. gariepinus were stocked into concrete tanks of 1.93 m by 1.93 m by 1.09 m. Each experimental diet was fed to three replicate groups of fish for 42 days. At the end of the feeding, histometrical parameters like mucosal fold length, mucosal fold breadth, mucosal fold area improved with increasing supplementation levels of L. pentosus. There was also significantly better P > 0.05 organosomatic parameters in all treatments with increasing level of supplementation. The best growth performance in term of specific growth rate (SGR) and feed conversion ratio (FCR) was observed in Treatment 3 as 10.49±0.23 and 1.56±0.22 respectively. The enhanced growth performance and histometry in fish fed diets with L. pentosus supplementation resulted in the best biological performance in African catfish at 1.0 g per 100 g of feed representing 104 cfu supplementation level. Therefore the present study shows that L. pentosus can be recommended as an important probiotic in aquaculture.

Two experiments were simultaneously conducted withMorus alba(white mulberry) foliage extract (MFE) as a growth promoter and treatment ofAeromonas hydrophilainfection in separate 60 and 30 days trail (Experiments 1 and 2, resp.) in African catfish (Clarias gariepinus). In Experiment 1, four diets, control and control supplemented with 2, 5, or 7 g MFE/kg dry matter (DM) of diet, were used. In Experiment 2, fish were intraperitoneally infected withAeromonas hydrophilaand fed the same diets as experiment 1 plus additional two diets with or without antibiotic. Results of experiment 1 showed that growth was unaffected by dietary levels of MFE. Treatments with the inclusion of MFE at the levels of 5 and 7 g/Kg DM had no mortality. Red blood cells (RBC), albumin, and total protein were all higher for the treatments fed MFE (5 and 7 g/Kg DM). Results of experiment 2 showed RBC, hemoglobin, hematocrit, globulin, albumin, and total protein improved with the increase in MFE in the infected fish. The dietary MFE at the level of 7 g/kg DM reduced mortality rate. In conclusion, MFE at the level of 7 g/kg DM could be a valuable dietary supplement to cure the infected fish.
