Background The objective of the present study was to evaluate the growth performance and feed utilization of African catfish fed a commercial diet and Clarias gariepinus reared in the biofloc system enhanced with probiotic. Methods The treatment was the frequency of probiotic application into the cultured system, namely, 5-day interval, 10-day interval, and 15-day interval for 60 days of experiment. Biofloc culture was grown in an experiment tank (vol. 2000 L) by mixing the probiotic (sp.) 10 mL and molasses 200 mL per liter of Bacillus water. The fish was stocked into the biofloc system 7 days after cultured at stocking density of 1000 fish tank. The fish was fed a commercial diet that contains 38% crude protein, twice a day at satiation. The application of probiotic was reperformed after 5 days, 10 days, and 15 days after stocking. Results The study showed that the growth performance, survival, and feed utilization of African catfish were higher in the treatment at 5-day intervals over 60 days. The ANOVA test showed that the application frequency of probiotic into biofloc system of cultured media had the significant effect on the growth performance, survival rate, and feed utilization of African catfish. Conclusion The best growth performance and feed utilization were found at the application of probiotic into biofloc system at 5-day intervals over 60 days.

This experiment was carried out to evaluate the effects of the probiotic, Lactobacillus acidophilus, on the growth performance, haematology parameters and immunoglobulin concentration in African catfish Clarias gariepinus fingerling. Two experimental diets were formulated to contain 35 g kg−1 crude protein and 10 g kg−1 lipids accordingly and fed three times daily for 12 weeks to 25 C. gariepinus fingerlings per fibreglass tank in 12 replicates each. The control diet was prepared with no probiotic supplementation whereas the second diet was prepared supplemented with a probiotic, L. acidophilus, containing about 3.01 × 107 colonies/g of diet. The results show that growth performance [specific growth rate (SGR) and relative growth rate (RGR)], nutrient utilization [protein efficiency ratio (PER) and feed conversion ratio (FCR)] and survival were significantly (P<0.05) higher in fish maintained on the probiotic-supplemented diet compared with those on the control diet. Haematology parameters (packed cell volume, haemoglobin, erythrocyte sedimentation rate, red blood cell and white blood cell, total serum protein, Ca2+, Mg2+, Cl−, glucose and cholesterol) and total immunoglobulin concentrations were also significantly better in fish fed the probiotic-supplemented diet than in the control. Although the water quality parameters monitored were better in the fish fed the probiotic-supplemented diet than in the control, the parameters were not significantly different (P>0.05). From the results of this experiment, we conclude that L. acidophilus can be used as a probiotic agent in African catfish culture, to enhance fish health, survival and better feed efficiency and growth performance.

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 10 9 CFU/mL, and B: probiotic Bacillus NP5 of 1 x 10 10 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 10 4 cells/mm 3 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 10 9 CFU/mL in rearing media significantly improved the ammonia value, growth, and resistance of African catfish to Aeromonas hydrophila infection.

This study aimed to establish the impact of commercial probiotics on European catfish growth parameters and water quality in recirculating aquaculture systems. For the study, the European catfish were placed in two tanks with 45 fish in each tank. Average body weight and length at the beginning of the study were 133.0 g and 27.0 cm, respectively. Rearing conditions and feeding regime were identical, and the only difference was that 1 ml of commercial probiotics was poured into the water of one experimental tank every other day. The experiment lasted for 42 days. Weight and length were measured every 2 weeks. After each measurement, European catfish growth parameters, feed conversion ratios, and feed efficiency were established. After the end of the study, it was established that there were significant differences between specific growth speed, daily growth index, feed conversion ratio, and feed efficiency (P < 0.05) for the fish reared in two experimental groups. Statistically significant differences in the water parameters were established among ammonia, nitrite, and dissolved oxygen concentrations (P < 0.05). Differences in temperature, nitrates, and pH were statistically insignificant. The results of this study showed that commercial probiotics can be used in the European catfish culture to enhance water quality, feed efficiency, and growth performance.

At present, the application of probiotics in aquaculture is gaining wide acceptance for its beneficial effect on fish production. This study focused on evaluating the potency of a commercial multi-strain probiotic on mean growth, feed utilization parameters, yield and survival for profitable cage culture of striped catfish, Pan-gasianodon hypophthalmus at haor floodplain of Bangladesh. The present study was designed using five treatments (n = 3) in which the fishes were fed commercial pellet diets enriched with 0 % (Control-P 0.00), 0.1 % (P 0.10), 0.15 % (P 0.15), 0.2 % (P 0.20) and 0.25 % (P 0.25) probiotic. kg − 1 feed for 12 weeks. End of the culture period, the fish groups fed probiotic supplemented diets exhibited significant improvement in growth parameters. Weight gain, survival rate, relative growth rate, specific growth rate and protein efficiency ratio were significantly (P < 0.05) higher in P 0.20 (808.44 ± 3.67 g, 96.71 ± 0.16 %, 1496.12 ± 2.69 %, 3.08 ± 0.01 % and 3.03 ± 0.01) compared to P 0.00 , P 0.10 and P 0.15. The feed conversion ratio significantly (P < 0.05) decreased in P 0.20 (1.21 ± 0.01) than other treatments. Significantly (P < 0.05) higher production of P. hypophthalmus was attained in P 0.20 (17.20 ± 0.05 kg.m − 3), which ultimately boosted gross revenue. The highest benefit-cost ratio was obtained from P 0.20 (1.54 ± 0.00). The growth and economic parameters did not exhibit any significant difference between P 0.20 and P 0.25. However, minimal probiotic inclusion is preferable for its reduced input cost. The overall results indicated that 0.2 % dietary probiotic supplementation hones the growth, yield and survival for profitable floodplain cage culture.
