“…The results showed that the feed intake was the same for all treatments, indicating that Bacillus NP5 supplementation in the feed did not affect its palatability (Tantikitti 2014). Similar results were observed in tilapia (Elsabagh et al 2018), juvenile olive flounder (Lee et al 2019), and rainbow trout (Nargesi et al 2019). Supplementation of 1.2-1.4% Bacillus.…”

Abstract. Putra AN, Mustahal, Syamsunarno MB, Hermawan D, Fatimah DG, Putri PB, Sevia, Isnaini R, Herjayanto M. 2021. 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.

“…Artificially cultured fishes are subjected in the hatchery to water quality and other parameters that can compromise the consistent production of healthy juveniles [ 148 ], although probiotic applications among broodstock, embryos and larvae have been studied inadequately. Female rainbow trout brood stock in raceway ponds supplemented with multi-probiotics before spawning season demonstrated production of eggs with higher diameters, increased fecundity, fertilization and hatching, yolk sac absorption, and eye development [ 14 ]. These results are consistent with beneficial responses to multiple-species LAB probiotic applications in the zebrafish hatchery, which led to consistent improvements in every measurable parameter of larval performance [ 149 ].…”

“…[ 13 ] for aquatic organisms as, “a probiotic organism can be regarded as a live, dead or component of a microbial cell, which can be administered via feed or into rearing water, benefiting the host by improving growth performance, feed utilization, immune health status, infectious disease resistance, and stress responses which is achieved at least in part via improving the microbial balance in hosts or ambient environment”. Probiotic research in the last decades has revealed positive effects on growth [ 14 , 15 ], digestive enzymes activities and feed utilization [ 16 ], immunity with upregulation of immune related genes [ 17 , 18 ], improvement of beneficial microbes in the gut and positive modification of intestinal structure [ 19 ], and disease protection [ 20 , 21 ], leading to an eco-friendly aquatic environmental management [ 22 ] in fish and shellfish farming.…”

The Nile tilapia Oreochromis niloticus, Atlantic salmon Salmo salar, rainbow trout Oncorhynchus mykiss, olive flounder Paralichthys olivaceus, common carp Cyprinus carpio, grass carp Ctenopharyngodon idella and rohu carp Labeo rohita are farmed commercially worldwide. Production of these important finfishes is rapidly expanding, and intensive culture practices can lead to stress in fish, often reducing resistance to infectious diseases. Antibiotics and other drugs are routinely used for the treatment of diseases and sometimes applied preventatively to combat microbial pathogens. This strategy is responsible for the emergence and spread of antimicrobial resistance, mass killing of environmental/beneficial bacteria, and residual effects in humans. As an alternative, the administration of probiotics has gained acceptance for disease control in aquaculture. Probiotics have been found to improve growth, feed utilization, immunological status, disease resistance, and to promote transcriptomic profiles and internal microbial balance of host organisms. The present review discusses the effects of single and multi-strain probiotics on growth, immunity, heamato-biochemical parameters, and disease resistance of the above-mentioned finfishes. The application and outcome of probiotics in the field or open pond system, gaps in existing knowledge, and issues worthy of further research are also highlighted.

“…In recent years, researchers have been reporting the relationship between biometric parameters and blood parameters of fishes to distinguish the healthy animals from disease-infected animals, and to evaluate the precise health status of the fish (Fazio et al, 2015;2017). Many authors have reported the influence of haematological parameters of fishes which depends on different types of feed (Dahiya et al, 2012;Nargesi et al, 2020;Ahmadifar et al 2020). However, very few reports are available related to the haematological indices and immune response of fish health (Ahmed et al 2020).…”

The study aims to analyze the haematological parameters of Cyprinus carpio with reference to the formulation of the probiotic fortified feeds using a machine learning approach. C. carpio fed with pelletized feed, probiotic pelletized feed (5% Lysinibacillus macroides), probiotic pearl beads (5% L. macroides) and probiotic rice puff (5% L. macroides) for 60 days. At the end of the experiments, using blood samples, the haematological indices such as leucocytes, erythrocytes, hemoglobin, hematocrit and packed-cell-volume, were analyzed. Duncan's Multiple Range Test showed that the haematological parameters in control feeding regimes significantly (P<0.05) were low compared with that of the probiotic feeding regimes. The data sets of different feeding regimes were classified using the machine learning method. In the present study, the classifiers like the Random Forest, the Linear Model, and the Decision Tree were employed. To identify the relationship between the features, correlation coefficient and dendrogram were applied. The results of the machine learning method showed high accuracy (98%) in random forest methods followed by the decision tree method. The correlation coefficient between the haematological indices recorded a positive value. But, calculated values of mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular haemoglobin concentration were either low positive or negatively correlated with other haematological indices. Based on the results, the Random Forest, Linear Model and Decision Tree Analysis might be considered for haematological classification of the fish haematological data set.
