“…Similarly to previous findings (Standen et al, 2016), we have not noticed influence on FCR. Several management aspects may explain the lack of effects on FCR, such as lower water temperature and dietary protein level, the feeding frequency and the incorporation method of the probiotic.…”

Current results points to the hypothesis that possibly the dosage for best growth performance is not the same as the best dosage for the prevention of infection breaks.…”

“…The improvement of growth performance after probiotic feeding has been observed previously in tilapias receiving several probiont species (Lara-Flores et al, 2003;Pirarat et al, 2011;Standen et al, 2016). The current study is in Figure 2 Liver oxidative stress parameters of Nile tilapia along the growth trial: lipid peroxidation (LPO), catalase, glutathione peroxidase (GPx) and glutathione reductase (GR) activities; glutathione (GSH) and the ratio between reduced and oxidized glutathione levels (GSH/GSSG).…”

“…Lara-Flores et al (2003) observed an influence of probiotics on carcass composition in fingerlings. However, as the fish grow, the effect on body composition seems to attenuate (Telli et al, 2014;Ramos et al, 2015;Standen et al, 2016) as in the current study.…”

“…The microbiota influences the mucosal and systemic immune system of fish (Lazado and Caipang, 2014). Recent study with the commercial probiotic used in the current study reported changes in intestine microbiota in tilapia, as well as up-regulation of intestine genes involved in immune responses (Standen et al, 2016). In the current study, the alternative complement pathway, a non-specific mechanism of protection against putative pathogens as bacteria, fungi, viruses or parasites (Merrifield and Ringø, 2014), was significantly higher in fish-fed diets supplemented with 2.3 × 10 6 CFU/g diet (A 2 , 6 g/kg) but the not with the lower dosage (A 1 , 3 g/kg, 1 × 10 6 CFU/g).…”

Probiotic administration can be a nutritional strategy to improve the immune response and growth performance of fish. The current study aimed to evaluate the effects of a probiotic blend (Bacillus sp., Pediococcus sp., Enterococcus sp., Lactobacillus sp.) as a dietary supplement on growth performance, feed utilization, innate immune and oxidative stress responses and intestinal morphology in juvenile Nile tilapia (Oreochromis niloticus). The probiotic was incorporated into a basal diet at three concentrations: 0 g/kg (A 0 : control), 3 g/kg (A 1 : 1.0 × 10 6 colony forming unit (CFU)/g) and 6 g/kg (A 2 : 2.3 × 10 6 CFU/g diet). After 8 weeks of probiotic feeding, weight and specific growth rate where significantly higher in fish-fed A 1 diet than in fish-fed A 0 . Alternative complement in plasma was significantly enhanced in fish-fed A 2 when compared with A 0 . The hepatic antioxidant indicators were not affected by probiotic supplementation. Villi height and goblet cell counts increased significantly in the intestine of fish-fed A 1 and A 2 diets compared with A 0 . The dietary probiotic supplementation was maintained until 20 weeks of feeding. Then the selected immune parameters, digestive enzymes and apparent digestibility of diets were studied. No effect of probiotic feeding was observed after that longer period supplementation. The dietary supplementation of mixed species probiotic may constitute a valuable nutritional approach towards a sustainable tilapia aquaculture. The improvement of the immune responses and intestinal morphology play an important role in increasing growth performance, nutrient absorption and disease resistance in fish, important outcomes in such a competitive and developing aquaculture sector.

Traditional Chinese Medicine Enhances Growth, Immune Response, and Resistance to Streptococcus agalactiae in Nile Tilapia

et al. 2019

Herbal supplements are suitable for improving fish health and combating diseases in fish culture. However, the mechanism of action of many herbal mixtures remains unclear. This study was conducted to evaluate the effects of traditional Chinese medicine (TCM; a mix of Astragalus membranaceus, Angelica sinensis, and Crataegus hupehensis at a ratio of 1:1:1 on a weight basis) on growth, immune response, and disease resistance in Nile tilapia Oreochromis niloticus. Experimental fish (mean ± SE weight = 57 ± 1 g) were divided into two groups: a control group and a TCM (10 g/kg) group. After 4 weeks of the experimental trial, a significant increase in weight gain and specific growth rate and a lower feed conversion ratio were observed in fish fed a TCM-supplemented diet compared with control fish. Similarly, the immune response of Nile Tilapia in the TCM group showed enhanced lysozyme, superoxide dismutase, catalase, and immunoglobulin levels compared with the control fish. In comparison with the control, fish fed TCM showed significant up-regulation of β-defensin, lysozyme, heat shock protein 70, superoxide dismutase, and catalase genes in the intestine and head-kidney tissues. After a Streptococcus agalactiae challenge, survival of Nile Tilapia in the TCM group was 70% compared with 35% in the control. These results indicate that the TCM mixture in this study can elevate the immune response and disease resistance of Nile Tilapia.

Dietary Incorporation of Bacillus subtilis and Bacillus licheniformis Mixture (DiPro Aqua) Ameliorates Growth Performance, Immune Response, and Intestinal Morphology in Rainbow Trout

The current study was designed to investigate the role of a commercial probiotic containing equal proportions (1:1) of Bacillus subtilis and B. licheniformis spores (1.6 × 10 12 CFU/kg; DiPro Aqua) on the growth, immune response, and intestinal morphology of Rainbow Trout Oncorhynchus mykiss. A total of 168 Rainbow Trout fry were randomly divided into four groups and were fed diets with different doses of DiPro Aqua (control: 0 CFU/kg; treatment 1 [T1]: 8 × 10 8 CFU/kg; T2: 16 × 10 8 CFU/kg; T3: 24 × 10 8 CFU/kg) for 56 d. The highest body weight gain and specific growth rate were obtained in the T2 and T3 groups. In addition, the highest feed conversion ratio was measured in the control group. The results showed that the serum total immunoglobulins and total protein content were increased in fish that were fed the T2 and T3 diets compared to those that received the T1 and control diets (P < 0.05). The highest alternative complement pathway hemolytic activity was measured in T2 fish compared to the other groups. According to the antibacterial activity of the skin mucus samples against Yersinia ruckeri, dietary levels of DiPro Aqua improved the mucus bactericidal activity and the maximum effect was recorded in the T2 group. The dietary levels of the probiotic mixture, especially in T2, increased the villus length, villus width, and crypt depth within the distal intestine compared to those in the control group. In conclusion, the optimal dietary dose of DiPro Aqua to boost growth performance, immunity, and intestinal morphology in Rainbow Trout was 2.0 × 10 8 CFU/kg based on polynomial regression analysis.In today's world, aquaculture plays the most crucial role in providing seafood for humans due to the growing population and the depletion of wild fishery stocks. Intensive and super-intensive aquaculture operations are developed to produce more fish and shellfish, while the most important issues faced in these production systems are poor water quality, infectious disease outbreak, and exposure to various stressors that can negatively affect the growth performance and survival rate of cultured aquatic animals (Banerjee and Ray 2017;Rico et al. 2017). In this context, fish farmers commonly use a wide range of antibiotics and chemotherapeutics for controlling and treating infectious diseases (Dawood et al. 2018;Abdel-Latif et al. 2020). In some cases, antibiotics are no longer effective in treating pathogens due to antibiotic-resistant germs (Han et al. 2015;Dawood et al. 2020). Among several alternative strategies, the use of natural feed additives such as probiotics, prebiotics, and symbiotics to improve the growth performance and immune system of fish has recently increased to make the aquaculture industry profitable and sustainable (
