“…Many previous studies have demonstrated similar effects in aquatic animals (Staykov et al, 2007;Torrecillas et al, 2007;Burr et al, 2008;Taati et al, 2011;Amirkolaie et al, 2013). Colonization by beneficial bacteria that were induced by the consumption of dietary Immunogen ® may account for these positive impacts.…”

We studied the effects of the proprietary prebiotic Immunogen ® on the growth, hematology and gut microbiota of common carp fingerlings. A basal diet was formulated using common feed ingredients and supplemented with Immunogen ® at concentrations of 0, 5, 10, 20 and 40 g kg -1 , each of which was tested experimentally on replicated groups of fish. The trials ran for 8 weeks. Common carp fingerlings with an initial weight of 4.82 ± 0.05 g were randomly distributed among the experimental tanks at a stocking density of 25 fish per tank. The experimental diets were provided thrice per day; on each occasion the fingerlings were given a weight of feed that amounted to 4% of fish biomass. At the end of the experimental period, we determined the growth performance, feed conversion ratio, hematological parameters, body composition and gut micro-flora parameters of the test fish. Inclusion of 5 g kg -1 Immunogen ® in the diet significantly improved growth performance and feed utilization in comparison with controls. However, the whole-body composition of the fish was not significantly influenced by prebiotic inclusion. Inclusion of 5 g kg -1 Immunogen ® significantly increased the total bacterial and Lactobacillus counts in fish intestines, but these bacterial parameters were significantly negatively impacted by higher concentrations of the prebiotic. Red blood cells counts were increased by prebiotic dietary supplementation at concentrations of 5 and 10 g kg -1 prebiotic. Glucose and cholesterol levels were elevated by administration of Immunogen ® . Thus, dietary supplementation with 5 g kg -1 Immunogen ® improved fingerling common carp growth performance and feed utilization, and beneficially influenced the gut microflora.

“…Our results indicate that supplementation with β-G and MOS (0.3% in feed by weight) improved growth performance in and feed utilization by Nile Tilapia. Use of prebiotics containing β-G and MOS was previously found to improve the growth performance of Common Carp Cyprinus carpio, Beluga Huso huso, and sea cucumbers Apostichopus japonicus (Gu et al 2011;Ta'ati et al 2011;Ebrahimi et al 2012). Ye et al (2011) reported that the use of two types of prebiotic (fructooligosaccharides and MOS) in the diets of Olive Flounder Paralichthys olivaceus yielded better growth performance than the use of a single product.…”

We studied the effects of a combination of dietary beta‐glucans (β‐G) and mannan oligosaccharides (MOS) on Nile Tilapia Oreochromis niloticus. Three‐hundred‐sixty fingerlings (mean mass ± SD = 8.7 ± 0.4 g) were separated into three groups (G1, G2, and G3) of 120 fish; G1 (control group) was fed a basal diet, whereas G2 and G3 were fed prebiotic‐supplemented diets at final levels of 1.5 and 3.0 g/kg feed, respectively. Each group was subdivided into two subgroups: subgroup A was fed for 60 d to evaluate growth performance, nutrient utilization, intestinal morphometry, and body composition; and subgroup B was fed for 30 d to evaluate immune status and disease resistance. The best growth and feed utilization were observed in G3. There was no significant difference in final body weight or weight gain between G2 and G1 after 30 d, whereas both variables were significantly higher in G2 than in G1 after 60 d. At the end of the feeding period, G2 had a better feed conversion ratio than G1. Villus height, number of goblet cells, and number of intraepithelial lymphocytes were greatest in G3, followed by G2 and then G1. Whole‐body protein content and fat content were higher in G3 than in G2 and G1. Only G3 had significantly higher serum total protein, albumin, and globulin than G1. Serum killing percentage and phagocytic activity were significantly higher in G3 than in G1 and G2, whereas serum lysozyme activity was significantly higher in G3 and G2 than in G1. The nitric oxide assay indicated a significant effect in G3 compared with G1 after 30 d. Fish that were fed the prebiotic mixture had better relative percent survival than G1 fish after challenge with Yersinia ruckeri. Dietary supplementation with β‐G and MOS in combination improves the performance of Nile Tilapia.

“…Interestingly, in this research the maximum level of RPC inclusion in sturgeon diet was 53 % and at this level the dietary protein was almost completely RPC protein. Even if we decided to not analyze productive results, we interestingly observed that the specific growth rate (SGR) was 5 times better than the case of white sturgeon (A. transmontanus) (Gawlicka et al, 2002), and the productive parameters were also better than Beluga sturgeon (Hosseini et al, 2010;Ta'ati et al, 2011), "AL" hybrid sturgeon , hybrid sturgeon (Acipenser schrenckii x Huso dauricus) (Qiyou X. et al, 2011) and white sturgeon (Lin et al, 1997).…”

The aim of this research is the substitution of fish meal with rice protein concentrate (RPC) in the nutrition of Siberian sturgeon (Acipenser baerii) diet. 240 sturgeons of initial mean body weight of 19.1±6.7 g were used. 3 isonitrogeonous (CP 42.4%) and isoenergetic (19.9 KJg -1 DM) diets were formulated with 20% of RPC inclusion (R20), 35% inclusion (R35), 53% inclusion (R53) against a control diet, fish meal based (FM); feeding ratio was 1.5% of BW. All the diets and fish fillets were analyzed to determine the proximate composition. The diet amino acid composition was measured and fillet colour was detected at the end of experimentation. Fish growth showed very good performances of sturgeon fed with high RPC inclusion, but these data were not considered conclusive because of technical problems during the experimentation. However, considering that the highest level of RPC in the sturgeon diets corresponded to an almost complete substitution of fish meal in the fish diet, the result obtained from fish quality analysis showed no adverse effect of experimental diets, with the only limitation of high muscle lipid storage, in fish fed with highest level of RPC inclusion.
