“…Similar results were achieved by Ye et al (2011) [41], who studied Japanese flounder (Paralichthys olivaceus) fed a diet supplemented with synbiotics. Higher levels of LZ and total Ig were also observed after diets given to different fish species had been enriched solely with β-glucan [1,21,24,28,34]. The results of Cp activity suggested that β-1,3/1, 6-glucan and L. plantarum had no negative influence on hepatocytes, nor did they implicate the presence of acute phase proteins, which are a heterogeneous group of serum proteins synthesized in the liver [34].…”

Background: The aim of the study has been to compare the effect of dietary supplementation of β-1,3/1,6-glucan, Lactobacillus plantarum bacteria or their mixture on the growth performance, selected parameters of the immune system as well as the liver and intestinal histology of roach. Fish were fed for 14 days with four different diets, each treatment being carried out in triplicate. In control group, fish were fed dry commercial starter feed Aller Performa 2 (Aller Aqua, Denmark). The other experimental fish groups received the same commercial starter feed supplemented with: 1% β-1,3/1,6-glucan (Leiber® BetaS) in group G; 10 8 cfu L. plantarum g − 1 in group L; 1% β-1,3/1,6-glucan + 10 8 cfu L. plantarum g − 1 in group G + L. The stimulating effect of the tested preparations was evaluated once the feeding with commercial feed exclusively was resumed and 2 weeks afterwards. Results: No effect on the survivability and growth performance of the fish was observed in any of the groups. Supplementation of feed with β-1,3/1,6-glucan improved (P < 0.05) selected parameters of innate humoral immunity and the pinocytotic activity of phagocytes. Increased respiratory burst activity of head kidney phagocytes (RBA) was observed in groups L and G + L (P < 0.05), and the effect persisted for 2 weeks after the commercial feed regime was resumed. An analogous tendency was determined for the killing activity of phagocytes (PKA) of the head kidney with respect to Aeromonas hydrophila, although this effect appeared only during the feed supplementation period. Supplying roach with β-1,3/1,6-glucan, singly or with L. plantarum, had no effect (P > 0.05) on the proliferation of mitogen-activated lymphocytes. However, an increase in the number of CD3-positive cells and goblet cells was noticed in the digestive system of the L group fish (P < 0.05).

“…In our review of the literature, we found that the inclusion level of yeast SCP was typically lower than that for other species, although both yeast and yeast extracts were frequently used, with most studies focusing on the Pacific white shrimp (Litopenaeus vannamei). We focused on studies that used yeast as a protein source above 10 g/kg in the diet, although there are several reviews that focus on the use of yeast and fungal polysaccharides (beta-glucans and MOS) as a probiotics and immunostimulant for shrimp [161,162].…”

Single-cell ingredients (SCI) are a relatively broad class of materials that encompasses bacterial, fungal (yeast), microalgal-derived products or the combination of all three microbial groups into microbial bioflocs and aggregates. In this review we focus on those dried and processed single-cell organisms used as potential ingredients for aqua-feeds where the microorganisms are considered non-viable and are used primarily to provide protein, lipids or specific nutritional components. Among the SCI, there is a generalised dichotomy in terms of their use as either single-cell protein (SCP) resources or single-cell oil (SCO) resources, with SCO products being those oleaginous products containing 200 g/kg or more of lipids, whereas those products considered as SCP resources tend to contain more than 300 g/kg of protein (on a dry basis). Both SCP and SCO are now widely being used as protein/amino acid sources, omega-3 sources and sources of bioactive molecules in the diets of several species, with the current range of both these ingredient groups being considerable and growing. However, the different array of products becoming available in the market, how they are produced and processed has also resulted in different nutritional qualities in those products. In assessing this variation among the products and the application of the various types of SCI, we have taken the approach of evaluating their use against a set of standardised evaluation criteria based around key nutritional response parameters and how these criteria have been applied against salmonids, shrimp, tilapia and marine fish species.

This study was performed to determine the effects of dietary supplementation with β-glucan on the growth performance and skin-mucus microbiota of sea trout, Salmo trutta L. in Latvia. The investigations were performed during an eight-month period (September 2018 – April 2019). A total of 15,000 sea trout were divided into five groups. The experimental fish were fed formulated diets enriched with 1 g kg−1 β-glucan (D2), 3 g kg−1 β-glucan (D3), 6 g kg−1 biological product BGN-2 (BGN-2) (D4), and 14 g kg−1 BGN-2 (D5). The control diet (D1) was not supplemented. Our results showed that fish fed diets D4 and D5 achieved significantly (P < 0.05) higher growth parameters compared to those fed the other diets. Pseudomonas and Aeromonas were detected as the main component of fish skin and gill microbiota. Beta-glucan did not affect the skin-mucus microbiota of the sea trout. All isolates were resistant to amoxicillin, ampicillin, cefalexin, and erythromycin and susceptible to gentamicin. The multiple antibiotic resistance index for all isolates was higher than 0.2.
