“…Therefore, this strain of yeast can be used as a growth promoter and immune stimulant in some fish species (Siwicki et al 1994;Sakai 1999;Oliva-Teles and Gonçalves 2001;Li and Gatlin 2004). In the poultry industry, S.C. has been used as general performance promoter and anti-mycotoxin because of its adsorbent effect on AFB 1 (Celik et al 2000;Celyk et al 2003).…”

Aflatoxicosis, toxicity of aflatoxin, is of great concern in aquaculture. This study was conducted to assess the efficacies of three adsorbents, a hydrated sodium calcium aluminosilicates (HSCAS), Saccharomyces cerevisiae (S.C.) and an esterified glucomannan (EGM), against feed contaminated with contained 200 lg/kg (ppb) aflatoxin B 1 (AFB 1 ). A total of 240 Nile tilapia fingerlings, Oreochromis niloticus (15 ± 2 g), were randomly divided into eight experimental groups (30 fish per group) with three replicates. Group T 1 represented the negative control fed on a basal diet, and T 2 was the positive control group fed on a basal diet supplemented with 200 ppb AFB 1 . Groups T 3 , T 4 and T 5 were fed the AFB 1 -contaminated diet (200 ppb) supplemented with 0.5 % HSCAS, 0.25 % S.C or 0.25 % EGM, respectively. Groups T 6 , T 7 and T 8 were fed a basal diet supplemented with 0.5 % HSCAS, 0.25 % S.C or 0.25 % EGM, respectively. The reduction in AFB 1 -bioavailability was judged by toxin residues in fish musculature throughout the study beginning at the second week of exposure. AFB 1 reduced the survivability, total weight gain, average daily gain and specific growth rate, evident as early as the second week of exposure. The total erythrocyte count, hemoglobin content and total leukocyte count were significantly decreased after AFB 1 exposure for 6, 8 and 10 weeks, respectively. Prolonged administration of AFB 1 led to significant increases in serum alanine transaminase, aspartate transaminase and creatinine activity, and produced significant decreases in plasma proteins, including serum globulin. The specific immune response was assessed by an agglutinating antibody titer after immunization of the fish with an Aeromonas hydrophila vaccine. The antibody titer and relative level of protection of fish challenged with Aeromonas hydrophila 123Aquacult Int (2014( ) 22:523-540 DOI 10.1007 were reduced throughout the period of examination in AFB 1 -exposed fish. Supplementation with HSCAS, S.C. or EGM significantly improved growth performance, blood parameters and immune status; in addition, these groups showed decreased AFB 1 residues in fish musculature when compared with AFB 1 -treated fish. HSCAS effectively reduced AFB 1 toxicity, whereas S.C. and EGM were less efficacious.

“…Brewer's yeast has been recognized to have potential as well as a substitute for live food in the production of certain fish or as a potential replacement for fishmeal [88][89][90]. In addition, it has low content in phosphorous, meaning less water and environmental contamination than common fish meal and other plant-based alternate protein sources [91].…”

“…Traditionally, alternatives to protein meals have been sought from vegetable sources such as soybean meals (Soltanet al, 2001), cottonseed meals (Abdellaet al, 2008 andSoltanet al 2011 a&b), sunflower meal (Soltanet al, 2015), linseed and canola seed meals (Soltan, 2005 a&b) due to their wide spread availability, relatively favorable amino acid profiles, reduced cost and sustainable nature (Hardy, 2010). However, the inclusion of plant based proteins in aquafeeds provides a number of problems which include the occurrence of antinutritional factors, reduced digestibility, lower palatability and limitations of certain essential amino acids (Oliva-Teles and Gonçalves, 2001). …”

A feeding trial was conducted to study the possibility of replacing the fish meal (FM) with fermented fish by-product silage (FBS) as non-conventional ingredients in the diets of the Nile tilapia, Oreochromis niloticus fingerlings. Five isonitrogenous (300 g CP kg -1 dry matter, DM) and isocaloric (19 MJ gross energy kg -1 DM) diets were formulated and FM was replaced by FBS in five increased levels, 0, 25, 50, 75 and 100% g to formulate the five experimental diets, FBS0, FBS25, FBS50, FBS75 and FBS100, respectively. Three hundred O. niloticus fingerlings (18.53±0.70g) were randomly distributed into 15 glass aquaria (160 liter), and were divided into five groups (three aquaria for each group) and each aquarium holding 20 fish. Experimental fish were fed onon the formulated diets for 84 days. Replacing of FM with FBS up to 25% did not significantly (P<0.05) affected growth and feed utilization parameters, while the other substitution levels (50,75 or 100%) significantly (P<0.05) reduced growth and feed utilization parameters. Fish offered the control diet exhibited the highest significance (P<0.05) average body weight (BW), body length (BL), weight gain (WG), specific growth rate (SGR), feed conversion ratio (FCR) and protein efficiency ratio (PER). Fish group fed onon FBS25 gained the highest significant protein content and the lowest fat and ash content of carcasses compared to the control and the other fish groups Generally, replacing 25% of FM by FBS did not significantly affected growth and feed utilization parameters and reduced feed costs by 7.93% for tilapia fingerlings.
