“…Dimitroglou et al (2010) did not find any difference ( P>0.05) between control group and MOS supplemented groups in juvenile sea bream (Sparus aurata). In adult sea bream, Gü ltepe (2007) reported an increase in growth rates within the MOS-fed groups.…”

The study investigated the effect of increasing dietary inclusion of M annan oligosaccharide (M OS) on growth and blood parameters of sea bream (Sparus aurata). Varying concentrations of M OS were added to commercial sea bream feed at 0‰ (control), 1, 2, 3 and 4‰. At the end of the 15 week trial, control group had the highest final weight, specific growth rate, feed conversion ratio and protein efficiency ratio (P<0.05), although these did not differ among the M OS containing groups (P>0.05). Survival rates were higher in the M OS treatment groups. Blood parameters, did not differ among treatment groups (P>0.05). The lowest alkaline phosphatase (ALP) value was measured in the control group whereas the highest was recorded in the 4‰ M OS group. The lowest level of triglycerides was measured in the 4‰ M OS group, while the highest level of triglycerides was measured in the control group. Cholesterol level was lowest in the 2‰ M OS group (P<0.05). The study showed that the inclusion of dietary MOS has no negative effects on growth and blood parameters in sea breams. However, dietary M OS inclusion led to higher survival rate in trial fish.

“…Mannan oligosaccharide as nutritional supplements was found to be able to improve gastrointestinal health, overall health as well as wellbeing, energy levels and performance. Dimitroglou et al (2010) showed that mannan oligosaccharide incorporated into live feeds retarded Vibrio species levels and could improve fish health and production. They also reported that mannan oligosaccharide improved growth performance and feed utilization in gilthead sea bream.…”

Abstract:A study was conducted to determine the efficacy of three most commonly used growth promoters from different pharmaceutical companies on growth performance of hybrid walking catfish (Clarias batrachus × Clarias gariepinus). The experiment was done in the wet laboratory of the Department of Aquaculture, BAU, Mymensingh, with a total of 10 aquaria and 160 fish having mean initial weight of 6.3 ± 0.48 g. The three growth promoters, "Charger gel" from Fishtech (BD) Ltd., "Growth gel" from Advance Agrotech (BD) Ltd. and "Hepaprotect-aqua" from Renata Animal health Ltd., were used in separate nine (9) aquaria at recommended, lower dose and higher dose respectively. One aquarium was used as control (diet without any growth promoter). The fish were fed with paragon nursery floating feed at 20% of body weight in each aquarium for 28 days. Doses of Charger gel were given as 80, 60 and 100 mg/20 g feed/day, that of Growth gel, 0.14, 0.12 and 0.16 ml/20 g feed/day and of Hepaprotect-aqua, 30, 15 and 50 mg/20 g feed/day. Re-circulatory system was used throughout the experimental period. By applying recommended, lower and higher dose of "Charger gel", mean final weights were found as 23.0, 21.9 and 35.9 g; average daily weight gain as 0.60, 0.56 and 1.06 g and specific growth rate (SGR) as 2.01, 1.93 and 2.70% respectively. For "Growth gel", mean final weights were found as 22.8, 17.3 and 31.1 g; average daily weight gain as 0.59, 0.39 and 0.88 g and SGR as 1.99, 1.57 and 2.48 % respectively. For "Hepaprotect-aqua", mean final weights were found as 24.2, 17.5 and 28.2 g; average daily weight gain as 0.64, 0.40 and 0.78 g and SGR as 2.09, 1.58 and 2.32% respectively. In all the cases survival rates were 100%. All the three growth promoters showed better results at their higher doses in comparison to their results in lower and recommended doses. However, in average Charger gel showed the best result than the other two growth promoters. This information on the efficacy study of growth promoters needs to be disseminated to the farmers for improved fish production.

“…2009). Such enteritis effects have routinely been described in fish with the use of light microscopy (for review see Krogdahl et al, 2010) but considerably fewer studies have utilised electron microscopy to observe ultrastructural changes Merrifield et al, 2009;Dimitroglou et al, 2010). Such histological and morphological changes which result in damaged enterocytes and exposed intracellular tight junctions may help explain previous observation of increased susceptibility of SBM fed fish to pathogenic infection .…”

“…BakkeMcKellep et al 2007b;Merrifield et al, 2009;Dimitroglou et al 2010) and several studies have observed sensitivity of the gut microbiota of fish to different dietary lipid levels (Lesel et al, 1989; and different dietary plant oils (Ringø et al, 2002;Montero et al, 2006). However, to our knowledge only one study has assessed the effect of dietary SBO on the gut microbiome of fish.…”

“…However, some information is available. Dimitroglou et al (2010) assessed the gut microbiota of gilthead seabream fed diets with or without mannan oligosaccharides (MOS) in both FM and SBM (solvent extracted, included at 31.3%) diets. PCR-DGGE analysis revealed clear differences in the allochthonous microbial communities, reflected by cluster analysis from dendrograms (depicting low similarity between treatments) and by higher species richness (increased observable phylotypes; FM = 14.5 ± 0.7 vs SBM = 25.0 ± 0.0), microbial diversity (shannon weaver index; FM = 2.65 ± 0.05 vs SBM = 3.17 ± 0.01) and higher similarity between replicates (SIMPER; FM = 84.79% vs SBM = 92.25%).…”
