Effect of dietary alginic acid on juvenile tilapia (Oreochromis niloticus) intestinal microbial balance, intestinal histology and growth performance

Abstract: The aim of the present study was to assess the effect of a commercial alginic acid source (Ergosan) on tilapia Oreochromis niloticus intestinal microbial balance, intestinal morphology, and growth parameters. Fish were fed a basal control diet or the basal diet plus a source of alginic acid (5 g kg(-1) Ergosan; Schering-Plough Aquaculture, UK) for 9 weeks. At the end of the trial, light and electron microscopy demonstrated that the morphology of the intestinal tract at the gross and ultra-structural level was … Show more

“…Also, Ergosan increased the density of the intestinal goblet cells, villus and fold length in rainbow trout [9] and villus, fold and enterocyte height in tilapia [22]. The results of the current study prove the positive effects of Ergosan (alginic acid) on imaging of the fi sh gastrointestinal morphology.…”

“…Whole body composition of turbots remained unaffected by additive inclusions in both, high and low FM diets as in earlier studies comparing FM-or PP-based diets supplemented with some additives Heidarieh et al, 2012;Kühlwein et al, 2014;Merrifield et al, 2011;Ng et al, 2009). The observed growth decline of fish fed high levels of soy bean and wheat proteins cannot be explained by reduced development of fillet muscles caused by lower protein retention or reduced fat storage.…”

“…Research demonstrated that b-glucan or MOS enriched diets did not improve growth in dentex (Dentex dentex), tilapia, Asian catfish (Clarias batrachus), channel catfish (Ictalurus punctatus), hybrid tilapia (O. niloticus ♀ × O. aureus ♂) and Atlantic salmon (Efthimiou, 1996;Grisdale-Helland et al, 2008;He et al, 2009;Kumari and Sahoo, 2006;Lara-Flores et al, 2003;Welker et al, 2007;Whittington et al, 2005). Moreover, supplementation with brown algae extracts, yeast nucleotides and potassium diformate did not support growth compared to the unsupplemented diets in red drum (Sciaenops ocellatus) and tilapia (Li et al, 2005;Merrifield et al, 2011;Zhou et al, 2009). Refstie et al (2010) proved that supplementation with MOS (2 g kg −1 diet) in a FM reduced diet, containing soy bean and sunflower meal (SBM + SFM) as substitutes, improved growth performance in salmon.…”
