Prawns with initial weight (1.27 &plusmn; 0.07 g) and initial length (5.49 &plusmn; 0.09 cm) were stocked in to 200 L aquaria (10 prawns/aquarium), in flow-through water system with controlled temperature, during 60 days. The experimental design was completely randomized with five treatments and four replicates. The diets were formulated to be isoproteic (35.0% CP) and isoenergetic (3500 kcal/kg GE) supplemented with no yeast and yeast derivatives - control, whole yeast - 2.0%, autolyzed yeast - 2.0%, mannanoligosaccharide - 0.2% and &beta;-glucan - 0.2%. Weight gain of prawns fed diet containing mannanoligosaccharide yeast derivative was significantly (P&lt;0.05) higher than prawns fed the others diets. The results indicate that 0.2% of mannanoligosaccharide supplementation provided better growth responses of juvenile <em>M. amazonicum</em>. </font></p><font size="2"><span><p align="justify">KEYWORDS: aquaculture, Amazon River prawn, glucan, mannan.</p></span></font></span> ER -
