This study involved to demonstrate changes in chemical composition of Rotifer Brachionus plicatilis (O.F. Muller 1786) fed on three commercial enrichment products. The rotifers were cultured on a mixture of omega 3 algae and omega 3 yeast 60 products. The enrichments of rotifers were made using Red Pepper Paste (ZA), AlgaMac 3050 (ZB) and Spresso (ZC) products. The analysed nutritional compositions before and after enrichment process significantly (p<0.05) changed for crude fat from 6.18 +/- 0.24 to 14.26 +/- 1.22% and for crude protein from 48.24 +/- 0.57 to 59.21 +/- 0.32%, respectively. Crude ash contents were significantly (p<0.05) changed from 6.65 +/- 0.46 to 15.39 +/- 0.39% while no significant difference were seen between the control group of K (concentrated rotifer cultures) and nutritionally enriched groups (ZA, AB and ZC). The ratio of protein: lipid in all experimental groups ranged from 3.47 +/- 0.18 to 9.54 +/- 0.34. Those values were nearly similar for enriched rotifer groups but statistically (p<0.05) being lower that the values of the control-group (K). Of commercial enrichment products AlgaMac 3050 and Spresso were seen to provide effective and efficient results in terms of analysed nutritional compositions.
