Rotifers are a valuable and indispensable food source for industrial larviculture and crustaceans worldwide. Rotifers possess several characteristics that make them suitable live prey for newly hatched fish larvae, e.g. relative small size, slow swimming behavior, rapid reproduction
rate, ability to be cultured at high densities1). However, the rotifers are an incomplete food source, because they are low in n-3 highly unsaturated fatty acids, DHA and EPA that are required for survival and successful development of marine fish larvae2). In this study, lipid was extracted from the rotifer by the method of Bligh and Dyer3). The proximate composition of the rotifer were measured to be 63.25% crude protein, 17.77% lipid, 7.72% carbohydrate, 6.54% moisture, and 4.72% ash. Among the fatty acids in the rotifer lipids, palmitic, linoleic,
vaccenic, and stearic acids were the pre-dominant fatty acids, accounting for almost 35.8%, 21.5%, 15.9%, and 7.7%, respectively. The different lipids extracted from the rotifer were isolated including fatty acids, monoacylglycerol, diacylglycerol, and triacylglycerol acids by thin-layer
chromatography. The neutral lipids, glycolipids and phospholipids, were fractionated using organic solvents by silica gel column chromatography. To improve the lipid content, we modified the rotifer lipids by hydrolysis and glycerolysis using lipases such as porcine pancrease and Candida rugosa.
