The proximate composition of four egg stages and 1st zoeal stage of Macrobrachium idella idella were investigated. The protein content of egg was gradually decreased from egg stage-1 (69.32%) to egg stage-IV (54.56%) and the protein content in Ist zoeal stage was found to be 52.42%. The carbohydrate content increased from egg stage-I (3.24%) to freshly hatched Ist zoea. Lipid values showed a decreasing trend from egg stage-I (15.86%) to freshly hatched Ist zoea (4.82%). The water content uniformly increased from egg stage I (62.26%) to freshly hatched Ist zoea stage (79.68%). Among total 9 individual saturated fatty acids reported, the palmitic acid (C16:0) was maximum in all egg stages and in Ist zoea. Which is followed by stearic (C18:0) and myristic (C14:0) acids. The total essential amino acids were showed increasing trend from the egg stage I to IV. However they were little bite .. View More»
