This report analyses the amount and nutritional composition of edible parts muscle, reproductive glands and liver in Scylla serrata .The results show: Total edible parts in male and female crabs take about 64% of the body weigh. Among the total edible parts, liver takes about 10 75%, reproductive glands take 16 52%(in female) or 1 83% (in male), muscle takes 59 30% (in female) or 70 84% (in male). Female's reproductive gland contains the lowest water (54 69%) and the highest protein (30 59%). The amino acids score of female's reproductive gland is as high as 93 58. Fat in muscle is lower (0 82%) than that in the other organs (liver 15 68%, female's reproductive gland 14 50% and male's reproductive gland 1 27%). Compared with the other organs , UFA、PUFA and EPA、DHA in fat of muscle were highest (74 58%、47 83%、18 04%、13 52%). It contains 2 72g ash and 580mg Ca per hundred grams in liver. It is higher than that in the other parts. All edible parts contain high K and low Na, Se takes at least 110 μg or more than that amount. Every hundred grams of the female's reproductive gland contain 766 16mg cholesterol.
