中华绒螯蟹胚胎发育过程中主要生化成分的变化

Biochemical Changes during Embryonic Development in the Crab Eriocheir sinensis

中华绒螯蟹胚胎发育过程中三种主要生化成分中以蛋白质含量最高 ( 44 5 6%～ 67 76% ) ,脂类次之 ( 2 1 32 %～ 34 0 7% ) ,碳水化合物含量最低 ( 0 47%～ 3 0 3% )。从胚胎发育开始至结束 ,蛋白质降低了2 3 2 0 % ,脂类和碳水化合物均没有明显变化。结果表明 。

During the embryonic development of Eriocheir sinensis protein content was the highest, ranging from 44 56% to 67 76%; followed by lipid content, 21 32% to 34 07%; then carbohydrate content, ranging from 0 47% to 3 03%. From the beginning to the end of embryonic development, protein decreased by 23 20%, but proportions of lipid and carbohydrate did not change notably. It is suggest that protein is the main energy source for embryonic development in Eriocheir sinensis.
