一、中华绒鳌蟹卵黄磷蛋白的分离、纯化与鉴定目前在判定虾蟹卵巢成熟和卵质时，大多采用性腺指数、蛋白质和脂类的组成与含量等生化指标，尚不够全面。 - Gonadal development and fecundity are affected by certain essential dietary nutrients , especially essential amino acids , essential fatty acids , and vitamins etc . thus , during the last two decades , more attention has been paid to the optimal level of different nutrients in broodstock diets . it is well known that protein is a kind of indispensable nutrient because of its important physiological function on body structure and supplying energy to the growth and development of shrimp and crab . protein and amino acids of broodstock diet have been identified as major dietary factors that determine successful reproduction and survival of offspring
而这些问题的解决则要求对中华绒螯蟹生殖过程中的摄食和消化生理机制，亲体性成熟期对各种必需营养素(如必需氨基酸、必需脂肪酸和维生素等)的需求，卵细胞发生过程中营养物质的合成、转运及贮存规律，以及在受精卵、胚胎和后续以内源性营养为主的?状幼体发育阶段对卵黄磷蛋白的消耗和利用模式等环节进行较为深入的研究，在全面系统地了解中华绒螯蟹的生殖营养生理的基础上，探讨亲体生殖营养对卵质、孵化及后续幼体生长发育的影响。
