拟议的规划活动将探讨基本的 关于使用期间的精力充沛的战略问题 半深海蟹的早期发育 具体问题将 解决的问题包括：1）。不同国家的贡献是什么 脂质类、蛋白质和碳水化合物， 在深海红胚胎发育过程中的要求 蟹Chaceon quinquedens;和2）.有哪些贡献 母亲营养史和深度（或温度） 中华绒螯蟹卵黄利用规律的研究 胚胎 我的初步研究表明这个物种 呈现出两种不同的蛋黄组成模式， 在胚胎发生过程中的利用。 这一拟议规划 活动旨在确定造成 对于观察到的变化，并将作为基础， 更详细的胚胎营养比较研究 两种半深海蟹，红蟹和 金蟹角芬内里，有不同的地理和 水深分布

The proposed planning activities will investigate fundamental questions concerning the energetic strategies utilized during early development of bathyal crabs. Specific questions to be addressed include: 1). what are the contributions of different lipid classes, protein, and carbohydrate toward nutritional requirements during embryonic development of the deep-sea red crab Chaceon quinquedens; and 2). what are the contributions of maternal nutritional history and depth (or temperature) of occurrence to the patterns of yolk utilization in red crab embryos. My preliminary work demonstrates that this species exhibits two different patterns of yolk composition and utilization during embryogenesis. This proposed planning activities are designed to determine the factors responsible for the observed variation and will be used as the basis for a more detailed comparative study on embryonic nutritional flexibility in two species of bathyal crabs, red crab and golden crab C. fenneri, which have different geographic and bathymetric distributions.
