The crustaceans are one of the largest and most diverse group of invertebrates,which evolved through a complex polymorphic life cycle.As a critical developmental period of crustaceans,embryonic development progresses through orderly and timely thousands of differentially genes activation and expression.However, the molecular genetic programs that respond to embryogenesis and control the process of nutrients utilization in the egg are little known in brachyuran decapods, such as Eriocheir sinensis which was a kind of high commercial aquaculture species in China.
