中华绒螯蟹是我国水产养殖上的主要养殖品种之一 ,但其苗种供应和成蟹产量仍不稳定 ,特别是大规格成蟹产量非常低 ,这成为河蟹养殖的一个制约因素。对河蟹消化酶的研究 ,有助于揭示河蟹在各个养殖阶段和环境下的营养需求特点。关于蟹类消化酶的研究 ,仅在幼体方面有些报道 ,如H Chinese mitten crab (Eriocheir sinensis) is one of the major cultured aquaculture species in China, but its seed supply and crab production are still unstable. Especially, the production of large-sized crabs is very low, which becomes a constraint factor for crab farming. The research on the digestive enzymes of crabs helps to reveal the nutritional requirements of crabs in various breeding stages and environments. About crab digestive enzymes research, only some reports in the larvae, such as H.
