摘要
本文主要报道了中华新米虾（Ｎｅｏｃａｒｉｄｉｎａｄｅｎｔｉｃｕｌａｔａｓｉｎｅｎｓｉｓ）的胚胎发育过程。在水温２２—２６℃的室内条件下，其胚胎发育历时３７６小时。整个发育阶段分为：卵裂期、囊胚期、原肠期、无节幼体期Ⅰ、无节幼体期Ⅱ、无节幼体期Ⅲ和无节幼体期Ⅳ。心脏出现于无节幼体期Ⅱ，并随胚胎发育而表现出心动速率明显加快。复眼出现于无节幼体期Ⅲ．
We studied the embryo development of Neocaridina denticulata sinensis. The total time of the embryo development is 376 hours. The stages of the embryo development are divided into: egg cleavage stage, blastula stage gastrula stage,nauplius stage Ⅰ,naupliusstage Ⅱ,nauplius stage Ⅲ,nauplius stage Ⅳ. The heart forms at nauplius stage Ⅱ. Theheart beat fastly with the embryo development. The compound eye forms at the nauplius stage Ⅲ.
