Abstract

Abstract

This paper mainly studied the process of the external morphological character of Cherax qudricarinatus embryo from fertilization to incubation.This process is divided into cleavage stage,blastula,gastrula,egg-nauplius stage,egg-metanauplius stage,embryo with eye pigments formed stage and prehatching stage.The larval is similar to the adult on the morphological structure while it just has hatched.The whole incubation period of this species at 28 ℃ is about 39 days.
