幼体生殖

Fc-vasa mRNAs were detected by RT-PCR in early developmental stages from 2-cells embry to intramembranous nauplius, and not in any stages after nauplius. Based on above results, it is postulated that Fc-vasa is required for germ cell determination and formation of F. chinensis as a maternal component.

但表达量逐渐降低，自出膜后的无节幼体开始检测不到表达信号，根据以上结果推测，Fc-vasa mRNA可能作为母源生殖质成分参与中国明对虾生殖细胞的决定和形成。

We hope that the results could offer reasons for studies of biology of development, genetics and physiology of nutrition in the ontogenetic periods of Coelomactra antiquata and for breeding parents with highquality, regulation of procreation and prevention of damage by disease in "863"project:《Cosmically cultivation of Coelomactra antiquata》.The results showed as below: Distribution and activities of different isozymes in different tissues were differential and relative to their functions.

通过本文的研究，希望可以为更加深入地进行西施舌的发育生物学、遗传学以及幼体发育变态过程中的营养生理学研究提供有价值的参数，同时也为国家"863"计划《西施舌的大规模人工育苗》中优质亲贝培育、生殖调控技术及病害预防等问题提供一定的理论依据。
