我国五十年来海洋动物发育与 繁殖生物学的研究进展

我国在海洋动物发育与繁殖生 物学方面的研究是随着国民经济的迅速发展而起步的，并且在某些方面已取得了举世瞩目的 成就。作者着重对我国近50年来，海洋经济动物的发育和繁殖生物学研究作一综述。

Advanced in the Developmental and Reproductive Biology of Marine Animal during the Past 50 Years in China

This paper reviews the achievements in developmental and reproductive biology of marine economic animals since the establishment of the People's Republic of China. The first achievements are the studies of embryo nic development of amphioxus by professor Tong Dizhou (the famous experimental e mbryologist in China) and his collaborat ors in the 1950's to 1990's. The second ones are the studies on the development, habits and characteristics of shipworm s, as well as reproduction in advance and raising seedlings indoor by professor Wu Shangqin (the famous embryologist of marine animal in China) and her collabor ators at the end of 1950's to the beginning of the 1960's. In the 1960's, Zhao F azhen (academician of Academy of Sciences in China) and his collaborators resear ched larval development and artificial seedling of Penaeus chinensis. In fis h, the main studies were focused on embryonic development, ultrastructure of spe rm in a variety of fish. In crustacea, the main researches were centralized in l ife history, reproductive habits and characteristics, genesis of germ cells and impregnation biology in economic prawn, crab and atemia. The life history, devel opmentl of gonad, genesis and ultrastructure of germ cells were studied of some economic seashells.
