摘要
在６口海水土池（计１．９ｈｍ２）中分别按下列密度（万／ｍ３）布苗：３，４，５，３，４和０．２７，比较研究了中华绒螯蟹（Ｅｒｉ－ｏｃｈｅｉｒｓｉｎｅｎｓｉｓ）Ⅰ期氵蚤状幼体（Ｚ１）的密度对幼体变态率和成活率的影响。结果表明，Ｚ１的密度为４万／ｍ３时，大眼幼体的变态率（大眼幼体密度占Ｚ５密度的％；２１．６％）和成活率（大眼幼体的密度占Ｚ１密度的％；２．４％）及产量（４２ｋｇ／ｈｍ２）最高。
Six earthern ponds with each surface area of 2160m 2-4292m 2(total 1.9ha)were stocked with zoea I of Chinese mitten crab at a rate of 30000,40000,50000,2700.30000,40000 individuals/m 3 respectively for investigating it's optimum stocking density of zoea I.It was found that 40000 zoea I/m 3 was the optimum density,and the highest survival rate(2.4%)of zoea I and yield (42kg/hm 2)of megalopa were obtained.
