| 摘 要： | 采用♀亲蟹平均规格分别为158.9g、132.8g,♂亲蟹平均规格为180g、150g两种群体繁育的蟹苗培育的1龄蟹种,其群体规格分别为128只/kg、160只/kg。在面积相同、放养密度相同、饲养条件相同的条件下,采用天然海水土池繁育的蟹苗培育的1龄蟹种成活率为5.1%、亩产蟹种8064只;而采用天然海水工厂化繁育的蟹苗,育种成活率为2.24%、亩产蟹种3609只;在蟹苗来源相同、饲养管理相同,培育池面积为19亩的培育池蟹种产量低于面积5亩的池塘。

| Abstract: | The results showed that the average size of seedling grown from fry was 128 and 160 seedlings per kilogram,respectively,when the average body weights of crab parents were 158.9g and 132.8g for female,and 180g and 150g for male.Under the same conditions of area,stocking density and rearing method,survival rate from fry to seedling was 5.1% ,which the fry was produced in natural seawater pond,and 8064 seedlings per mu were obtained.And survival rate was 2.24%,which the fry was produced in natural seawater factory,and 3609 seedlings per mu were obtained.Under the same conditions of fry and breeding management the seedling production in 19 mu of culturing pond was lower than that one in 5 mu. |
