优质苗种是养蟹成功的基础。但随着近些年种蟹近亲交配问题的日趋严重,河蟹优良性状和典型形态特征开始出现退化,生产性能降低,加之专业养苗的人技术水平参差不齐,导致蟹苗质量良莠不齐。此时,如何选出优质蟹苗为养蟹成功奠定基础就显得非常重要。目前,鲜有文章专门介绍如何选苗,即使有一些资料谈到如何选择蟹苗,也只是简单的从蟹苗的形态特征、翻身是否有力等简单的方法进行鉴
High-quality seed is the basis of successful crab. However, with the increasingly serious problem of inbreeding of crabs in recent years, the fine traits and typical morphological characteristics of crabs began to degenerate, and the performance of the crabs declined.

At present, there are few articles specifically on how to choose seedlings, even though some of the information on how to choose crabs is only a simple way to learn from the morphological characteristics of crab seedlings,
