中华绒螯蟹幼蟹的维生素C摄取与克服性早熟

To Absorb the Vitamin C from the Young Crabs of Eriocheir Sinensis and Overcome Pubertas Praecox

中华绒螯蟹人工培育幼蟹过程中，缺少必需的维生素C的添加，会导致约14％左右的雌性个体性早熟出现。正常幼蟹的肝胰脏、肌肉的维生素C含量高于早熟幼蟹1～2倍。性早熟现象与其体内Vc的含量不足存在着正相关。初步判断，Vc源的缺乏或不足是造成幼蟹性早熟的重要原因。饵料中Vc的添加，对幼蟹克服性早熟与促进生长有明显的作用，适宜的添加量为3000～5000mg·kg－1。
