  蓝藻,是一个老生常谈的对象,很多研究者和生产一线工作者都对其进行了大量的研究,得出了许多有效的龙虾养殖技术治理方法。但是每年仍有许多龙虾养殖者在水草养殖实践中,不能够及时的进行治理。

  蓝藻毒素通过其危害方式可分为肝毒素和神经毒素,它们是已知的会侵袭肝脏和神经的毒素,另一类毒素对皮肤有刺激作用。蓝藻中个别种活体带毒,如蓝藻中的项圈藻可快速产生致死因子,破坏养殖对象的鳃组织,干扰其新陈代谢的正常进行,麻痹神经,使水塘虾死亡;大部分蓝藻死亡个体也会分解产生蓝藻毒素(如微囊藻毒素)。蓝藻毒素量多时可直接造成养殖对象中毒死亡;或者即使数量少,也可通过食物链积累效应危害养殖对象,直至危害人体。

  1、水体富营养化,氮磷比失衡。蓝藻自身具有固氮作用,因此水体中氮的含量对其生长影响不大,但是磷却是来源水体,因此,富营养化的水体中,含磷丰富的蓝藻生长更快,影响小龙虾苗的生长。
