微囊藻包括铜绿微囊藻和水花微囊藻,喜生长在温度较高(28~32℃)和碱性较重(p H值8~9.5)的水中,因此多在夏、秋季旺发。当在1升水中有50万个群体以上时,水中溶氧往往不敷其需要,而会自身大量死亡。藻体死亡后,向水中释放大量毒素,对鱼类生长非常不利,甚至毒死鱼类。防治方法:(1)经常加注新水,不使水中有机质含量过高,注意水的p H值调节(定期泼洒生石灰)可控制微囊藻
Microcystis, including Microcystis aeruginosa and Microcystis aeruginosa, grows well in the higher temperature (28 ~ 32 ℃) and alkaline (p H value 8 ~ 9.5) of the water, so much in the summer and autumn flourishing . When there are more than 500,000 people in a liter of water, the dissolved oxygen in the water often does not meet its needs and will die in large numbers on its own. After the death of the algae, a large amount of toxins are released into the water, which is very unfavorable to the growth of the fish and even poison the fish. Prevention and treatment methods: (1) Often add new water, do not make the organic matter content is too high, pay attention to the water p H value regulation (regular splash lime) can control Microcystis
