塘坂水库作为福州市区的第二水源地，每年4-10月份频繁暴发以微囊藻为优势种的蓝藻水华．为了控制藻类的大量生长，进一步提高库区水质，本研究采用非经典生物操纵理论，进行现场围隔试验．2012年4-5月，在塘坂水库设置围隔放养不同种类的鱼探索其控藻的效果．结果显示：放养鱼类40天后，放鱼组围隔内浮游植物群落结构发生改变，蓝藻所占比例下降，硅藻和绿藻逐渐增加；同时，放养鱼类促使水体叶绿素-a值升高，藻类小型化．

Tangban Reservoir is the second water source of Fuzhou city .In recent years , from April to October, its water quality is threatened by frequent outbreaks of blue algae blooms , with Microcystin algae as the dominant species .In order to control algae growth and improve water quality in the reser-voir, enclosures experiments were conducted , based on the non-classical biological manipulation theo-ry.During April and May in 2012 , enclosures stocked with different fish species were set up in the reservoir to test their algal controlling effects .Results indicate that , after 40 days of silver carps culture in the enclosures , the phytoplankton community structure changed significantly .In particular , the pro-portion of blue algae went down , with a gradual increase of diatoms and green algae .Meanwhile , fish culture in the enclosures caused a higher value of chlorophyll-a as well as the miniaturization of algae community in the reservoir .
