1998年 5月 17日～ 1998年 6月 6日在福建省连江县苔录镇后湾海域发生一起由裸甲藻等引起的赤潮 ,对鲍鱼养殖业造成严重危害。初步断定 :引起鲍鱼死亡的原因是由于裸甲藻等赤潮生物分泌了某种毒素。并对赤潮在陆上养鲍业上的治理方法进行了研究 ,结果表明 :5～ 2 0mL/m3 甲醛溶液可杀伤甲藻等赤潮生物 ,但不能解体该赤潮生物 ;0 .1～ 0 .5g/m3 KMnO4 可完全治理该种赤潮生物所引起的鲍鱼死亡现象 From May 17, 1998 to June 6, 1998, a red tide caused by Gymnocybe, such as Gymnodinium dunnii, occurred in the back bay of Mogi Town, Lianjiang County, Fujian Province, causing serious harm to abalone farming. Preliminary concluded that the cause of abalone death is due to red algae and other red tide organisms secreted a toxin. The results showed that 5 ~ 20 mL / m3 formalin solution can kill red tide organisms such as dinoflagellates, but can not disintegrate the red tide organisms; 0.1 ~ 0.5 g / m3 KMnO4 completely abolishes the abalone death caused by this red tide creature
