小三毛金藻是一种微型单细胞金藻。由于它在盐度较高的北方盐碱地池塘、沟湾等水域极易大量繁殖,分泌毒素,造成养殖鱼虾的大量死亡。近几年来,山东、河北等省相继发生过小三毛金藻大量繁殖造成的淡水养殖业危害。1989年以来,我们通过反复试验,初步探索出了小三毛金藻危害规律及有效的防治方法。 Small three golden algae is a micro-single-cell gold algae. Because of its salinity in the northern salt ponds, ditches and other waters easily multiply, secrete toxins, resulting in a large number of fish and shrimp deaths. In recent years, Shandong, Hebei and other provinces have occurred in a large number of small red clover Chrysomellum breeding freshwater aquaculture hazards. Since 1989, we have tentatively explored the harmful effects of Chlamydomonas reinhardtii and the effective control methods through repeated experiments.
