The utility of cyanobacterial bloom is often hindered by concerns about the toxin content. Over three years of investigation, we found that the toxin content of cyanobacterial bloom in Lake Taihu was always low in June and higher in late summer and autumn. The findings enabled us to compare the effects of diets containing low and high toxic cyanobacterial blooms on the growth and consumption safety of tilapia. There were no negative effects on the growth of tilapia, and the muscle seemed to be safe for human consumption in the treatment of 18.5% low toxic cyanobacterial bloom. Therefore, limitations of the utilization of cyanobacterial biomass can be overcome by selecting low toxic cyanobacterial bloom that can be found and collected in large lakes.
蓝藻水华的实用性常常受到人们对其毒素含量的担忧所阻碍。经过三年的调查，我们发现太湖蓝藻水华的毒素含量在 6 月一直较低，而在夏末和秋季则较高。这些发现使我们能够比较含有低毒和高毒蓝藻水华的饮食对罗非鱼生长和食用安全性的影响。在处理低毒蓝藻水华（浓度为 18.5%）时，罗非鱼的生长没有受到负面影响，肌肉对人类食用似乎是安全的。因此，可以通过选择可以在大型湖泊中发现和采集的低毒蓝藻水华来克服蓝藻生物质利用的局限性。
