蓝藻“水华”和海洋赤潮被专家并称为水体“生态癌症”。目前国内普遍采用鲢、鳙鱼除藻法,但由于这两种鱼对蓝藻消化率只有20％,且排泄出的粪便会再次繁殖蓝藻,治理效果不尽如人意。为此,科学家经反复试验攻关,筛选出罗非鱼作为除藻鱼种。这种鱼不仅对蓝藻消化率达70％,而且对蓝藻毒素分解能力也远远强于鲢、鳙鱼。经检测,月湖中放养罗非鱼的芳草洲水域和只养鲢、鳙鱼的其他水域相比,蓝 Cyanobacteria “bloom” and marine red tides by experts and as water “ecological cancer.” At present, silver carp and bighead carp algae are widely used in our country. However, since the two kinds of fish have only 20% digestibility of cyanobacteria, excreted excrement will reproduce cyanobacteria again and the treatment effect is not satisfactory. To this end, scientists repeatedly test tackling, screening out tilapia as algae species. This fish is not only the digestibility of blue-green algae 70%, but also the ability of cyanobacteria toxin decomposition is far stronger than silver carp, bighead carp. After testing, the month Lake stocking tilapia Fangcaizhou waters and only raised silver carp, mandarin fish compared to other waters, blue
