一、由蓝藻引起的中毒1、病因由于池塘中大量微囊藻产生有毒物质而引起鱼类中毒。池中微囊藻的主要种类是铜绿微囊藻和水花微囊藻。这些藻类在盛夏和初秋天气炎热时,经常会在水面形成一层翠绿的水花,养鱼户称之为“湖靛”。当这些藻体死后,其蛋白质分解产生羟胺及硫化氢等有毒 First, caused by cyanobacteria poisoning 1, the cause of the pond as a large number of microcystins produce toxic substances caused by fish poisoning. The main types of Microcystis in the pond are Microcystis aeruginosa and Microcystis aeruginosa. These algae often form a layer of verdant water on the surface of the water during the hot summer and early autumn. Fish farmers call it “the lake.” When these algae die, the protein is decomposed to produce hydroxylamine and hydrogen sulfide and other toxic
