三氯异氰尿酸是近几年新开发的一种鱼药。主要用于防治草鱼细菌性肠炎、烂鳃、赤皮三病。我们经过一年的实验,对该药防治草鱼三病的作用和方法有了一点粗浅的认识。一、该药对以草鱼为主的鱼种池有良好的治疗效果。惠民地区大芦湖鱼场1排4号池塘,面积2亩,水深2.2米,放草鱼乌仔1.8万尾,鲢鱼0.7万尾。1989年8月中旬曾出现每天死草鱼种5～8尾。用1袋三氯异氰尿酸(50克)泼洒浸泡小浮萍(稀脉浮萍)喂鱼种,隔天再喂一次,停止死鱼,鱼恢复正常。成本2.5元。二、该药对以草鱼为主的成鱼池亦有显著的治疗效果。博兴县湖滨乡周陈村陈士昌有鱼池5亩,水深 Trichloroisocyanuric acid is a newly developed fish medicine in recent years. Mainly used for the control of grass carp bacterial enteritis, rotten gill, red skin three diseases. After a year of experiments, we have a little superficial understanding of the role and methods of the drug in preventing and controlling grass carp three diseases.

Huimin Dahu Lake fish market 1 row 4 ponds, an area of ​​2 acres, 2.2 meters deep, 18,000 grass turtle Aberdeen, silver carp 7,000. In mid-August 1989 there were 5 to 8 dead dead fish species every day.
