秋季既是鱼体生长最快,又是鱼病高发季节。鱼塘经过大量的投饵、施肥,有机腐殖质增多、病原菌大量繁殖,加上高温(水温超过33℃时对鱼体生长有影响)、缺水、鱼口密、活动空间小,极易引起鱼病发生。连日来,笔者已接到十几宗鱼病发生死亡的投诉,并到现场观察,死亡最多的是鲮鱼、鲢、鳙、草鱼和土塘虱,其它名优品种(甲鱼)也有死亡。为了搞好秋季养鱼综合措施,做好鱼病防治:一是要生态防病;二是对水质、饵料和网(工)具进行全面彻底的消毒,杀灭病原体,切断 Autumn is the fastest growing fish, but also the season of high incidence of fish disease. After a large number of fish ponds, fertilization, increased organic humus, large numbers of pathogenic bacteria, coupled with high temperatures (when the water temperature exceeds 33 ℃ affect the growth of fish), water, fish mouth dense, small space activities, can easily lead to fish Disease occurs. In recent days, the author has received more than a dozen complaints about the death of fish diseases and observed the scene. The most dead were catfish, silver carp, bighead carp, grass carp and earth louse, and other famous breed (turtle) also died. In order to improve the comprehensive measures for fish farming in autumn, do a good job in the prevention and treatment of fish diseases: First, to ecological disease prevention; second is the water quality, food and net (workers) with a full and complete disinfection, kill pathogens, cut off
