１９８４～１９８９年，对我国西北地区某些虹鳟鱼养殖场稚鱼大批死亡的病因进行了调查，通过流行病学分析和病原的分离鉴定，确定为传染性胰腺坏死（ＩＰＮ）的暴发流行。１９８７～１９９４年，又着重对ＩＰＮ的综合性防治措施进行了试验研究，提出了漂白粉挂袋消毒，配合药物治疗和加强饲养管理的综合防治方法。有效地控制了ＩＰＮ的发生与流行。通过６年的实际应用，稚鱼的死亡率从９９．６５％～９２．４０％下降到２５．４２％～１４．８２％，即成活率提高到７４．５８％～８５．１８％
From 1984 to 1989, the causes of mass death of juvenile juvenile rainbow trout were surveyed in some rainbow trout farms in northwestern China. Epidemiological analysis and isolation and identification of pathogens were conducted to determine the outbreak of infectious pancreatic necrosis (IPN). From 1987 to 1994, the comprehensive prevention and cure measures of IPN were emphatically studied, and the comprehensive prevention and cure methods of bleaching powder bagging disinfection, drug treatment and strengthening feeding and management were put forward. Effective control of the occurrence and prevalence of IPN. After 6 years of practical application, juvenile mortality dropped from 99.65% to 92.40% to 25.42% to 14.82%, that is, the survival rate increased to 74.58% to 85.18%
