Abstract：
There is an urgent need to establish protocols on how to protect salmonids in aquaculture from outbreaks of proliferative kidney disease (PKD). For this purpose, systems for a continuous application of peracetic acid (PAA, 0.1 mg l-1) and of ultraviolet C light (UV-C, 323.5-158.6 mW s cm-2) were installed in the inlet of raceway-channels within a sub-unit of a commercial rainbow trout Oncorhynchus mykiss farm. After 127 d of rearing, a fish health examination was conducted. Fish in the control and PAA treatment groups showed signs of PKD. In contrast, fish in the UV-C treatment group showed almost no signs of disease based on clinical examinations and necropsy. This observation indicates that UV-C irradiation could be a promising tool to protect fish from PKD in the future.
摘要：
迫切需要建立有关如何保护水产养殖中的鲑鱼免受增生性肾脏疾病（PKD）暴发的协议。为此,用于连续应用过乙酸(PAA，0.1mgl-1）和紫外线C光（UV-C，323.5-158.6mWscm-2）安装在商业虹鳟鱼Oncorhynchusmykiss农场子单元内的跑道通道入口中。经过127d的饲养，进行了鱼类健康检查。对照组和PAA处理组中的鱼显示出PKD的迹象。相比之下,根据临床检查和尸检，UV-C治疗组中的鱼几乎没有疾病迹象。这一观察结果表明，UV-C辐射可能是未来保护鱼类免受PKD侵害的有前途的工具。
