夏季为欧洲鳗鲡养殖病害发生的高峰期 ,此期由于持续高温 ,导致水源及养殖池水水温偏高 ,使养殖鳗鲡长期处于不适养殖环境中 ,产生长期持续应激 ,导致体质下降 ;高水温期 ,一些病原体繁殖迅速 ,使养殖环境中病原数量增加 ,侵袭鳗鲡机率增加 ;高温期雷暴雨为主要降雨方式 ,易导

Summer is the peak period of the European eel breeding diseases, due to the continuous high temperature during this period, resulting in high water temperature in the water source and aquaculture ponds, resulting in long-term continuous stress in aquaculture eel, which leads to the decline of physical constitution. In high water temperature, Some of the rapid propagation of pathogens, so that the number of pathogenic bacteria in the environment increased, the probability of invasion of Anguilla increased; high temperature thunderstorms as the main rainfall, easy to guide
