水库建成后,由于环境条件的变化,有些鱼类寄生虫因不能完成其生活史而消失,有些种类因环境的适宜而得到发展。因此,研究水库中鱼类寄生虫动物区系的形成及变化,加强对鱼类寄生虫病的防治工作,在水库渔业生产中非常重要。本文就山东省昌潍、烟台、泰安、济南等地、市部分水库有关鱼类寄生虫和鱼病的发生、发展及流行情况和危害程度,作一扼要的阐述。
After the completion of the reservoir, due to the change of environmental conditions, some fish parasites disappear because they can not complete their life history, and some species have been developed due to the suitable environment. Therefore, it is very important to study the formation and change of fauna of fish parasites in reservoirs and strengthen the prevention and control of fish parasitic diseases. In this paper, the occurrence, development, prevalence and harm degree of fish parasites and fish diseases in some reservoirs in Changwei, Yantai, Tai’an and Jinan of Shandong Province are briefly described.
