In recent years, it has been found that not only in small bodies of water, some species can be harmful to adult fish in flood conditions. In this paper, the basic biological characteristics of finger worm and its prevention and treatment of new technologies are reviewed. First, the biological characteristics of ring worm disease and life history Ring worm is the most common monkeys in fish. The ring worm’s life cycle is fertilized eggs - hatching - larvae - parasitic - adult - fertilization
