| Outline of Final Research Achievements |
Skin fluke has been a chronic problem in aquaculture. The present study aims to understand the biology and ecology of Neobenedenia girellae and to develop practical methods to prevent infection in fish farms. Larval fluke are positively phototactic and the infection took place during mid-day near the water surface. Shading of culture cage successfully reduced the infection. An adult fluke laid over 700 eggs per day and the eggs accumulated on the culture cages at the maximum rate of over ten million eggs/day. Large proportions of eggs were attached on the upper part of the cages. Using these newly obtained information, we have proposed effective culture techniques to remove eggs from cage and to reduce infection in fish farms.
