Some foundamental researchs upon bacterial contamination of wooden fishing boats (less than 100 tons) were carried out and the effect of a germicidal lamp upon the sterilization of bacteria was studied. 1) The bacterial densities were examined in several parts of the fishing boats, which had been thoroughly washed after unloading of the catch. And, in the fish hold, which has been most frequently in contact with the catch, the density was counted more than 10^6 per cm^2. 2) The bacterial density calculation shows the existence of a close relationship between the efficiency of washing and the wall materials or wall paints of the fish hold. The material which shows the best effect is a galvanized iron, the second best is the one coated with vinyl chloride paint or coal tar, while, in case of plain wooden wall, the effect could be barely observed. 3) The installation of a germicidal lamp in the fish hold was proved to be very effective in sterilizing the bacteria on the wall. This result probably be attributable to the fact that most of the bacteria in the fish hold consist of non-sporing species which have weak resisting capacity to the ultra violet ray.
