To through light on the health problems of the fishing in the Ariake Sea and Shiranuhi Sea, we have studied on the hourly working life pattern of fishers and their families, the intensity of each works and the labour conditions of these fishing. According to the type of fishing method, the number of times of fishing and the catches of fishing, the irregularity of the structures of each hourly working life pattern and the special feature of energy expenditure were observed. The relative metabolic rates of each works were estimated to be relatively low, i.e., under 3.0 in most cases, but the R. M. R of the works such as the landing the net (net fishing) and the carrying the fish cases were to be over 4.0 and more. The working times per day were relatively long. Then the total values of energy expenditure of working times were calculated to be 1.000 to 3000 kcal. (the working times were 260 to 900min). Accordingly, the daily energy consumption were estimated relatively high, i.e., 2800 to 3800 kcal. for men. Regarding on the working environment, the cold exposure of the fishing boat in the winter season, the noise of the diesel engine and the vibration of the boat were also worth noticing for the environmental health point of views.
