Abstract: To clarify the influence of the annual change of water temperature on resting metabolism in cultured red sea bream under field conditions, oxygen consumption was measured monthly throughout the year. The measurement was carried out at field temperature close to those occuring annually in the nearby fish farm. The annual change of resting metabolism showed a mountainous pattern as the level was higher in summer and lower in winter. The monthly change of the field temperature followed different loci between the season changes toward warmer weather and toward colder weather, and the annual change followed a markedly counter clockwise pattern. When field temperature was approximately the same between the two season changes, the level of metabolism was significantly lower in April and May near the warmer season than in November and December in the colder season. The regression lines were calculated between the field temperature and resting metabolism using natural logarithm value of resting metabolism as the season changes toward warmer weather and toward colder weather. These lines intersected at two points of 10.4℃ and 25.6℃ in field temperature.
