In order to the optimal and upper critical temperature for growth in Sargassum fusiforme collected from Yamaguchi prefecture, we carried out in the boratory culture at 5℃ interval from 5℃ to 35℃ and 1℃ interval from 30℃ to 35℃ under the light intensity of 100μmol photons m^{-2} s^{-1}, respectively. The optimal temperature of main branch in S. fusiforme after 15 days culture was the range of 15 ℃ to 30℃. The upper critical temperature of main branch in S. fusiforme was 32℃.
