The age and growth pattern of Myagropsis myagroides(Cystoseiraceae, Phaeophyta) population were investigated at Tongyeong (128°25′E and 34°45′N) in South coast of Korea, from September 1998 to August 1999. Water temperatures varied from 7.7℃ to 26℃ during the survey period. Distinct seasonal changes were found in the plant length and wet weight of plant, and their maximum length and wet weight were attained 70.5(±20.9) cm and 191.8(±135.0)g during April and May. The growth patterns were divided into four periods of slow growth (September-November), fast growth (December-February), maturing growth (March-May) and declining period (June-August). The Tongyeong population of M. myagroides was dominated by less than three-year old small plants with slower growth rates, shorter plant length, lighter plant weight than those of other locations in Korea.
