ABSTRACT

The flora and phenology of marine algae in Yongil Bay and its adjacent areas, the eastern coast of Korea, were investigated seasonally at four sites during May 1996- February 1997. A total of 116 alga l species-14 greens, 26 browns and 76 reds-was identified. Seasonally, they were 67 species in spring, 63 species in summer, 59 species in autumn, and 64 species in winter, respectively. The composition of algal species of the bay was more or less simpler than that of its adjacent areas, since 85 species were occurred at sites inside the bay and 103 species outside the bay. The values of R/P and (R+C)/P ratios of vegetations were 2.9 and 3.4 in both inside and outside the bay, respectively. This shows that the flora and phenology of marine algae of this area is a mixed one close to the temperate flora. Comparing the result of this study to that of 10 years ago, the number of common 35 species of four sites including 6 green, 10 browns and 19 reds, were not changed much from 31 species of the past. Twenty species among them were occurred again in this investigation.
