초록

To understand growth characteristics of eight dominant red tide species (Prorocentrum minimum, Heterocapsa triquetra, Scrippsiella trochoidea, Akashiwo sanguinea, Chattonella marina, Heterosigma akashiwo, Amphidinium carterae and Rhodomonas salina) in the Korean coastal water, the growth rates were examined in relation with the impacts of water temperature and bio-volume. Of these, P. minimum, C. marina, H. akashiwo, A. carterae and R. salina were eurythermal species with relatively high growth rates in a borad ranges (15 to 25􀆆C) of water temperature. On the other hand, the growth rate of H. triquetra, S. trochoidea and A. sanguinea were high in relatively mid temperature (optimum: 25􀆆C) condition. In particular, H. triquetra was well adapted in low temperature of 5 to 15􀆆C, implying that the species can survive and grows even at very low temperature. Based on results of our experiment, the growth characterestics of five eurythermal species and three mid temperature species may have dominated in Korean coastal water during summer season and fall season, respectively. Contrastively, the growth characteristics of H. triquetra make a consistently dominant during the cold winter season. In addition, the growth rates of large bio- volume species were lower than those of small bio-volume species, indicates that growth of single cells of several flagellates might be depended on the cells sizes.
