Ecophysiological Studies on the Population Dynamics of Two Toxic Dinoflagellates Alexandrium tamarense and Alexandrium catenella Isolated from the Southern Coast of Korea -I. Effects of Temperature and Salinity on the Growth

Effects of temperature and salinity on the growth of the toxic dinoflagellate and isolated from the southern coast of Korea were examined in the laboratory. Growth experiment was conducted under the following combinations of temperature and salinity; 10, 15, 20, 25 and , 10, 15, 20, 25, 30 and 35 psu at a constant irradiance of 300 photons . Temperature and salinity conditions for maximum growth rate were indicated as follows: temperature and salinity 30 psu (0.31 ) in , temperature and salinity 30 psu (0.36 ) in A. catenella. Temperature and salinity ranges for optimum growth condition of two species were , 25~35 psu and , 25~35 psu, respectively. The result of two-factor ANOVA indicated significant effects (P
