| The effects of environmental eonditions on germination of Alexandrium tamarense cysts were examined. The cysts were isolated from the sediment samples collected from Masan Bay. Germination success was measured by the incubation of cysts under the laboratory conditions and compared in different water temperatures, salinities, and sediment depths. The highest germination rate was recorded at $15^{circ}C$ and relatively higher germination rate was observed at $10^{circ}C$ above, while little or no germination occurred at 20 to $25^{circ}C$. Light and salinity affected little on the excystment. Germination rate according to the sediment depths was higher in the lower layer (5¡10 cm) than in the upper (0¡2 cm) of the sediments collected in March, while higher in the upper than the lower in November. :Based on these results, water temperature seems a principal factor controlling germination of A. tamarense in Masan Bay. |
