Research Abstract

In a seaweed bed of Ago Bay, central part of Japan, cell abundance (density of the cells attached to macroalgae) of Gambierdiscus sp. was monitored monthly. The abundance of Gambierdiscus sp. increased in warmer season (especially from August to October). On the other hand, although the cell density was very low, they also occurred even in the cold season (from January to March). The results of growth and survival experiments, using the Gambierdiscus sp. strains isolated form Ago Bay, against temperatures in the laboratory well explained the seasonal changes in abundance of this species in the bay.
