Research Abstract

Fixation protocol has been developed for Chattonella and Heterosigma. We confirmed that this protocol can also apply to naked dinoflagellate of Akashiwo sanguinea. Andthe development of fixation protocol enabled us to analyze cell cycle of these red tide causatives. Using this protocol, field sampling had been carried out for Chattonella and Akashiwo in two hours interval for 24 hours. For Akashiwo sanguinea, we successfully analyzed their in situ growth rate.
