摘要: Abstract The warm-water red tide flagellates Chattonella marina (Raphidophyceae) and Cochlodinium polykrikoides (Dinophyceae) were observed for the first time on west coast of Hokkaido in summer 2014 by daily monitoring surface seawater. two species sporadically appeared warm condition (>20 °C) during a period when Tsushima Warm Current predominated off from July to September. HAB are hypothesized have dispersed naturally with or transported artificially. Our results suggest that occurrences naked such as C. had not been found past systems aiming detect armored toxic dinoflagellates using fixed seawater samples collected along northern Japan. For subarctic sea areas affected climate change, it is concluded freshly sampled, unpreserved important detecting spread water currents Hokkaido, order mitigate potential damage HABs.
