Key HAB contributions

Yasuwo Fukuyo’s interest in dinoflagellates was sparked by PSP events in Ofunato Bay in the 1960s and 1970s, which had been tentatively attributed to a ‘Gonyaulax’ species. All the important HAB discoveries of the late 1970's in Japan required teamwork by chemists, taxonomists, toxicologists and Yasuwo was the taxonomist who guaranteed correct morphotaxonomy of the causative organisms, including the first identification of Dinophysis fortii as the causative agent of DSP, and description of the new species Gambierdiscus toxicus as the causative agent of ciguatera. Other HAB species such as Ostreopsis ovataO. lenticularis, Alexandrium affine, A. hiranoi; A. satoanum, Prorocentrum concavum, P. emarginatum, P. vietnamensis were all first described by him.

He also was instrumental in organizing the research team to Vietnam which discovered the ASP producing diatom, Nitzschia navis-varingica. Yasuwo is a “roving professor”, with a record of ‘frequent flyer miles’ and enthusiastically teaching innumerable courses in diverse lands such as Japan, Malaysia, Philippines, Thailand, Indonesia, Vietnam, Brunei Darussalam, Korea, China, Kuwait, Mexico, Guatemala, Mauritius and Denmark. His miming of living cells, their flagellar activities and flawless pronunciation of Dinophysis lapidistrigiliformis are unforgettable. He is quick to make fun of himself and is well liked by lady scientists in South Asian countries who affectionately call him "uncle Fukuyo", because he is kind and friendly to everyone.

Yasuwo has been a key figure in the organization of many training courses, conferences, and workshops, at the IOC-WESTPAC Scientific Symposia on Marine Science, the International Conferences on Molluscan Shellfish Safety, and International Conferences on Harmful Microalgae. He served an advisor to the Japanese Delegation to the Marine Environmental Protection Committee (MEPC) of the International Maritime Organization (IMO) for the development of the International Convention for the Control and Management of Ship’s Ballast water and Sediments, and the International Measures for Minimizing the Transfer of Aquatic Invasive Aquatic Species through Biofouling of Ships. He played a leading role in the establishment of IOC-HAB Programme from its early beginnings and supported its activities as Japan’s delegate to the Intergovernmental Panel meetings on Harmful Algal Blooms (IPHAB), the IOC Executive Committee, and IOC General Assembly. He also served on the Science Steering Committee of the IOC SCOR Programme Development for Harmful Algal Blooms and the Global Ecology and Oceanography of Harmful Algal Blooms (GEOHAB). At a regional level, in 1992 he took over the leadership from Professor Okaichi on the HAB project of IOC/WESTPAC and served as the coordinator for nearly 20 years. He is also one of the focal points of Japan on the HAB Working Group of North Pacific Action Plan (NOWPAP))/UNEP and endeavoured to create a HAB network within PICES (North Pacific Marine Science Organization) and a HAB Project of IOC/WESTPAC.

There is no one in the harmful algal bloom research community who has not benefited greatly from his legendary generosity, beautifully presented images of algae and his pedagogy and public service sustained over three decades.
