Since 2019, he is a doctoral researcher at the Laboratory of Marine Environmental Sciences of the European Institute of the Sea, in Brittany, France. His doctoral research, supervised by Dr. Caroline Fabioux and Dr. Helene Hegaret, aims to decipher the main physiological and molecular mechanisms involved in contamination and decontamination kinetics by domoic acid in P. maximus, comparing its response with other fast-DA depurator species. Jose L. García-Corona Maureen Keller Awards to best student presentations Best student oral presentation José Luís García-Corona, from the European Institute for Marine Studies (Best, France) for his presentation about: In situ detection of the phycotoxin domoic acid in bivalve tissues: deciphering the subcellular mechanisms involved in its retention in the king scallop Pecten maximus coauthored by Caroline Fabioux, Hélène Hegaret, Elodie Fleury, Malwenn Lassudrie and Adeline Marzari. José Luis is a marine biologist graduated with honors from the Autonomous University of Baja California Sur in 2014. He received the State Youth Award and the Science and Technology Medal in 2017 for his contributions to science development in Mexico. He obtained a Master of Science degree in aquaculture biotechnology from the Biological Research Center of the Northwest in 2018, where he developed alternatives to improve gonad maturation and oocyte quality in marine bivalves with commercial interest in Mexico. His research is mainly focused on the study of the physiological, functional, and genomic responses of marine bivalves with highcommercial interest that face changing 12 Steffaney is also a 2018 graduate of Davidson College where she majored in Environmental Studies with a Chemistry minor. During her time at Davidson, she was awarded a NOAA Hollings Undergraduate Scholarship and had the opportunity to work in Dr. Vera Trainers lab. She credits this experience with fostering her interest in the ocean sciences and HAB research. Taichi Ataka Steffaney Wood Oral Presentation, Honorable Mention was awarded to Steffaney Wood, from Scripps University, La Jolla (USA) for her presentation on: Cyanobacterial akinete distribution, viability, and toxin records in sediment archives from the Northern Baltic Sea co-authored by Anke Kremp, Henna Savela, Sultana Akter, Vesa-Pekka Vartti5, Saija Saarni and Sanna Suikkane. Steffaney is a PhD student at Scripps Institution of Oceanography, UCSD in the Bradley Moore and Andrew Allen labs. She currently studies domoic acid biosynthesis in Pseudo-nitzschia diatoms. Steffany began her career as a Fulbright-EDUFI Fellow at the Finnish Environment Institute Marine Research Centre, conducting research on harmful cyanobacteria blooms in the northern Baltic Sea. She continued with the same topic her MSc in in Microbiology and Microbial Biotechnology at the University of Helsinki, Finland and completed it in May 2020. The work presented at ICHA2021 was part of that research. Taichi Ataka, Kochi University, Japan, received the Maureen Keller student award for the best poster titled, Effect of adding macroalgal extracts on the growth of Gambierdiscus scabrosus and G. silvae isolated from Japan, co-authored by Hiroshi Funaki, Haruo Yamaguchi, and Masao Adachi. Born in Japan, he pursued Bachelor of Agriculture and Marine Science at Kochi University and is pursuing his masters degree at Kochi University under the supervision of Prof. Masao Adachi. Koshi University is located in Shikoku Island, one of the warm-temperate areas in Japan where ciguatera poisoning (CP) has been sporadically reported. Taichi is very interested in clarifiying the mechanism of CP outbreaks in Japan including the clarification of the causative organisms and toxins for the poisonings in Japan. He is also interested in biological interactions in Gambierdiscus spp., in particular the interations between the macroalgae and Gambierdiscus and between Gambierdiscus and bacteria. He focused on the effect of fractions extracted from macroalgae on the growth of Gambierdisus in Japan and clarified that the addition of the extracts HARMFUL ALGAE NEWS NO. 69 / 20221 Harmful Algae News An IOC Newsletter on Toxic Algae and Algal Blooms No. 69 - February 2022 https://hab.ioc-unesco.org/ The 19th (1st Virtual) International Conference on Harmful Algae hosted from Mexico The 19th International Conference on Harmful Algae (19 ICHA), was held in a virtual format for Lobby of the virtual ICHA 2021 costs to attend the meeting.

We had five exciting and intensive virtual conference days where all the late predatorial protists, viruses, and bacteria (Alexandra Worden). Several plenary talks highlighted insights on HAB management, including emergent management strategies for monitoring, biotoxin detection, and human health risks associated with Ciguatera Poisoning (Marie-Yasmine Dechraoui Bottein); com Fig. 2.

A special session on the new WHO book Toxic cyanobacteria in water provided advice and guidelines for the management of freshwater cyanobacterial blooms, ISSHA's Corner The International Society for the Study of Harmful Algae (ISSHA) convened the 19th (1st Digital) International Conference on Harmful Algae (19 ICHA), held in La Paz, México, from 10th to 15th October 2021. The ISSHA Council had monthly meetings on-line between May and October to plan molecular probes targeting HAB species (including their different life cycle stages), difficult to identify with conventional microscopy methods.
