ICHA 2021 Conference, NEW DATE!!


Due to the pandemic of COVID-19 and following the recommendations from the World Health Organization and National Health Authorities, we have postponed the 19th International Conference on Harmful Algae to the 10-15th of October, 2021. Also, in consideration of the traveling restrictions of the majority of the ISSHA community we have decided to hold this meeting in a 100% virtual format so that all the community can participate.


On behalf of the Organizing Committee, it is a pleasure to invite all the members of the international harmful algae science community to the 19th ICHA meeting that will be held for the second time in Latin America. The proposal of hosting the 19th ICHA in Mexico comes from our scientific members of the National Society for the Study of Harmful Algae Blooms (SOMEFAN, A.C.) and from the National Research Network of Harmful Algae Blooms (RedFAN-CONACyT). The SOMEFAN association has been hosting academic meetings every two years since 2011, and since 2015 RedFAN has supported many academic activities directed to increase our knowledge of HABs in Mexico. Both organizations include international scientists with whom we have initiated collaborations to attend the different problems our country encounters with Harmful Algae.


In our coasts, we have several harmful species that we share with other geographic regions Gymnodinium catenatum, Pyrodinium bahamense, Prorocentrum lima, Dinophysis spp, Pseudonitzschia spp, Cochlodinium polyrkikoides, Chattonella spp. and Microcystis spp., among others. Many of them have caused important impacts that have led to economic losses. During the last years, we have increased our monitoring capacities for the detection of these species and their toxins, but we still have many aspects to attend regarding harmful benthic species and harmful algae blooms in our fresh water systems, among many others. We are aware of the complexity of the impact of Harmful Algal worldwide and the importance to apply basic scientific knowledge to help resolve future challenges. For these reasons, our elected central theme for ICHA 2021 is from basic studies to future applications.


During this meeting international scientists and students will present their latest results on harmful algae from marine and freshwater systems covering a wide array of topics (taxonomy, genomics, toxins, ecology, life cycles, impacts, HAB technologies, surveillance, and management, among many others). Presentations types will include plenary lectures, oral presentations, speed talks, and posters. We are planning an enjoyable meeting where scientists can present their research, share their ideas, and establish new collaborations.


We look forward to welcome you in the 19th ICHA, and join us in a great virtual meeting!
