Upcoming conferences


The next International Conference on Harmful Algae will take place October 21-26 2018 in Nantes, France. Registration will open during 2017. ISSHA members can register at special rates!

The 18th International Conference on Harmful Algae will take place from 21 – 26 October 2018 in Nantes, France. It is the second ICHA in France. As the last two conferences, a major goal of the 2018 conference is to connect the science on harmful algae with the beneficiaries of this research. The scientific program will range from Harmful Algae Biology and Toxins over Surveillance and Management of Harmful Algal Blooms to their impact on the socio-ecosystem.


Nantes is the regional capital of the “Loire Departments” on the French Atlantic coast (inner Bay of Biscay). The area is known as a major producer of cultured oysters and mussels in the country. It is also a secure and beautiful city, where tourists and business visitors can relax and enjoy themselves. The climate in the Atlantic area of France is temperate, in October temperatures are expected to range between 10 and 20 ºC.

For some countries visa may be required. Please check visa regulations well in advance (the process may take several months) with your local French Consulate for official instructions on the specific visa regulations and application procedures.

As the major host of the conference, ISSHA will support the event with various activities: Travel awards to students and post-docs (link), ISSHA auction (link), and several achievement awards (links).

Looking forward to seeing you in France !
