On behalf of the official organizing committee, the International Association of Astacology, and the hosting institution, the Faculty of Fisheries and Protection of Waters, University of South Bohemia, as well as the Organizing and Scientific committee, I would hereby like to cordially invite you and update some information to the postponed IAA 23 Symposium It will take place in the beautiful South Bohemia Region of the Czech Republic from June 20 to 25, 2022. All registrations made since 2019 are still valid and should be paid till March 31, 2022. Because of the strange Covid19 situation, we decided to offer also online attendance with all its pros and cons.

Important information related to the Covid19 situation:

• Refund for registration without cancellation fee until April 30 and 50% until the end of May 2022.
• Online access will also be allowed when you register correctly and do not come for unexpected reasons (etc., guarantee). We will return the difference from the registration, including trips and official dinner (not accommodation and transport – this is under your control).
• Suppose the government bans on-site conferences (we do not expect that, given that the Covid19 situation is typically calm here in the summertime), the entire conference will be switched to online. The difference in the conference fees will be fully refunded.
