Organizers of the 8th International Symposium on Aquatic Animal Health have opened registrations and called for abstract submissions for oral and poster presentations. The 2018 symposium marks the thirtieth anniversary of the ISAAH, which will be held September 2 – 6, 2018 in Prince Edward Island, Canada. Early Bird registration rates are available now, and, as there are limited spaces for registered delegates to attend the pre-conference scientific workshops, organizers encourage participants to sign up as soon as possible.
