The 24^th ISS committee has chosen the theme ‘Seaweeds in a changing world’, to focus on ongoing changes in seaweed aquaculture practices, industrial processing, future products and markets, local and global environmental change, and scientific advances that will change our understanding of how seaweeds function at all levels of organisation.

The symposium format will enable actual and virtual delegates and presenters to attend and interact, and we expect a vibrant and exciting new style of conference.  The organising committee feels the opportunity to have the Symposium also hosted online presents an opportunity for us to reach a broader audience than the traditional Symposium. As such, we see 2023 as being a new and positive direction for the Symposium.
