Seaweeds in a changing world
24th International Seaweed Symposium19 - 24 February 2023

The 24th International Seaweed Symposium will be held for the first time in Australia.  It will take place in Hobart, Tasmania, Australia’s most southern state, from Sunday 19th to Friday 24th February 2023.

On behalf of the International Seaweed Association (ISA) and the Local Organising Committee (LOC), we would like to inform you that we have made the difficult decision to postpone the 24th ISS for one year.  The new dates are: 19 – 24 February 2023.

We plan to retain a hybrid structure, but hope the majority of delegates and invited speakers will travel to Hobart. The ISS themes and sessions will remain the same and the invited speakers have been retained for 2023.

We very much look forward to seeing you in Hobart in 2023.

On behalf of the LOC,
Prof. Catriona Hurd and Prof. Michael A. Borowitzka

24th International Seaweed Symposium Co-Chairs

Hobart is a vibrant city, located at the foothill of kunanyi/Mt Wellington and situated along the Derwent River. It offers a contrasting blend of heritage (being Australia’s second oldest capital), scenery and culture. With its captivating history, picturesque waterways, rugged mountains and gourmet experiences, the city has something for everyone.

Australia has a proud tradition of phycological research with a very diverse algal flora. Tasmania is a global hotspot for seaweed diversity with >750 named species with many endemic species. In Tasmania we have a flourishing bioactives industry and rapidly developing aquaculture industries, including Integrated Multi-Trophic Aquaculture and Asparagopsis culture. We also have a strong tradition in research on seaweed ecology and physiology, focused on climate change and mitigation. Tasmania is also the gateway to the spectacular and diverse algal flora of mainland Australia. We are excited to welcome you to the 24th ISS.

The 24th 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.

We have changed the symposium format to embrace new technologies that allow actual and virtual delegates 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 2022 as being a new and positive direction for the Symposium.
