About isa SEAweed

The International Seaweed Association (ISA) welcomes you to its web site. The ISA is an international organisation dedicated to the encouragement of research and development of seaweed and seaweed products.

One of the main activities of the ISA is the organisation of a 3-yearly International Seaweed Symposium of which 23 have now taken place all over the world. The 23rd Symposium took place in Jeju, South Korea in 2019 and the next will be in Hobart, Tasmania 2022.

The Proceedings of Symposia are published on behalf of the ISA under the general title of “Proceedings of the International Seaweed Symposium”. More recently, selected papers presented at symposia are published by the Journal of Applied Phycology

Mission & Vision

The mission of the ISA is to promote applied phycology on a global basis, and to stimulate interactions among research workers and industrialists in all relevant institutions and industries in all countries. Within this mission, the objectives of the ISA are primarily directed towards seaweeds, but also include other algae including cyanobacteria, as well as algal constituents.
