Production
Laminaria is the most abundantly produced of all macrophytic algae. Approximate annual production figures from recent years are as above.
Biology & Agronomy
Laminaria is extensively farmed in China, Korea and Japan. It is also harvested from wild stands in Northeastern North America, Iceland, Greenland and Western Europe. There is a great deal of material published on Laminaria in various languages and SuriaLink is in the process of organising and linking this material.
Chemistry
SuriaLink has a monograph in preparation on the chemistry of alginates.
Processing
We have several monographs in progress covering analytical procedures post-harvest treatment and process technology. Check the processing index for available web pages and monographs. 
Products, Uses & Applications
Laminaria has many applications and is the most extensively utilised of all seaplant genera.
