List of countries & territories with coastline & reported seaplants

How big is the world seaplant market?
.... over 2 M tons worth 8 billion+ USDollars/annum

We are using market-size  estimates made by scientists. Good market statistics are essentially unavailable and scientists tend to be a conservative lot who only report numbers in which they have some confidence. Consequently most seaweed market are probably gross under estimates.

Indergaard & Jensen (1991) estimated that the mid 1980s.market for seaweed and seaweed gums could be summarized as follows:

Statistics concerning seaweed production volumes and values are hard to come by. SuriaLink hopes to serve as a vehicle for evolving increasingly accurate and timely figures.
