The Breton coast stretches on 1.800 km, is near a third(third party) of the French coasts and supplies about 90 % of seaweeds harvested in France.
The maritime environment is here an excellent domain and the valuation of the navy resources a tradition.
Thalassotherapy, amendment of soils, feeds, dietary nutrition, so many domains of use of the seaweeds which date here the last century.
