Exploitation
The sea lettuce is harvested by the company BioMolenez. It is found in well-lit deep waters. It is therefore often submerged and only appears at high tide.
It can be harvested throughout the year, but preferably in spring and autumn at mid-tide. Once harvested, the seaweed is macerated and filtered to obtain an extract containing a maximum of bioactive compounds.
Mainly found in the coastal waters of the North Atlantic, the Mediterranean Sea, and the Black Sea. It is often found in areas exposed to waves and strong currents. It is also found in tropical and temperate waters of the Indo-Pacific.
Temperature tolerance: 0 to 30
