This seaweed does grow in the sea, obviously, however there isn't nearly enough of it in the sea to provide for the US (or worldwide, for that matter) cattle market.

Further, this particular seaweed is presently undomesticated – which means that of the various types of algal cultivation methods (rope culture, tumble culture, etc) no one has quite gotten down the best means of getting stable growth out of the strain. This is what we are working to do.
