A variety of ecology studies are important to add in the construction of Gracilaria seaweed farms on the Caribbean coast of Panama. ln the coast line of the district of Colon; Panama. five species of Gracilaria are currently recognized by Mark Hay and James Norris. This study presents the commercial feasibility of seaweed farms planted into a largoon using protected semi-protected and unprotected systems of culture. The results of the experiment showed that heat grazing has a significant impact on Gracilaria production. But fishermen must consider the cost of establishing and maintaining the protected structure in the culture.
