Pelagic Sargasso nowadays is an inopportune event that invades beaches. This method has many aspects in consideration to successfully grow Sargasso in huge amounts in a designated area. It also discloses many Sargasso Nursery Structures that adapt to different areas and purposes. This method also discloses where and how to set the nurseries in a way that the Sargasso mass can be used or delivered avoiding heavy costs of shipping.
