PROBLEM TO BE SOLVED: To provide a cultivation method using a cultivation base material for seaweed belonging to Porphyra generating a thallus directly from a filament.SOLUTION: On a cultivation base material 1 used in a cultivation method for seaweed, projections 11 containing calcium carbonate as a main component, and formed by crushing coral or the like which is one of bones and fossils of a plurality of organisms by a prescribed size are fixed on a base 21 with a projection fixing material 31 which is a cement, an adhesive or the like. A free filament of seaweed belonging to Porphyra generating a thallus directly from a filament to the cultivation base material 1 is finely shredded by a mixer, and the shredded filament is sowed on top surface of the cultivation base material 1 in a water tank filled with sea water. The filament is perforated in each projection 11 to be raised for 1-10 months, and after then, the cultivation base material is installed on sand or rock land which becomes tideland during low tide.SELECTED DRAWING: Figure 1 |
