Net material for submerged bivalve culture and its manufacturing method and submersible bivalve culture method

摘要

To provide a mesh material for aquaculture capable of being used in the ground-sowing system, the mesh material that can adjust a biodegradation speed in the sea, and provide its manufacturing method and an aquaculture method using the same.SOLUTION: A manufacturing method of a mesh material for submersible bivalve aquaculture comprises: a mesh fabric configuration step S102 of twisting natural fibers to configure a strand, and configuring a mesh fabric of a predetermined mesh size by the strand; a paraffin wax melting step S201 of melting a paraffin wax based on the paraffinic hydrocarbon; and a paraffin impregnation step S301 of immersing the mesh fabric configured by the mesh fabric configuration step S102 in the liquid melted by the paraffin wax melting step S201. The mesh material for submersible bivalve aquaculture is formed by coating at least a surface of the mesh fabric configured by the natural fibers with the coating material based on the paraffinic hydrocarbon. This is installed in the bottom of the sea as a planar-shaped or a bag-shaped aquaculture mesh.SELECTED DRAWING: Figure 1
