PROBLEM TO BE SOLVED: To efficiently and labor-savingly cut and collect a large amount of laver attached to a culture net from the root portion of the lever in a natural standing state differently from a conventional laver-collecting method broadcasted on television. SOLUTION: A long drum 1, a laver-culturing net and a net-receiving plate 14 are pressed up by the flotation force of a float 15. Fast water flows are produced between the drum and the net-receiving plate with mutually faced two pumps 81 , 82 disposed in the drum. The approximately vertically stood laver in a laver-sucking groove opening 23 is cut from its root portion with a cutter 7, and subsequently sucked together with sea water into a net-attached curved pipe 13 disposed at the center of the drum. The sucked laver is filtered with a laver-receiving net bag and subsequently taken out by reciprocating works wherein the net bag is wound and drawn with a winch between a land and a slip on the opposite side of the culture net. |
