PROBLEM TO BE SOLVED: To provide a method for transplanting seaweed by which soil at the root parts of the seaweed collected together with the seaweed is transferred without being crumbled while preventing seawater from contamination to improve rootage of the seaweed: and to provide a device for transplanting seaweed.SOLUTION: The method for transplanting seaweed comprises the following process: pressing a cylindrical collection case 1 onto seabed soil S from above using a press-fitting attachment 5 attached to the tip end part of a boom 4 of a back hoe 3 followed by mounting a bottom plate on the bottom part of the collecting case 1 using a slide attachment changed for the press-fitting attachment 5 to close the bottom part housing the seaweed W in the collecting case 1 together with the soil S temporarily placing the collecting case 1 on a barge 7 to be moved setting the collecting case 1 on the soil for transplanting the seaweed followed by eliminating the bottom plate using the slide attachment placing the seaweed W on the soil for transplanting the seaweed together with the soil S and then raising the collection case 1.COPYRIGHT: (C)2007,JPO&INPIT【課題】海水の汚濁を抑えつつ、海藻類と一緒に回収した根本部分の土壌を崩すことなく移設して、海藻類の根付きを良好にする海藻類の移設方法および移設装置を提供する。【解決手段】上部および底部を開口した筒状の回収ケース1を、バックホウ3のブーム4の先端部に取り付けた圧入アタッチメント5を用いて、海底の土壌Sに上方から圧入した後、圧入アタッチメント5から付け替えたスライドアタッチメントを用いて、回収ケース1の底部に底板を装着して閉口し、回収ケース1の内部に海藻類Wを土壌Sとともに収容し、この回収ケース1を台船7上に仮置きして移動し、移設先の土壌に回収ケース1を設置後、スライドアタッチメントを用いて底板を除去して、海藻類Wを土壌Sとともに、その土壌に配置してから回収ケース1を引き揚げる【選択図】図1
