PROBLEM TO BE SOLVED: To provide a method and an apparatus for relocating seaweeds each with excellent rootage by relocating without collapsing soil around roots which are collected together with seaweed while suppressing pollution of seawater.SOLUTION: This apparatus for relocating seaweed has a collecting case 1 which is attached to a relocation attachment 6, and composed of an outer case 2 whose front side is opened, and an inner case 3 whose front side inserted into the collecting case 1 and bottom are opened. The method for relocating seaweed comprises collecting seaweed W together with soil S around the roots from the front side through operating a back hoe boom 5, temporarily putting the collecting case 1 on a barge followed by transferring, making the collecting case 1 approach to the bottom of the sea through operating the back hoe boom 5, bringing the bottom of the inner case 3 fixed as it is in an opening condition through moving the outer case 2 back, and arranging the collected seaweed W together with the soil S in the bottom of the sea of relocation destination.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】移設アタッチメント6に取付けた回収ケース1を、前面を開口したアウターケース2と、アウターケース2に挿着した前面および底面を開口したインナーケース3とで構成し、この回収ケース1をバックホウのブーム5の操作により、その前面から海藻類Wを根本部分の土壌Sとともに回収し、台船に仮置きして移送した後、バックホウのブーム5の操作により、回収ケース1を海底に近づけ、アウターケース2を後退させて固定したままのインナーケース3の底面を開口状態にして、回収した海藻類Wを土壌Sとともに移設先の海底に配置する。【選択図】 図10
