PROBLEM TO BE SOLVED: To provide a method for using a seaweed seeding yarn winder, for saving the labor of seeding yarn winding operation and efficiently using a seeding yarn in cultivation of seaweed such as kelp or brown seaweed.SOLUTION: A seaweed seeding yarn winder 1 is formed by winding a seaweed culture yarn around a hollow cylinder 3, and the seaweed seeding yarn winder 1 in which seaweed seeds are adhered to the yarn of the seaweed seeding yarn winder 1 and cultured for a prescribed period of time is used. A main rope is passed through a cylinder of the seaweed seeding yarn winder 1, one end of a seeding yarn 4 is connected to the main rope, and the main rope or the seaweed seeding yarn winder 1 is slid, whereby the seeding yarn 4 is automatically and spirally wound around the main rope. According to this, the winding operation of the seeding yarn 4 can be easily performed.COPYRIGHT: (C)2014,JPO&INPIT【課題】本発明は、コンブ、ワカメ等の海藻養殖の種糸巻き作業の省力化及び種糸の効率的利用を図るための海藻種糸巻付器の使用方法を提供する。【解決手段】中空の円筒体3に海藻養殖用の糸を巻き付けた海藻種糸巻付器1を形成し、この海藻種糸巻付器1の糸に海藻の種を付着させ、一定期間海藻の種を培養した海藻種糸巻付器1を用いて、前記海藻種糸巻付器1の筒内に幹縄を通し、種糸4の一端を幹縄に結び、幹縄又は海藻種糸巻付器1をスライドさせることにより、前記種糸4が前記幹縄に自動的に螺旋状に巻かれていく。このようにして、簡単に種糸4の巻き付け作業を行うことができる。【選択図】図1
