Description of the Related Art Generally, in the culture of seaweeds such as wakame seaweed, spores are first attached to seed threads (natural palm threads) using a bud strain, and then cultivated indoors by immersing them in a tank containing seawater. It is carried out in two stages: an indoor culture step of performing the indoor culture step and an underwater aquaculture step of growing the material grown in the indoor culture step in the sea. In indoor culture, spores germinated after a while and grew into gametophyte of male and female, and fertilized in autumn after the high temperature period of summer, and from October to November, from seed thread to leaf length 1-2.
cm seaweed sprouts. Next, at this stage, the undersea aquaculture is carried out by winding a seed yarn around a large aquaculture rope, attaching a blowing ball and fixing it to an undersea aquaculture facility.

るものである。At present, the commercial value of wakame seaweed depends on its morphology, leaf body (leaf quality, leaf thickness),
It is determined by yield and harvest time. The wakame cultivated in the production area A on the Sanriku coast, which is the main production area of wakame, has good leaf bodies, but it grows slowly and the product yield is poor.
On the other hand, wakame seaweed from the production area B other than the production area A has a poor leaf body, but grows quickly, and the product yield is good. Thus, the traits of wakame seaweed, which determine the commercial value, differ depending on the place of origin, and no wakame seaweed with all the conditions has been produced so far. The present invention solves such conventional problems and provides a method for growing seaweed having various conditions of high commercial value.
