術である。BACKGROUND OF THE INVENTION The present invention relates to a process in which an important key in rearing a seedling is to grow a willow leafy fry into a thin branch-like fry. It is a technology that can be applied to any coastal government that has the ability to grow seedlings for more than 6 days after hatching.

している。2. Description of the Related Art In artificial breeding, injection of gas for supplementing dissolved oxygen in water impacts on eel seedlings, which can be pushed up to the surface of the water, resulting in very fast nutrient depletion in the body. Nevertheless, it has no ability to absorb a large amount of nutrients from the outside, and significantly affects the metamorphosis of seeds and seedlings.
