METHOD FOR PROMOTING FEMINIZATION OF EEL WITH FEED COMPOSITE AND LIGHT SOURCE

摘要

The present invention relates to a feed suitable for the transformation period of a freshwater eel so as to promote magnetization and to be applied to a naturalization target of a second transformation period in the process of growing from a fish to a sea urchin of freshwater eel And a method of inducing magnetization According to a preferred embodiment of the present invention, a feed containing isoflavone or estrogen and a feed excluding the magnetization inducing substance as a magnetization inducing substance for the culturing target word (self-targeting target word) are fed alternately at regular intervals The feeding period of the light source from the light source is also changed according to the feeding period of the feed containing the magnetization inducing substance and the feed not containing the magnetization inducing substance to induce stable induction of the magnetization in the transformation period of the freshwater eel .
