<P>PROBLEM TO BE SOLVED: To provide a method for rearing Carassius auratus grandoculis, environmentally friendly and improving a meat quality. <P>SOLUTION: This method for rearing Carassius auratus grandoculis includes rearing Carassius auratus grandoculis in a phosphorus deficiency condition by continuously administering for ≥50 days, phosphorus deficiency feed below a phosphorus requirement necessary for growing, with respect to phosphorus contained in the feed. It is desirable to bring the deficiency degree of phosphorus contained in the feed to 50-80% (both values are as effective phosphorus) of a phosphorus requirement in the rearing method. Furthermore, it is desirable to set after a deficiency rearing period for rearing in a phosphorus deficiency condition, a quasi-deficiency rearing period for administering quasi-deficiency feed below a phosphorus requirement and above a phosphorus dose in a deficiency rearing period, and rearing in a quasi-deficiency condition. <P>COPYRIGHT: (C)2011,JPO&INPIT |
