PROBLEM TO BE SOLVED: To provide a raw material of mixed feed for fish breeding using a vegetable raw material containing fibers in which a fiber content is reduced so that quite carnivorous fishes can easily digest, wherein the CP content is improved than a vegetable raw material; and to provide a production method thereof.SOLUTION: A raw material of mixed feed for fish breeding is produced by fermenting a vegetable raw material containing fibers with a non-selective white-rot fungus that has been considered to have low utility value in the study of lignin degradation technique, wherein lignin is degraded and at the same time cellulose, hemicellulose, and the like are also non-selectively degraded. Thereby, the raw material of mixed feed for fish breeding becomes the raw material in which lignin derived from vegetable raw material is not only degraded but cellulose and hemicellulose are also degraded, resulting in advanced glycation in which the fiber content is reduced so that quite carnivorous fishes can easily digest.SELECTED DRAWING: None |
