Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a tasteless/odorless gelatin and/or a collagen peptide derived from fish scale and having relatively low number-average molecular weight, usable for foods, health foods, cosmetics, etc., and having excellent cost performance. SOLUTION: The method for the production of a collagen peptide comprises the pretreatment of an acid-decalcified wet crude collagen with a strongly basic diluted solution in a process to produce a collagen peptide by the hydrolysis of a crude collagen obtained by the acid decalcification of fish scale or a process to produce a collagen peptide by extracting gelatin from a crude collagen obtained by the acid decalcification of fish scale and hydrolyzing the gelatin. As an alternative, the method for the production of a collagen peptide comprises the pretreatment of an acid-decalcified wet crude collagen with a strongly basic diluted solution in a process to extract gelatin from a crude collagen obtained by the acid decalcification of fish scale.
