A process for producing a biocompatible material includes the steps of mixing an extract of a fish scale-derived hydroxyapatite (with water content of 70 to 75% by weight) and of a fish scale-derived collagen (with water content of 40 to 60% by weight) in the weight percent ratio of about 8:2, stirring the mixture and drying the mixture by a hot blast in order to obtain a composite.
