Hydroxyapatite (HA) is a calcium phosphate bioreactive and biocompatible material which is an essential element for bone regeneration in human and animal bodies. HA can be found abundant in bones and shells of aquatic animals. The extraction or recovery of HA from aquatic species play an important role in future biomedical applications such as drug delivery, implant coatings, scaffolds for bone grafts, etc. [1]. Therefore, in our study, a wet chemical method was utilized for extraction of HA from bones of different types of seafood wastes (Oreochromis spp, Channa striata, Thunnus albacares, Notopterus notopterus, Salmo salar, Pangasius krempfi). The extracted HA powders were characterized by different characterization methods such as FTIR, XRD, Optical microscope and ICP-MS. Their bioactivity was also evaluated by the immersion of HA powders in stimulated body fluids. The results showed that the extracted HA powders from bones of Channa striata species had the best biocompability and be a good candidate material for bone regeneration, particularly when they existed at a nano-scaled size.
