  • Valorization of fisheries by-products Challenges and

     · Various fish species have been used for the extraction of fish bone powder and its nutritional qualities have been determined. Fish bone powder is high in calcium (234 g/kg dry bone) mainly in the form of hydroxyapatite (HA) and calcium carbonate (Kang Heu Kim 2006). Fish bones in the form of fish frames (often with adhering meat) are available in two forms cooked and uncooked.
