This study was conducted to estimate the yield percentage of calcium (Ca 2+ ) in catfish
(Clarias gariepinus) bones. They were treated by alkaline treatment. The treated fish
bones were milled for easy handling. The fish bone powder is small particle size, grey
colour with a little fish odour. The bones were analyzed for proximate composition
according to AOAC method. The samples also was analyzed by using Atomic
Absorption Spectrometer (AAS) to determine the calcium content. Calcium
bioavailability of fish bone powder was compared with other calcium sources. Catfish
bones extract powder could be a good alternative of calcium fortificant and also could
improve the amount of calcium intake among people and in particular for those who
has lactose indigestion and intolerance.
