Abstract This study obtained hydroxyapatite (HA) material by extracting waste bones from rabbitfish ( Siganus sp.). The fish used are the of sp.); besides being readily available in nature, they also reduce unwanted environmental impacts. X-ray fluorescence (XRF) and scanning electron microscopy (SEM) observations were to analyze produced sintering process. Samples at temperatures 800 °C, 850 9...

The study aimed to determine the optimum dietary lysine level of orange-spotted rabbitfish Siganus guttatus Bloch, 1787 (average body weight range 5.2 7.6 gxfish-1). feeding trial was conducted for 8 weeks employing six experimental diets which were isonitrogenous, isocaloric, and isolipidic (35% crude protein (CP), 18.3 MJxkg-1 gross energy, 5% lipid). content ranged from 1.22 g 2.12 xkg-1 dry...
