In current study, the healthy osteological development of the vertebral column and of the caudal fin systems in sharpsnout seabream (Diplodus puntazzo) was described under intensive culture condition. In order to study the osteological development, it was used 610 specimens which were stained by Alsian blue for cartilage and Alizarin Red S for bone. The development of the axial skeleton began with the formation of the hypural I, the neural arches 1 and 4, as well as the haemal arches 1-6 at 4.3, 4.7 and 5.1 mm total length (TL, measured in vivo), respectively. The caudal lepidotrichia were the first membranous bones to appear (5.6 mm TL) and attain their full meristic counts (7.0 mm TL), followed by the vertebral centra, which formed between 5.9 and 8.4 mm TL. By 14.0 mm TL, all the elements were fully ossified except for the ventral ribs. The results of the skeletal ontogeny in D. puntazzo were compared with that reported for other Sparidae and Teleost fishes and also follow the same pattern of most Sparidae species investigated to date.
