Özet
In this study, morphological development and allometric growth were investigated in the sharpsnout seabream, Diplodus puntazzo, during larval development until the end of the weaning on day 42.Average total length (TL) of newly hatched larvae was 2.91±0.11mm and it was 3.35±0.13mm TL at the onset of feeding at 4 days after hatching (DAH).Initial swimbladder inflation occurred at 10 DAH (5.11±0.45mm TL) and post-inflation became more elongate at 15 DAH (5.95±0.43mm TL).The notochord flexion occurred between 5.95±0.43mm TL at 15 DAH and 7.98±0.72mm TL on 24 DAH.At the end of weaning, larvae were 16.03±1.74mm TL at 42 DAH.The majority of all allometric changes from inflection point were integrated with the larval and the metamorphosis stage.Inflections in body proportion changes occurred mainly at 5.12, 5.95 and 7.98 mm TL, corresponding to initial swimbladder inflation and flexion period of notochord, respectively.
