Özet

In this study, skeletal deformities were investigated during early life stages in sharpsnout seabream, Diplodus puntazzo, larvae during larval development period. Whole larval period (1-42 days after hatching, DAH) was examined in three stages (preflexion, flexion and postflexion) based on notochord curve. Totally, 1210 specimens were examined during the experiment but 689 deformities were recorded in 256 larvae. Also, deformity rate was calculated as 21.2% at the end of the experiment. In terms of notochord flexion at stage-specific, no differences were found between preflexion (19.7%) and postflexion (15.8%) stages (p>0.05) while there was a significant difference during flexion stage (32.8%) in comparison with other groups (p<0.05). Correspondence analysis (CA) was performed in order to describe of skeletal deformities mainly depend on notochord flexion. According to CA analysis, it was determined that deformities were closely related with both flexion stages quantitatively and also postflexion stages qualitatively.
