Özet
In this study, skeletal deformities were investigated during early life stages according to notochord flexion in European sea bass ( Dicentrarchus labrax ) larvae under intensive culture conditions. In order to detect the skeletal deformities, total 836 larvae were stained by Alcian blue and Alizarin Red S. Total length of Newly hatched larvae length were 3.46±0.02 mm and end of the study it was 18.58±0.1 mm. Totally, 836 specimens were examined during the experiment but 1256 deformities were recorded in 270 deformed larvae. Also, skeletal deformity rate was calculated as 32% at the end of the study. Most viewed skeletal deformities were recorded as vertebral malformations (21.3%) and followed by vertebral fusion (18.6%) and lordosis (12.7). The highest amount of skeletal deformity was determined after notochord flexion stage (52.1%) in the study.
