摘要

The influences of three different light intensities were investigated on growth of common dentex (Dentex dentex) during larval period (0-35 day). Three different illumination levels were compared that 10 lx as group A, 30 lx described group B and 100 lx named group C in triplicates, respectively. Larvae were cultured in a recirculating aquaculture system using a green water technique. The longest total length and the heaviest weight were found as 18.43+or-1.9 mm and 38.48+or-5.1 mg in group B with 30 lx light intensity. Same parameters were 18.03+or-2.5 mm and 36.72+or-4.8 mg for group C with 100 lx light intensity; 16.23+or-1.7 mm and 28.53+or-4.2 mg for group A with 10 lx light intensity. In terms of total length and weight, there were significant differences in group A (P<0.05), however, differences were not detected between B and C groups (P>0.05). Also, swim bladder inflation rates were calculated as 88.3+or-2.7, 92.1+or-1.6 and 91.4+or-1.3% for groups A, B and C, respectively and did not presented significant differences among groups (P>0.05). In addition, survival rates were 8.8+or-3.1, 23.5+or-2.5 and 19.9+or-2.8%, respectively. While not significant differences were found between group B and C (P>0.05), but group A presented significantly difference compared to other groups (P<0.05). As a result, it is thought that illumination effected husbandry parameters were more affirmative with 30 lx light intensity in Dentex dentex under culture conditions.
