Abstract

In this study, the effects of three different culture techniques on larval development during larval period (0-35 day) in common dentex (Dentex dentex) which is accepted as a new candidate species in the recent years were investigated. Larval culture techniques which are circulated sea water, air-lift and closed systems were used. In circulated sea water system, sea water renewed during the day, and also renewed 10% per hour in closed system. Besides, in the air-lift system, sea water circulated inside of tank and 10% of volume renewed during the day. It is determined that the best total length development and weight was found as 20.45±4.3 mm and 86.22±6.3 mg in air-lift technique treated group. Also, these parameters were determined as 18.73±4.6 mm and 81.13±5.9 mg for closed system applied group and 16.96±5.2 mm and 71.34±7.4 mg for circulated sea water treated group. Although significant differences were found in circulated sea water treated group (p<0.05), there are no differences between air-lift and closed system treated groups (p>0.05) in total length development and weight. Also, swimbladder inflation rates were determined as 88%, 92 % and 89% for circulated sea water, air-lift and closed system treated groups respectively. Additionally, survival rates were calculated as 10.6±2.1%, 22.5±3.4% and 20.6±3.8% respectively. Similarly, differences between air-lift and closed system treated groups were not significant (p>0.05) whereas circulated sea water treated group was significantly different than the other groups (p<0.05).

Özet

Bu çalışmada, özellikle son yıllarda alternatif türler kapsamında değerlendirilen sinagrit (Dentex dentex) balığının larval döneminde (0–35 gün) 3 farklı üretim tekniğinin larval gelişime olan etkileri incelenmiştir. Çalışmada; akışkanlı su, air-lift ve kapalı devre üretim teknikleri kullanılmıştır. Akışkanlı su tekniğinde tanklardaki suyun 24 saat sürekli yenilenmesi sağlanmıştır. Air-lift yönteminde ortamdaki suyun her gün %10’u, kapalı devre yöntemde ise her saat %10’u yenilenmiştir. En iyi total boy 20.45±4.3 mm ve ağırlık 86.22±6.3 mg olarak air-lift üretim tekniğinin uygulandığı gruptan elde edilmiştir. Bu grubu 18.73±4.6 mm total boy ve 81.13±5.9 mg ağırlık değeri ile kapalı devre ve 16.96±5.2 mm total boy ve 71.34±7.4 mg ağırlık değeri ile akışkanlı su üretim tekniğinin uygulandığı gruplar izlemiştir. Total boy ve ağırlık gelişimi açısından, air-lift üretim sistemi ile kapalı devre üretim sistemi uygulanan gruplar arasındaki fark önemsiz bulunmuştur (p>0.05). Akışkanlı su üretim sistemi uygulanan grup ile diğer gruplar arasındaki fark ise önemlidir (p 0.05). Bunun yanında, yaşama oranları ise akışkanlı su, air-lift ve kapalı devre üretim sistemleri için sırasıyla %10.6±2.1, %22.5±3.4 ve %20.6±3.8 olarak saptanmıştır. Yaşama oranları bakımından akışkanlı su üretim sistemi uygulanan grup ise diğerlerinden farklıdır (p<0.05).
