Abstract

In the study, isoleucine-enriched artemia (test groups) and non-enriched artemia (control group) were used in the first feding of African catfish (Clarias gariepinus) larvae. Test groups consisted of Isoleucine (Isol)-3, Isol-5, Isol-7 and Isol-14 groups, while control groups consisted of Cont-3, Cont-5, Cont-7 and Cont-14 groups. Fish larvae weaned to dry feed on the 3rd, 5th, and 7 th days for the Isol-3 and Cont-3, Isol-5 and Cont-5, Isol-7 and Cont-7 groups respectively and after that time feeding was continued with the dry feed until the end of the study. In Isol-14 and Cont-14 groups, only live feed was given to fish larvae for 14 days. At the end of the study, the effects of weaning days on the growth performances of African catfish larvae and the relationships between length and weight were evaluated. The highest weight averages was measured in the Cont-5 (25.41 mg) group, and the lowest in the Isol-14 (4.52 mg) group (P 0.05). The best development in terms of specific growth (SGR) and live weight gain (LWG) was observed in Kont-5 and İzol-3 groups. The lowest survival rate was 44.76% in Isol-7 and Isol-14 groups. In conclusion, the best developmental performances of the study were observed in Isol-3, Cont-3, and Cont-5 groups. In addition, it was also concluded that, long-term feeding with isoleucine-enriched artemia slowed down development in African catfish larvae.

Özet

Araştırmada, karabalık (Clarias gariepinus) larvalarının ilk beslenmesinde, izolösin ile zenginleştirilmiş artemia (test grubu) ve zenginleştirilmemiş artemia (kontrol grubu) kullanılmıştır. Test grupları, İzolösin (İzol)-3, İzol-5, İzol-7 ve İzol-14 gruplarından, kontrol grupları ise Kont-3, Kont-5, Kont-7 ve Kont-14 gruplarından oluşmuştur. İzol-3 ve Kont-3 gruplarında 3. gün, İzol-5 ve Kont-5 gruplarında 5. gün, İzol-7 ve Kont-7 gruplarında ise 7. gün toz yeme geçilmiş ve çalışmanın sonuna kadar toz yemle besleme yapılmıştır. İzol-14 ve Kont-14 gruplarında ise 14 gün sadece canlı yem beslemesi yapılmıştır. Çalışmanın sonunda, canlı yemlerin ve toz yeme geçiş günlerinin karabalık larvalarının büyüme performansları üzerine etkileri ve boy-ağırlık arasındaki ilişkileri değerlendirilmiştir. En yüksek ağırlık ortalamaları Kont-5 (25.41 mg) grubunda, en düşük ise İzol-14 (4.52 mg) grubunda ölçülmüştür (P 0,05). Spesifik büyüme (SBO) ve canlı ağırlık kazancı (CAK) bakımından en iyi gelişme Kont-5 ve İzol-3 gruplarında gözlenmiştir. En düşük yaşama oranları (YO) İzol-7 ve İzol-14 gruplarında %44.76 olarak gerçekleşmiştir. Sonuç olarak; en iyi gelişim performansları İzol-3, Kont-3, ve Kont-5. gruplarında gözlenmiştir. Ayrıca, izolösince zenginleştirilmiş artemia ile uzun süreli beslemenin karabalık larvalarında gelişmeyi yavaşlattığı belirlenmiştir.
