Bu çalışmada nil tilapiaları ve onların melezlerinde (Oreochromis niloticus dişi x Oreochromis aureus erkek) ilk stok ağırlığının ve boylamanın büyümeye ve yem değerlendirmeye olan etkileri araştırılmış ve farklı boy kompozisyonları ile stoklamaya başlanarak ve hangi boyda stoklamanın hangi grupta daha verimli olduğu konusunda bir fikir oluşturulmuştur. Çalışmanın bir diğer boyutunda ise farklı ağırlıklara sahip bireyler karışık olarak yetiştirildiklerinde yalnız küçük ya da sadece büyük boyda yetiştirilenlere oranla ne ölçüde bu durumdan etkilenecekleri araştırılmıştır. Denemede küçük melez yavruların büyüklere oranla daha iyi büyüdüğü, kışlatılmış gruplarda hem nil tilapialarında hem de melezlerde karışık grupların daha iyi büyüme ve yem değerlendirme oranlarına ulaştığı saptanmıştır.

Effect of First Stocking Size on Growth Performance and Feed Intake of Tilapia Hybridization

Öz

In this study, effects of first stocking size and size grading on growth of nile tilapia and their hybrids (Oreochromis niloticus female x Oreochromis aureus male) were investigated. A decision has been made on which stocking system has been more effective on which size grading of stocking, starting the stocking with different size grading compositions. In another dimension of the study; it's been researched that in what amount would this situation effects when individual with variable weights are placed randomly compared to placements with either only small or large. At the end of the research hybrids were higher growth value than nile tilapia. Furthermore, mixed groups either hybrids, or nile tilapia groups were made better growth rate and FCR than the other groups (graded groups).
