Abstract

The aim of this study was to evaluate the effects of feeding Nile tilapia juvenile (Oreochromis niloticus) with diets based on fish meal (FM) and Tenebrio molitor (TM) larvae meal on growth performance and feed efficiency. For this purpose, three diets were prepared: Control diet (FM); without T. molitor larvae meal, insect diet (TM); 100% of fish meal has been replaced by T. molitor larvae meal and mixture diet (FM/TM); 50% of FM has been replaced by T. molitor larvae meal. Each treatment was tested in three replications over a 46-day. In the experiment, 1-month-old Nile tilapia juveniles with an average weight of 0.12±0.001 g were used. At the end of the experiment, the best growth was in the FM group, followed by the TM group and FM/TM group, the differences being significant except for FM and TM groups (P<0.05). Weight gain was also in line with growth rates. The SGR was 5.35%, 5.27% and 5.21% in FM, TM and FM/TM groups, respectively, and The difference between FM and FM/TM groups was statistically significant (P<0.05). The best FCR was in the FM group which was similar to TM diet (P<0.05). The worst FCR was in the group fed FM/TM diet with a significant difference from the other treatments. The PER changed between 0.87±0.07 and 1.42±0.04 with significant differences among the treatments. The survival rate was 100% in all groups. The data obtained showed that TM has the potential to be used as a protein source in diets of juvenile tilapia.

Özet

Bu çalışmanın amacı, Nil tilapiya yavrularının (Oreochromis niloticus) balık unu (FM) ve Tenebrio molitor (TM) larva unu bazlı diyetlerle beslenmesinin büyüme performansı ve yem verimliliği üzerindeki etkilerini değerlendirmektir. Bu amaçla üç diyet hazırlanmıştır: Kontrol diyeti (FM); T. molitor larva unu içermeyen, böcek diyeti (TM); balık ununun %100'ü T. molitor larva unu ile değiştirilmiş ve karışım diyeti (FM/TM); FM'nin %50'si T. molitor larva unu ile değiştirilmiştir. Deneme 46 gün boyunca üç tekrarlı olarak test edilmiştir. Denemede, ortalama ağırlığı 0.12±0,001 g olan 1 aylık Nil tilapiya yavruları kullanılmıştır. Deneyin sonunda, en iyi büyüme FM grubunda gerçekleşmiş, bunu TM grubu ve FM/TM grubu izlemiş, FM ve TM grupları dışındaki farklar önemli bulunmuştur (P<0.05). Ağırlık artışı da büyüme oranlarıyla uyumluydu. SGR değerleri uygulamalar arasında karşılaştırılabilirdi (P>0.05). SGR, FM, TM ve FM/TM gruplarında sırasıyla %5.35, %5.27 ve %5.21, ve FM ile FM/TM grupları arasındaki fark istatistiksel olarak önemli bulunmuştur (P<0,05). En iyi FCR, TM diyetine benzer olan FM grubunda tespit edilmiştir (P<0.05). En kötü FCR, diğer uygulamalardan önemli bir farkla FM/TM diyetiyle beslenen grupta görülmüştür. PER 0.87±0.07 ile 1.42±0.04 arasında değişmiş ve uygulamalar arasında önemli farklılıklar görülmüştür. Tüm gruplarda yaşama oranı %100 olmuştur. Elde edilen veriler, TM'nin protein kaynağı olarak kullanılma potansiyeline sahip olduğunu göstermiştir.
