Özet
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three diets were prepared: Control diet (FM); without T. molitor larvae meal, insect diet (TM); 100% of fish meal has been replaced by T. molitor larvae meal and mixture diet (FM/TM); 50% of FM has been replaced by T. molitor larvae meal.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.
