Özet

This study investigated the effects of dietary supplementation with different levels of tea flower (Camellia sinensis) powder on body indices of juvenile koi carp (Cyprinus carpio). Fish were fed diets containing 0, 5, 10, and 20 g/kg tea flower powder for 90 days. According to the results, statistically significant differences were observed among the groups in terms of length and weight values. The highest values were recorded in the control group, while the lowest values were found in the 20% TFP group. The viscerosomatic index (VSI) reached its highest value in the 10% TFP group, whereas a significant decrease was observed in the 20% TFP group (P<0.01). In terms of flesh yield and condition factor, no significant difference was found between the control and 5% TFP groups, while significant differences were detected compared to the other groups (P<0.01). Significant differences were also observed among the groups for hepatosomatic index (HSI) and gonadosomatic index (GSI) (P<0.01); an increase was noted in the 5% TFP group, while a marked decrease was observed in the 20% TFP group. In conclusion, tea flower powder showed positive effects on growth and somatic parameters at low inclusion levels, whereas this effect decreased at higher levels. Its use at appropriate rates may be considered a functional feed additive in koi carp production. However, more comprehensive studies are needed in the future to elucidate the mechanisms of action.
