The present research aims to evaluate the impact of both dietary vitamin E and dietary sage supplementation on growth performance of koi carp fingerlings, reared in a partial recirculating aquaculture system. Koi carp specimens with an average individual biomass of 5.1 ± 0.4 g were equally distributed, as follows: V1 - diet supplemented with 1% vitamin E (V1), respectively, V2 - diet supplemented with 1% sage. A 5% BW (Body weight) daily feeding ratio was applied. During the 49 days trial, individual biomass measurements were performed at initial, after 8, 15, 25 and 37 days, as well as at the final stage of the experiment. The specific growth rate indicates a superior fish production at V2 (3.30%BW/day), compared to V1 (2.75%BW/day). Also, better FCR values are recorded at V2 (1.28), compared to V1 (1.62). The Protein efficiency ratio (PER) results indicate a better ability of V2 koi carp specimens to utilize proteins (1.39), compared to V1 specimens (1.10). Thus, dietary supplementation with 1% sage has a superior effect on growth performance of koi carp fingerlings, compared to 1% vitamin E dietary supplementation.
