Abstract

In this study, in order to investigate the effect of Caraway (Carum carvi) on growth parameters and body approximate composition of Huso huso (Linnaeus; 1758) fingerlings, 3 diet containing 10%, 15% and 20% of Caraway with control diet that had not Caraway in its composition was utilized for feeding the Huso huso  fingerlings. Fishes with initial mean weight of 10 g were fed with control diets in 7 weeks and growth parameters including total length, total weight, protein efficiency ratio, feed conversation rate and body approximate compositions were measured and analyzed. Results showed that the diet with 15% Caraway has the best effect on growth parameters of Huso huso fingerlings and lead to more gaining weight (146.60±1.85 g) than other diets. Moreover, between body approximate compositions, only the protein and moisture level were affected by diets containing Caraway. Maximum protein was observed in fingerlings fed with diets containing 10% and 20% Caraway. According to obtained results, using the diet with 15% Caraway recommend in order to enhance growth of Huso huso fingerlings.
