The effect of different levels of herbal supplement of Cumin powder (Cuminum cyminum) on growth, survival and carcass composition of the Litopenaeus vannamei was evaluated in the summer of 1395 for 56 days at the Persian Gulf Aquaculture reproduction and reconstruction center. For this purpose, four groups of shrimp with an average weight of 3.45±0.3 g in 300 liter fiberglass tanks with a density of 60 shrimp per tank, with different levels (0.5, 1 and 1.5 percent) was supplemented. The Cumin powder was fed with 3 replicates. At the end of the period, growth indices (average body weight gain, body weight gain, specific growth ratio and feed conversion ratio), survival rate, and chemical composition of these treatments were compared with control treatment. The results showed that the treatment with 1% Cumin powder had higher growth indices and better survival than other treatments (p<0.05). In the case of carcass biochemical analysis, the results showed a significant increase in protein and fat content and a significant decrease in moisture content in Cumin powder treatments compared to control (p <0.05). The results of this study showed that 1% Cumin powder in diet could be used to improve the growth performance, survival and quality of the carcass composition of white shrimp (Litopenaeus vannamei).
