The broccoli plants (Brassica oleracea gemmifera L.) are full of organic and mineral matters and vitamins. The presence research was studied on the effect ofdifferent levels (0%, 0.2%, 0.5% and 1% respectively) of broccoli on hematological and biochemical parameters and growth of common carp (Cyprinous carpio). 300 fish (25 fish per tank with an average body weight of 2.11±0.24 g) were dieted for 8 weeks. The result showed that white blood cell count (WBC), total protein (TOP) and globulins (GLU) increased significantly in treatmeant group with 0.5% broccoli in comparison with the other groups (P<0.05). However, the amount of red blood cell count (RBC), hemoglobin (Hb), Hematocrit (Ht) and eosinophil in all the treatment groups increased than the control group with no significant difference (P>0.05). In relative of growth indices, the amount of Protein Efficiency Ratio (PER), Body Weight Index (BWI), Food Efficiency (FE) and Growth Rate (GR) between treatment groups were increased in comparison with the control group but, not significantly (P>0.05), but the amount of Specific Growth Rate (SGR) at the treatment with 0.2 percent in comparison with the control group showed the significant difference (p<0.05). In the end, we can conclude that it seems that 0.5% of broccoli in the diet can have a better effecton hematological, biochemical parameters and growth indices and increase the growth, immune system and health of the fish.
