A sixty days experiment was carried out to study the effect of feeding varying dietary protein diets on hematology of catla, Gibelion catla in biofloc system. The experiment consisted of four biofloc treatments with different dietary protein, T1 (20% CP), T2 (25% CP), T3 (30% CP) and T4 (35% CP) and clear water control without biofloc T0 (30% CP) each with four replicates. Catla fry of average weight (0.21±0.01g) were stocked at the rate of 3 fry per 10 L (24 no’s fish in 80L). C:N ratio 20:1 was maintained in biofloc system. Hematological parameters were analyzed before and after fingerlings were challenged with Aeromonas hydrophila pathogen containing 1 × 107 cfu/ml. The results revealed that 30% CP diet in biofloc system can improve the hematological profile of fish compared to control. During pre- challenge study, the dietary protein diet could not produce any significant difference (P>0.05) in RBC of catla fingerling compared to control. The WBC, Hb and Hct were significantly higher in biofloc treatments than control and increased with increase in protein level from 20 to 30% CP in biofloc treatment. During post- challenge RBC, Hb, Hct reduced and WBC count increased compared to pre- challenge. T3 group showed significantly (P<0.05) higher RBC, Hb and Hct and lower WBC compared to control. The result indicated that feeding 30% CP diet to catla fry in biofloc system could enhance the health condition as well as disease resistance of the fish and the technology can be considered useful for disease prevention in rearing practices of catla.
