Abstract Natural immunostimulants and growth‐promoting functions of medicinal plants in aquaculture have been on a steady rise. The present study was carried out to understand the effect of dietary peppermint ( Mentha piperita ) on growth, survival, disease resistance and haematology of Labeo rohita . Diets incorporating M . piperita at 0.5%, 1%, 1.5% and 2% kg/feed were used as test diets with diets lacking peppermint as the control. The results revealed that peppermint‐incorporated diets showed better growth performance of fishes. Growth parameters were recorded significantly ( p < 0.05) higher in fishes fed with 2% peppermint. Haematological parameters such as erythrocytes, leucocytes and haemoglobin counts were enhanced in all the treatments with significant increase ( p < 0.05) observed in fish fed with 2% peppermint. Biochemical profiles such as total serum protein were also significantly higher in the peppermint diet‐fed fishes compared to control group. However, serum cholesterol, serum glucose and serum magnesium were significantly lower in treatment than control. Dietary incorporation of peppermint in all concentrations stimulated the immune system and increased resistance against Aeromonas hydrophila infection. However, the present investigation showed that the peppermint may be incorporated up to 2% per kg feed for better growth, survival and disease resistance of rohu fingerlings.
