The aim of the present study was to investigate the effect of Pediococcus acidilactici, a Probiotic bacteria, on the growth performance, haematological parameters and Biochemical indices of freshwater fish Catla catla. Pediococcus acidilactici was administered orally at 10⁶ CFU g⁻¹ feed to fish for 3, 7, 15, 30, and 45 days. Only the fish fed the diet containing Pediococcus acidilactici showed significantly (P < 0.05) improved growth rates. The control group was fed without probiotics for the same period. Blood samples were collected at the intervals 0, 3, 7, 15, 30, and 45 days. The haematological parameters such as Total erythrocytes count (RBC), Haematocrit (Hct) and Haemoglobin concentration (Hb) were examined. The probiotic bacteria treated fish showed maximum percentage Total erythrocyte count, haemoglobin concentration and haematocrit concentrations over the control group. The plasma glucose concentration was significantly increased in fish fed with diet containing P. acidilactici. The LDH activities in plasma of Catla catla were significantly decreased where as AST and ALT were in comparable rates as the control in the fish fed with diets containing P. acidilactici.
