The present study was to investigate the effect of Pretilachlor (PTC) in 7, 14 and 21 days with 3 different concentrations in fish Labeo rohita (L.rohita) in. The creatures were divided into four groups including control, Treatment I (1 mg/ L), Treatment II (3.9 mg/ L) and Treatment III (5.9 mg/ L). L. rohita were exposed to PTC for a period of 7, 14 and 21 days when compared to the control group. The blood tube glucose, protein, Hb, Hct, and erythrocytes situations were significantly (P<0.05) dropped throughout the treatment period when compared with the control for a period of 7, 14 and 21 days. Whereas, the values of erythrocyte and leukocytes indicators (MCV, MCHC, and MCH) were increased significantly (P<0.05) in pretilachlor treated groups (I, II and III) when associated with the control group. In conclusion, the present study emphasizes that pretilachlor at tested groups for a period of 7, 14 and 21 altered the haematological and biochemical parameters serve as an effective test system for environmental threat assessment of the submarine terrain.
