The present study was carried out to study of the haematology of the freshwater fish, Catla catla were exposed to herbicide glyphosate hijack® for 10, 20 and 30 days in laboratory condition. Several haematological changes such as RBC, WBC, HB, HCT, Blood Glucose, Total Cholesterol, Triglycerides, Total Protein were observed in fish blood would serve as a useful purpose in evaluating the toxic effects of herbicide glyphosate hijack® (41%). All the values were significantly decreased from control. The maximum decreased level of activities in all these blood values was at 30 days. It has been concluded that herbicide glyphosate hijack ® (41%) at sub-lethal concentration may alter the RBC, WBC, HB, HCT, total glucose, total cholesterol, triglycerides and total protein in blood in all the exposure periods.
