Abstract	The present was study was made by exposing the Litopenaeusvannamei to environmental acidic [ ph 6.4] and alkaline [ ph 9.0] media for 24 hrs and studied the tissue somatic index ( TSI) and tissue proximate analysis of hepatopancreas was significantly lowered in both acidic and alkaline media similarly, the dry weight was also reduced in both media. In contrast, the water content was showed no significant change on exposure to alter ph media. The total carbohydrate content of hepatopancreas exhibited significant reduction in both acidic and alkaline medium on acute exposure. Total protein content showed differential pattern in hepatopancreas on exposure to alter pH media. The protein content was significantly decreased in acidic medium and elevated the same in alkaline medium. The total lipids showed decreased trend in both acidic and alkaline media on an acute exposure. It is observed that the environmental acidic and alkaline pH induced metabolic modulations in hepatopancreas, which lead to metabolic adjustment and provides increased survival value against the imposed pH stress.
