dc.description.abstractBiochemical and physiological changes in Penaeus monodon on exposure to salinity stress conditions were studied. Total haemocyte count (THC), total protein concentration (PC), phenoloxidase (PO) activity, respiratory burst and osmolality were measured in low (3‰) and high salinity (55‰) stressed shrimps in comparison to control shrimp samples maintained at 28‰ salinity. THC (18 ± 2 x 106 cells ml-1) was significantly lower in the shrimps exposed to high salinity stress at one week interval when compared with the control group (38 ± 2 x 106 cells ml-1) while no significant difference was observed in THC between the control and low salinity stressed shrimps at any time interval. Total protein concentration was maximum at 6 h interval under low salinity (195±10 mg ml-1) and at 48 h under high salinity (219±15 mg ml-1) conditions. Respiratory burst in the haemolymph was significantly high at 24 h in low salinity (3.71±0.01) and high salinity (0.905±0.01) stressed shrimps. Significant decrease in osmolality levels in low salinity stressed group was identified at 6 h whereas, in high salinity stressed group, maximum increase was at 48 h. Moisture content and lipid in shrimp muscle were significantly (p<0.05) higher in low salinity stress conditions than in high salinity conditions. Total ash content was significantly high at 55‰ salinity, whereas, no significant difference was observed in protein content in the muscle tissues of tiger shrimp maintained at 3‰ and 55‰ salinity conditionsen_US
