The giant freshwater prawn (Macrobrachium rosenbergii) (15-22g in intermolt) was exposed to different concentrations of Saponin (0, 0.3, 0.6, 0.9, and 1.2 mg/l); Formalin (0, 5, 10, 20, 30 mg/l); and Dipterex (0, 0.1, 0.2, 0.3 mg/l) for eight days. The parameters, including hemolymph osmolality, Na+, K+, Cl-, Ca2+, Mg2+, oxyhemocynin, protein, pH, total hemocyte count, PO, and O2- were examined after 8 days. Saponin and Dipterex negatively affected the physiological and immune responses of prawn, but Formalin did not. For prawns that were exposed to Saponin, there were no significant changes in hemolymph osmolality, Na+, K+, Cl-, Mg2+, and O2-. However, there was a significant change in Ca2+ and the total hemocyte counts; but a significant difference in oxyhemocynin, protein, pH, PCO2, PO2, HCO3-, TCO2, and PO. For prawns that were exposed to Dipterex, there was a significant decrease in hemolymph osmolality, Cl-, pH, PCO2, PO and O2-, but had no significant changes in Na+, K+, Ca2+, Mg2+, oxyhemocynin, protein, PO2, and total hemocyte counts.
