Manganese Induced Alterations in the Blood Pyruvate Levels of a Freshwater Indian Catfish Heteropneustes fossilis

K Nath, Nishith Kumar, Salahuddin Salahuddin

Abstract

Blood pyruvate levels of a freshwater Indian Catfish, Heteropneustes fossilis, were investigated following sublethal manganese intoxication (3440 mg/l MnSO4·H2O; 0.8 of LC50 96 h). Blood pyruvic acid levels registered a statistically significant elevation at all exposure periods. Maximum elevation of 53.33% was observed at 96 h.
