Abstract
Toxicity of inorganic mercury to different life history stages of fresh water fishes,
Cyprinus carpio and Cirrhinus mrigala were demonstrated by static bioassays. 48 and
94 % of egg hatching occurred in controls at 72 and 24 h of experimentation in C. carpio
and C. mrigala respectively. While fish eggs in water containing mercuric chloride
showed delayed development as compared to the control. LC50, LC100 and safe concentrations
of hatchling, fry and :fingerling were calculated. Hatchling and fry were
observed to be more susceptible as compared to fingerlings of C. carpio and C. mrigala.
