Bioaccumulation of cadmium: toxicity in Mugil cephalus

Abstract

A series of 12 lethal and sublethal concentrations of Cd were applied in seawater to determine LC50 for two sizes of fish. Fries were found to be more sensitive to Cd toxicity than juveniles. During 2, 4, 6 and 8 week exposure periods to graded Cd concentrations, mortality increased but no significant effect on growth occurred. From subacute experiments, the MATC for fries and juveniles were 0.05-0.02 ppm Cd2+/1 and 2-0.1 ppm Cd2+/1, respectively. Liver was found to accumulate the highest concentration of Cd followed by gill, muscle, alimentary canal and finally the heart.
