Abstract
Physiological observation on activity recovery of mercury exposed fresh water fish were done by using aquatic weeds. Five weeds constitute two floating weeds Eichhornia and Salvinia in surface layers, Chara and Hydrilla in the column layer and Vallisneria in bottom layer. Five experimental groups constituting five selected weeds were subjected to establish fish lethal concentration of mercury for a period of 48h, 96h, 144h, 192h and 240h to facilitate mercury absorption. All the data shows that mercury removal efficiency increases with increased time exposure. The present results indicate that maximum quantity of mercury was accumulated by weeds of IAMB rapidly up to 144h of exposure.
