Behavioral Alterations in a Simple Predator-Prey System Due to Sublethal Exposure to Mercury

Henry J. Kania and James O’Hara



After a 24-hr exposure to sublethal mercury concentrations of 0.1, 0.05 and 0.01 ppm Hg++, the ability of mosquitofish to avoid predation by bass was impaired.  Fish exposed to 0.005 ppm Hg++ were not affected.  The degree of effect showed positive correlation with mercury concentrations.
