Swimming paths of control (left) and copper (right) exposed fish
Behavioral Toxicology Laboratory — Columbia, Missouri. Swimming paths of control (left) and copper (right) exposed fish demonstrate changes in swimming behavior detected following exposure to metals. Such changes can impact ability of fish to survive.
