High-Content Screening Laboratory -- Columbia, Missouri

This is an example of a 72 hour post fertilization fli1:egfp zebrafish (3 millimeters long) imaged under transmitted light. The same imaging system with was used.

Behavioral Toxicology Laboratory -- Columbia, Missouri. 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.
