Tor E. Horsberg

Name:	Tor E. Horsberg
Title:	Professor
Memo:	Research focus: The focus is on effects of veterinary drugs and toxins on fish. Uptake, distribution, excretion and metabolism of a series of agents have been studied. In addition, resistance development against commonly used delousing agents for sea lice has been studied in several projects. Another focus has been on the ability of fish to perceive pain.
