September 15, 2005 - Two natural shark repellent compounds were successfully tested using the tonic immobility protocol on lemon sharks and nurse sharks. One compound is water soluble, and both pose no significant odors. The low price and availability of these compounds is very exciting. The compounds will be scaled up and evaluated on larger shark populations for February 2006. Stay tuned!
