SIRF is sponsoring developmental research to maintain the health of farmed fish without the use of antibiotics or other drugs. Researchers at Virginia Tech are treating tilapia with an antibody produced at the University of Wisconsin to determine its effectiveness in preventing infection. The antibody will be applied through feed with dosing compared against a negative control. Fish will be exposed to Aeromonas hydrophila to determine the ability of the antibody to suppress infection. Successful responses to the antibody in this study will support expanded research to other species and pathogens.
