The infection then spreads throughout the entire body. To assist in controlling this disease, report any suspected case to the nearest DNR office and keep the fish refrigerated until a biologist can inspect the tissue. Thoroughly dry all equipment and boat exteriors before using in other water bodies because the parasite spores may be present in lake water, but cannot survive drying. Drain all live wells and bilges. Because it is impossible to thoroughly dry these areas, disinfect with one cup of bleach in five gallons of water before moving to other water bodies.
