%X Hydraulic projects in south China often suffer from the biofouling hazards of <i>limnoperna fortunei</i> which adheres to the surface of structures in high-density, changing the function of structure buildings and affecting the safe operation of hydraulic projects. Through researching the mortality characteristics of <i>limnoperna fortunei </i>under conditions of drying, high water temperature, ultrasound wave, and electric current, we discuss the feasibility of removing<i> limnoperna fortunei</i> using physical methods<i>.</i> Results revealed that <i>limnoperna fortune</i> died three days after being in dehydration condition at  28 ℃; and 10 hours in high temperature (44 ℃) ; when the water temperature is higher than 55 ℃<i>, limnoperna fortunei </i>died instantly contacting with water. Ultrasonic wave and high pressure electric current in water could also kill larva and adult<i> limnoperna fortune</i> effectively. Among the four methods, dehydration and high temperature are the most effective, while ultrasonic wave and electric current are of good prevention effect.
