Ultrasonic waves for the control of Limnoperna fortunei – the golden mussel

Abstract

In order to verify the effect of ultrasonic waves to control the invasion of the golden mussel, Limnoperna fortunei, three experiments were made with different numbers of individuals and for each experiment the sonicator device was using at 40kHz frequency. In addition, the tests varied in time and days of exposure of the mussels to ultrasonic waves. As a result, several numbers for mortality and decoupling of the analyzed samples were noted, with significant differences regarding the exposure time per experiment and days in which the samples were submitted. Thus, the use of ultrasound to descale and kill the golden mussels was efficient and may be an alternative to control the invasion of L. fortunei.
