Abstract: A method, and device for removing sea lice from salmon with use of a salmon herding passage tube, with ultrasound transducers on the periphery thereof, in a number sufficient to provide ultrasound treatment of the salmon being herded therethrough at a normal herding rate and at a sufficiently high enough frequency to kill the sea lice. Salmon are herded therethrough, with the application of ultrasound from the ultrasonic. The method and device also include removal of the lice from a salmon cage or enclosure with feeding fish into an enclosure having ultrasound transducers situated on the inner periphery thereof and providing an attraction such as a white light which attracts noxious parasitic aquatic organisms and applying ultrasound from the electronic transducers within the enclosure.
