ULTRASONIC ERADICATION OF SEA LICE ON FARMED FISH

摘要

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.

1. A method for treatment of fish to remove parasitic, noxious aquatic organisms having gas pockets therein, from the fish, comprising the steps of:
1) providing a fish herding passage element with ultrasound transducers on a periphery thereof and in a number sufficient to provide ultrasound treatment of the fish being herded therethrough at a normal herding rate and at a sufficiently high enough frequency to kill the parasitic, noxious aquatic organisms; and 2) herding fish therethrough, with the application of ultrasound from the ultrasonic transducers at the sufficiently high frequency and at a herding rate sufficient to enable each fish to be exposed to the ultrasound, for the acoustic cavitation and killing of parasitic, noxious aquatic organisms thereon.
