Abstract: A device (10) for trapping and killing marine organisms (14) such as animal plankton, salmon lice and other parasites, comprises a body (12; 12?) configured for submersion in water (15). The body (12; 12?) comprises at least one light source (16) configured and controlled for attracting said marine organisms, and an internal cavity (20) having an opening (20?) for fluid communication with at least a portion of the water. The light sources (16) are arranged inside the cavity (20) and arranged and controlled to emit light waves through said opening and into at least a portion of the water. At least one positive electrode (24; 24?; 24?; 32) is arranged in the cavity and electrically connected to a low-voltage power source (26; 27; 30), and at least one negative electrode (15a) is arranged in the water and electrically connected to said power source (26; 27; 30).

Abstract: The present invention relates to an electrochemical device for releasing ions, comprising an electrical circuit comprising a first electrode and a second electrode adapted for providing a galvanic cell when the electrodes are exposed to a fluid constituting an electrolyte, and a boost converter adapted for amplifying a potential generated between the first and the second electrode. The electrical circuit further comprises a third electrode connected with an output side of the boost converter, wherein the second and the third electrode constitutes an electrolytic cell powered by the galvanic cell when the electrodes are exposed to a fluid. The present invention further relates to devices, such as a toothbrush or a shaver, adapted for being used in connection with a fluid, comprising such electrochemical device for releasing ions.
