This patent is to protect the method and apparatus for controlling, removing, preventing and/or inhibiting the accumulation, colonization or otherwise fouling of aquaculture fish farm pen nets with marine organisms, plankton and algae. The method and apparatus whereby this is accomplished involves the formation of a copper ion plume in and around the aquaculture fish farm pen nets. In general, the copper must be in an ionic form to be most effective in controlling, removing and inhibiting marine growth (fouling) on aquaculture fish pen nets. The mechanism is, believed to be, attributed to the positively charged ions that attach to the negatively charged cell wall of the microorganism and destroy cell wall permeability. The apparatus by which this ionic plume is generated is through an electrolysis process. Although electrolysis can be made to work under a variety of methods and for different applications, this patent provides an optimal method for creating a copper ionic concentration that is specific and unique to the aquaculture fish farms industry. The method of using electrolysis has been used in the marine environment for many years and all over the world to protect vessels and to protect the marine water-intakes from fouling with marine organisms. However, the method and application of using electrolysis to create a copper ion plume to protect aquaculture fish farm pen nets is unique, this method and application has never been done before. The electrolysis method uses two dissimilar metal electrodes. The cathodic electrode is stainless steel (but can be a graphite rod or other equivalent material). The anodic electrodes are copper and aluminum, where the aluminum provides corrosion protection. The oxidation of the anodes is by electron loss. The positive metal atoms of the metal electrodes oxidize to form positive metal ions, which form a plume (within the electrolyte or sea water) that may range in size and shape depending on the input variables such as voltage, electrical current, size of electrodes, but will also be dependent on ambient conditions such as temperature and salinity of the marine environment. Because the variables for creating the copper ionic plume can range so drastically, the scope of the protection afforded by the patent is specifically for the application, as it applies to the protection of aquaculture fish farm pen nets. The electrodes are connected to a DC electrical power source of 2.2Volts using an electrical current of 160mAmps (although this may vary depending on the desired plume size and ionic concentrations). The copper concentration of the ionic plume will range from less than ( < ) 0.01 ppm to 0.1 ppm. These concentrations are sufficient for controlling, removing, preventing and/or inhibiting the accumulation of marine growth (fouling) on aquaculture fish farm nets
