A method of inhibiting fouling and blocking by marine organisms of sea water passages comprises passing an electic current between a pair of electrodes placed in the sea water such that the current concentration in the sea water is 0À06 to 1 amp. /cu. metre/ hr of sea water flowing in the passages. The electrodes are placed in the passageway or at the entrance thereto and the anode may be platinum, magnetic iron oxide, platinum plated titanium, carbon or platinum palladium and the other electrode may be mild steel or galvanized steel. As shown in Figure 3 sea water is pumped by pump 7 through intake 5 where electrodes 12 are located, through a leaching cell 6, flow-rate indicator 10 to a boiler condenser 8. The signals from indicator 10 are transmitted to electrolytic current regulator 11 which controls the current supplied to electrodes 12. The sea water passages may be made of iron, steel, copper or copper alloys.
