1、电解养鱼法日本最近研究出一项新成果:在网箱上安装电解装置,用其电解作用提高养殖鱼的生产速度与成活率。其具体作法是:在网箱框架两端,分别挂上阳极金属与阴极金属,作为阳极的棒状铝合金连接在电线上,电线的另一端与阴极的铜管相连接。阳极也可用镁、锌及其合金,接上电阻与电源后,微弱电流流入网箱内形成电场。所生成的氧化铝或氧化镁等有吸聚浮游生物与小杂鱼的作用,还能阻止细菌侵入鱼体,使鱼不易患病.养殖实践证明,经过6个月饲养的鱼能达到5.2公斤,成活率达98%.
1, electrolytic fish culture Japan recently developed a new achievement: the installation of electrolysis device in the cage, with its electrolysis role in raising the production speed and survival rate of farmed fish. The specific practice is: at both ends of the cage frame, were hung anode metal and cathode metal, as the anode rod aluminum connected to the wire, the other end of the wire connected to the cathode of the copper tube. Anode can also be used magnesium, zinc and its alloys, connected to the resistance and power supply, the weak current into the cage to form an electric field. The resulting alumina or magnesia sucked together plankton and small trash role, but also to prevent bacteria invade the fish, so that the fish are not prone to disease. Breeding practice has proved that after 6 months of feeding the fish can reach 5.2 kg , Survival rate of 98%.
