Rare earth is used to prevent fish diseases and promote long growth. Generally about 5 yuan per acre of rare earth, you can increase production of 20-30 kg of fish. With rare earth fish, one can improve the survival rate of fish. After feeding rare earth, the survival rate of grass carp increased by 28.6%, the survival rate of carp rose by 14.3%, and the survival rate of carp increased by 20%. Second, it can increase production. Rare earth can promote the growth of fish. According to reports, using rare earth to raise grass carp, the yield per mu can be increased by 26.4%, the production of carp increased by 33.6%, the carp increased by 22.8%, and carp increased by 24%. The reason why rare earth fish culture can prevent diseases is that the rare earth can inhibit the growth and reproduction of germs. To promote the growth of plankton in the water; Second, rare earth ions can react with the toxins secreted by pathogens to reduce and eliminate the toxicity of toxins; Third, rare earths can stimulate the fish's appetite, promote the digestion and growth of fish, enhance fish disease resistance, As a result, the fish production has increased significantly. To achieve the above objectives, we must first pay attention to the use of rare earth. Use 50 grams of rare earth nitrate to add 50 kg of water to dry feed or 20 kg of water to mix with 400 kg of mixed green material to feed the fish. Feed it once every 3-4 days. Each time you should choose 5-7 pm. Next, look at water quality using rare earths. Rare earth is used in yellow-green, mung bean-colored water, and has good effect; it is used for dark blue, gray-yellow turbid or yellow-brown water, and the effect is poor. Third, master usage. The amount of rare earth can not be too large, otherwise it will inhibit the growth of fish because the concentration is too high. In addition, it is better to use pond water instead of well water when dosing rare earth mother liquor, so as to avoid precipitation of rare earth under alkaline conditions.
