In recent years, with the continuous improvement of aquaculture technology in Baotou City, the benefits of pond aquaculture have become the target of fish farmers. However, under certain pond conditions, pond water quality regulation and fish disease prevention have become problems that plague farmers. Talk about the problem of "four changes" in disinfection of fish, so as to prevent some farmers from entering the misunderstanding:
First, change the non-drainage disinfection to drainage disinfection. After the water in the pond is drained and sterilized by sunlight irradiation, the bacteria can be effectively killed. If the pond contains fish species or fish that cannot be listed, a temporary pond can be dug on one side or a corner of the pond to raise the fish, then drain the water in the pond and allow the pond to be sterilized by sunlight. Normally, it can be re-injected into the fresh water after sunny weather for about a week.
Second, change the drug to be administered directly for the release of the drug. Disinfect the pond with quicklime or bleaching powder and apply it unevenly and the effect is poor. The effect of splashing and sprinkling on water is ideal after it is opened. If disinfected with quicklime, the average depth of water per acre of pond is 100-150kg of quicklime, digging the pit first at the pond, and turning the quicklime into water to splash it with hot water.
Third, change to see the disease to prevent the main prevention and control combination. If the fish are treated with drugs after the onset of illness, they have often missed the opportunity to prevent and treat them, and the loss is also greater. The correct method should be to disinfect the fish, feed, food, and tools before the epidemic of fish diseases. Feeding the feed should be "quality, quantity, timing, and positioning." Once the disease occurs, the cause must be immediately identified and the patient should be given appropriate medication.
Fourth, change the mixed medication for the individual medication. If several kinds of fish medicines are used together, chemical reactions are likely to occur, resulting in failure of the medicines and even occurrence of toxic and side effects. Therefore, whether it is to splash drugs or use drug ingredients, not a variety of drugs and mixed use, it is best to use 1-2 drugs alone. In addition, the dose must be accurate.
