Min Yun: "Fish farming is not awkward and rich are faint." In the entire breeding process, prevention and control of fish diseases is an important link, and it is the key to improving the survival rate of fish fry and fingerlings and the yield and quality of adult fish. How to prevent and treat fish diseases in place can be achieved through the following measures: 1, establish a concept The prevention of fish diseases is mainly prevention, and the concept of "prevention" is more important than "governance." This day-to-day management is very important. It should be “four-determined†and “four-disposalâ€, that is, feeding and feeding: qualitative, quantitative, timing, and positioning. "Four eliminations" means: disinfection of fish ponds; disinfection of fingerlings; disinfection of feed, food, and tools; disinfection of water bodies. With day-to-day management, many fish diseases are completely controllable and avoidable. 2, identify the cause To understand the rules of the disease, understand the causes of fish diseases. The causes of fish diseases are very complicated. Some are external causes, some are internal causes, external causes are conditions, and internal causes are fundamental. The fish's living environment is an external cause. When the pH of the water environment is greater than 9.5 and less than 5, fish's death will be caused. The fish's constitution and immunity are internal causes, and the constitution is weak and it is easy to get sick. The analysis of the causes of fish is more likely to do more with less. 3, the right medicine The types of fish diseases are very complex and can be divided into four categories: skin diseases, rickets, intestinal diseases, and other organ diseases. According to different pathogens, diseases caused by viruses, bacteria, and fungi are infectious fish diseases; diseases caused by parasites are invasive fish diseases; in addition, there are various fish diseases caused by predators. If you do not prescribe the right medicine, you will be disinfected with water. This will not only fail to achieve the effect of "drug-to-disease," but will sometimes be counterproductive. 4, the difference between medication The fish have different sizes, different species, different susceptibility to fish medicines, and the amount of fish used is not the same. They should be treated separately. 5, accurate medication After the diagnosis of fish diseases, the dosage should be calculated based on the size of the pond, the depth of the water level, the cultured species, the water quality, and the stocking density. Accurate medication is the key to treating fish diseases. 6, alternating medication Practice has shown that long-term use of a drug can cause disease resistance of diseased fish and resistance to disease in ponds. Used alternately, the effect is better. 7, expired without Each drug has a certain period of validity. Some fish farmers are pursuing cheaper purchases of expired drugs or are reluctant to dispose of expired drugs and continue to use them. The results not only have no effect, they even produce toxic substances, often resulting in the death of a large number of fish poisoning. Such "savings" It is not worth the candle. 8, medication conditions Treatment of enteritis, must be hungry fish for two days, before feeding fish food bait; winter with 5% saline disinfection of fish species is very good; transport of live fish in summer, add 0.5% of salt, can improve the survival rate of transport. 9, pay attention to residue The selection of low-toxicity, high-efficiency fish medicines is the key to ensure the quality and safety of aquatic products. Clever use of traditional Chinese medicine recipes can also cure fish diseases. Such as control of small melon worms with chili powder, ginger, etc., the effect is also very good. 10, seek practical results Many fish farmers abuse drugs. In fact, fish diseases can sometimes be treated with the same disease or different diseases. The medicines used should be based on the effective amount of drugs, sales price and other factors to select the appropriate drugs to minimize the cost of drugs and improve the economy. benefit.
