How to use fish medicine correctly

The following details should be grasped in the correct use of fish medicine:

The main results are as follows: 1. Identify the disease, different drugs to prevent and treat different fish diseases, when treating fish diseases, we should make a correct diagnosis of the disease and prescribe the right medicine in order to play the role of drugs and get the effect of treatment. Generally speaking, different diseases have different symptoms, but there are also some fish diseases, the symptoms are similar to the same, but the pathogens are different, it is necessary to carefully diagnose and distinguish in order to choose the most effective treatment drugs.

2. Drug performance fish medicine can be divided into two categories: chemical medicine and Chinese herbal medicine, these drugs have their own physical and chemical properties, if their characteristics are ignored, although the drug is symptomatic, the correct use will sometimes be ineffective. For example, bleach easily dissolves in the air and loses available chlorine; quicklime converts into powdered calcium carbonate for a long time and becomes invalid; the water temperature of dissolved copper sulfate cannot exceed 60 ℃, while fish worms must be soaked in water above 60 ℃.

3. Drug dosage all drugs have a certain action concentration, small and ineffective, but large will cause poisoning. The area and water depth of the fish pond should be accurately measured, and the water volume of the pond should be calculated (the body weight of the fish in the fish pond should be accurately estimated). Then convert the drug dosage according to the drug concentration, so that the drug can play a safe and effective role. At the same time, fish pond environment, water quality also have a certain impact on drugs, water and fertilizer, serious pollution should appropriately increase the dosage of drugs.

4. The method of medication

The method of medication should be determined according to the type of pathogen, drug performance and fish condition. Body surface parasites are suitable for sprinkling treatment, digestive tract parasites should be taken internally, and bacteriosis is generally treated with sprinkling method. Soluble drugs can be sprinkled and taken internally, while insoluble drugs can only be taken internally. If the fish has lost its feeding ability, it should be treated with sprinkling, and the fish should be taken internally if they have the feeding ability. Antagonistic drugs, such as insecticidal and quicklime, cannot be used at the same time. Generally speaking, the effect of oral administration is more complete; if the pathogen mainly invades the body surface of the fish, it should be sprinkled, and if the pathogen mainly invades the fish, it should be taken orally; to prevent fish disease, it is better to combine sprinkling and oral administration. At the same time, fish disease is often the result of the simultaneous action of several pathogens, treatment should be first worm before bacteria, that is, the first treatment of parasites and then treatment of bacterial diseases, so as to avoid repeated infection. Repeated use of drugs in a fish pond should also be avoided so as not to make the pathogen resistant.
