There are seven tricks to improve the efficacy of internal administration of fish medicine.

First, the difference between prevention and treatment lies in the prevention of fish living in the water, the condition is hidden and difficult to detect. Once dead fish is found, the loss is great, and the treatment of fish disease is more difficult, which brings a lot of inconvenience. Therefore, we should actively implement the guiding principle of "no disease first prevention, early treatment of disease, prevention is more important than treatment", and establish the concept of prevention and drug application.

Second, the skillful combination of traditional Chinese and western medicine in the treatment of fish disease has the advantages of long effect, few side effects and low cost of prevention and treatment. Western medicine has the characteristics of rapid efficacy and high cost. Practice has proved that mixing some western medicine into effective Chinese herbal medicine can not only quickly improve the curative effect, but also reduce the cost. For example, Chinese herbs such as "Sanhuang" (rhubarb, Coptis chinensis, Phellodendron chinense), Polygonum polygonum, andrographis paniculata and Herba Euphorbiae are ground into powder and mixed with Jiejie and Keshan.

Wei, Yu Bikang and other western medicine, compared with the use of Chinese herbal medicine alone, the curative effect is nearly 5 times higher than 10 times. If it is found that there are parasites in fish, pine needles, duck foot leaves, black mullet leaves, eucalyptus leaves, cloth startling leaves fall into the pond to poison parasites and bacteria, the effect is long-lasting, not easy to relapse, less side effects.

Third, skillfully calculate the amount of fish medicine according to the average amount of bait in the pond for a period of time (under the premise that the fish grows normally and does not get sick, it is measured by a slight surplus after tasting the next day) multiplied by 20 times, the stock of fish in the pond can be calculated, thus the dosage can be calculated. For example, 600 jin of concentrate feed is routinely fed every day, and then multiplied by 20 times (600 × 20 kg 12000 jin), that is, the fish storage in this pond is about 120 jin.

About 00 jin, and then calculate the dosage according to the stock of fish.

Fourth, skillfully adding food attractants fish are more sensitive to the taste of salt and sugars. In order to stimulate the desire of fish to eat, an appropriate amount of food attractants can be added to the bait. For example, strong-scented Chinese herbal medicine star anise, cloves and garlic are supplemented with some salt to make food attractants with a concentration of 10% and 20%.

Fifth, the effect of skillfully using binder to coagulate drugs directly affects the forming time of bait in water, the forming time of bait is long, the feeding time of fish is prolonged, and the food intake is increased, which plays a direct role in the prevention and treatment of fish disease; the bait forming time is short, the fish drug is lost quickly in the water, the feeding time of fish is short, and the food intake is less, which weakens the effect on the prevention and treatment of fish disease. Not only waste fish medicine, but also delay the prevention and treatment of diseases.

The best time to get sick. Therefore, strong stickiness of @ # @ 245 flour, Mutz powder, glutinous rice flour and so on should be selected as adhesives. The adhesive accounts for 40% of bait feed, about 50% of the bait feed.

Sixth, skillfully select the simple fish medicine of the carrier and put it in the water, and the fish seldom ingest. Only when the fish medicine is skillfully mixed on the carrier can the efficacy be improved and the best effect of prevention and treatment of fish disease be achieved. The most suitable carrier is the paste of corn, soybeans, wheat, peanut bran, chaff, wheat husk and so on.

Seventh, whether the method of skillfully feeding bait is appropriate or not will directly affect the curative effect of fish medicine. Practice has proved that before feeding the bait, stop feeding for one day to make the fish hungry. The next day, when the weather is normal, the bait will be fed at 09:00 (some 4-5 p.m.) to achieve the purpose of preventing and controlling fish disease.
