Qiqiao improves the efficacy of internal administration of fish medicine

1. Coincidence lies in prevention. Fish that live in the water are concealed and difficult to find. Once dead fish are found, the loss is great, and the treatment of fish disease is more difficult. 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.

two。 Skillful combination of traditional Chinese and western medicine. Traditional Chinese medicine has the advantages of long-term efficacy, few side effects and low cost of prevention and treatment of fish disease, while 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 herbal medicines such as "Sanhuang" (rhubarb, Coptis chinensis, Cortex Phellodendri), Polygonum polygonum, andrographis paniculata, and Herba Euphorbiae are ground into powders, which are mixed with western medicines such as Lijie, ketoxime, Yubikang, and so on, which are nearly 5-10 times more effective than using Chinese herbal medicine alone. If it is found that there are parasites in fish, pine needles, duck foot leaves, black mackerel leaves, eucalyptus leaves and cloth convulsion leaves can be used to kill parasites and bacteria with long-lasting effect, not easy to relapse and less side effects.

3. Skillfully calculate the amount of fish medicine. According to the average feeding amount in the pond for a period of time (under the premise that the fish grows normally and has no disease, it is measured by the slight surplus just finished the next day) multiplied by 20 times, the fish stock in the pond can be calculated, thus the dosage can be calculated. For example, 300kg of concentrate feed is routinely fed every day, and then multiplied by 20 times (300x20=6000 kg), that is, the fish storage in this pond is about 6000 kg, and then the dosage is calculated according to the fish stock.

4. Skillfully add food attractant. Fish are sensitive to the taste of salt and sugar. in order to stimulate the feeding desire of fish, an appropriate amount of food attractant 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%.

5. Skillful use of adhesive. The effect of adhesive coagulant directly affects the molding 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 loss of fish medicine in water is fast, the feeding time of fish is short, the food intake is less, and the effect on the prevention and treatment of fish disease is weakened. It not only wastes fish medicine, but also delays the best time to prevent and treat diseases. Therefore, strong sticky @ # @ 245 flour, wood 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.

6. Skillfully choose the carrier. The simple fish medicine is put 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 fish disease prevention and treatment can be achieved. The most suitable carriers are corn, soybeans, wheat, peanut bran, rice bran, wheat husk and other paste.

7. Skillfully bait. Whether the method of feeding bait is proper 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 prepared bait will be fed at 9 am (some 4-5 pm), which can achieve the purpose of preventing and controlling fish disease.
