Nuogan method to improve the efficacy of fish medicine
1. Improve the adhesive. The adhesion of the adhesive should be strong, otherwise the drug is easy to be lost in the water. Standard flour is a better raw material for binder. It is best to make pellet bait or ball bait for swallowing fish.
2. Adding food attractant. Fish have a sensitive sense of smell and can still be identified even if 1 gram of alanine is dissolved in 1000 tons of water. For example, the strong-scented Chinese herbal medicine star anise and Angelica dahurica dahur
3. Use drug carriers. The fish medicine is first dissolved in a little water, and then evenly sprinkled on the bait to feed the fish; the rice grains can also be soaked in fish medicine and fed to the fish; the fish medicine solution can also be injected into the body and then fed to the fish, and the curative effect is very satisfactory.
4. Combination of traditional Chinese and western medicine. Mixing traditional Chinese medicine into some western medicine can not only improve the curative effect, but also reduce the cost. Such as rhubarb, Scutellaria baicalensis, Cortex Phellodendri, andrographis paniculata, Polygonum polygonum, Radix Rehmanniae, etc. into powder, mixed with sulfonamides, furans and other western medicine, the efficiency can be several times to dozens of times than the use of Chinese herbal medicine alone.
