Five methods to improve the efficacy of fishery medicine
The viscosity of the improved adhesive should be strong, otherwise the drug is easy to be lost in water. Standard flour is a better raw material for binder. It is best to make pellet bait or ball bait for swallowing fish.
Fish with food attractants have such a keen sense of smell that they can still be identified even if 1 gram of alanine is dissolved in 1 million liters of water. For example, Chinese herbal medicines with strong flavor, such as star anise and Angelica dahurica, are ground into fine powder as food attractant, mixed with 10% to 20% of fish medicine, or added to fried soybean flour, wheat flour, etc., all have obvious food attraction effect.
The drug carrier is used to dissolve the fish medicine in a little water, and then sprinkle it evenly on the bait to feed the fish. The rice grains can also be soaked in the fish medicine solution and fed to the fish. Liquid fish medicine can also be injected into the body to feed the fish, and the effect is very satisfactory.
The combination of traditional Chinese and western medicine can not only improve the curative effect, but also reduce the cost, such as rhubarb, Scutellaria baicalensis, Phellodendron amurense, andrographis paniculata, Polygonum polygonum, Radix Rehmanniae, etc., mixed with sulfonamides and other western medicine. the efficiency can be several to dozens of times higher than that of Chinese herbal medicine alone.
The difference between prevention and treatment in the prevention of fish disease, you can first feed ordinary bait, so that strong fish to eat, and then feed bait, so that weak, poor eating ability of fish to eat bait. In the treatment of fish disease, you should first feed bait, so that healthy fish and newly sick fish eat more bait.
