Preparation methods of several Earthwork Fish drugs

In the prevention and treatment of fish disease, if the fish medicine can be prepared by using green plants or traditional Chinese medicine on the spot, it can prevent red skin disease, enteritis, Gill rot and other common diseases, avoid toxic side effects, and save expenses. The simple preparation methods of several kinds of fish medicine are introduced as follows:

Sanhuang powder rhubarb, Huangmeng and Huangcen were prepared by the proportion of 5 ∶ 3 ∶ 2. When in use, adding 1 kg of Sanhuang powder and 0.4 kg of salt to every 10 kg of fish concentrate feed, adding appropriate amount of water to make granular bait, once a day for 5 days, the therapeutic effect is remarkable in the early stage of the disease. After the advanced stage of fish disease, because the foraging has stopped, the effect of feeding bait is not ideal. Sanhuang powder should be mixed into 1.5ppm solution and sprinkled in the whole pool, such as copper sulfate sprinkled with 0.5ppm, once a day for 3-6 days. Good results can be obtained.

Chinese nutgall per cubic meter of water is sprinkled evenly in the whole pool with 2-3 grams of gallnut decoction. The collected fresh gallnut cotyledons can also be stacked in a corner of the pond in the form of compost, with a dosage of 1520 kg per mu, stirring the pool water once after 10 to 12 days and once a month after 1 month. the above method can promote the gallnut soaking solution to penetrate into the water body, thus having the effect of disinfection and sterilization. It has a good effect on the prevention and treatment of red skin, enteritis, rotten Gill and other diseases.

Masson pine leaves per mu with 1.5 kilograms of Masson pine leaves, mashed and added 50 grams of salt, mixed with green ingredients to feed. You can also take 40 kg of fresh Masson pine leaves per mu of water, chop and grind and then add 25 kg of water to sprinkle all over the pond, and you can also choose 50 kg of fresh Masson pine per mu of water and turn it once a day at the inlet of the pond.

The tobacco stalk was dried by 5 kilograms and 7.5 kilograms, soaked in a bucket or tank with clean river water of 20 kilograms and 30 kilograms for 2 days, then sprinkled with dregs in the whole pool. Each time before entering the fish or during the high incidence period of fish disease, it can be used to clear the pond and sterilize once, which can effectively prevent and cure the occurrence of fish disease. After the occurrence of fish disease, you can smoke. The leaf stalk was soaked in water at 50kg / mu, then soaked in 15kg / mu quicklime for one day, and sprinkled evenly with juice and residue, the therapeutic effect was obvious.

Castor leaves are 2kg / mu with castor leaves (stalks), chopped and beaten and sprinkled evenly in the whole pool, which can effectively prevent the epidemic of fish disease. After the occurrence of fish disease, castor leaves of 4kg per mu can be chopped or beaten and mixed in the bait for 3 days, once a day, with a good therapeutic effect. In order to ensure the efficacy, fish food should be stopped before feeding castor leaf juice. To sprinkle the juice evenly, it should be carried out on a sunny day.
