How to prevent fish fulminant hemorrhagic disease? Introduction to practical methods
In autumn, as fish grow rapidly, pond farming density increases, water quality is prone to deterioration, and the reproduction rate of various pathogenic pathogens accelerates, making it very easy to trigger fulminant hemorrhagic disease. The preventive measures are as follows: 1. Before the fry and fingerlings are put into the pond, they must be soaked and disinfected with 1%-2% salt water. The soaking time depends on the fish's physique and the temperature. When conditions permit, fish fingerlings can be soaked with fulminant hemorrhagic disease vaccine. 2. Change water and increase oxygen in a timely manner. Keep the water quality fresh and change the water frequently. If conditions limit water changes and it is inconvenient, quicklime can be slaked into slurry and splashed over the whole pond, and at the same time, aerators should be used reasonably.

What kind of fish is the Red Wen Fish? Introduction to the characteristics of the Wen Fish variety
Originally named Wen Yu (patterned fish). As early as the late Ming Dynasty, after goldfish moved from pond culture to basin and vat keeping, their color varieties gradually increased. To distinguish them from the earlier goldfish, people called them "Wen Yu," meaning "fish with patterns." This is recorded in the Ming Dynasty book "Kao Bo Yu Shi." The Wen Fish has a short, broad body shaped like a triangle, with a pointed head like a mouse's head, which is its distinguishing feature; its fins are well developed. It is the earliest variety among the Wen group and evolved directly from the grass goldfish. Japan's Red Ryukin originated from China's Red Wen Fish. Originally only red, through years of breeding, its colors increased,

How is potato processed? An introduction to several common processing methods
I. Making jam from potatoes. First wash the potatoes clean, remove any rotten or sprouted parts, then peel off the skin, place them in a steamer and steam until cooked, then take them out and spread them to cool. Next, rub them through a grater into a uniform potato mash and set aside. Put white granulated sugar, water and sour water (that is, the sour water used in a vinegar workshop; mix a small amount of thin rice porridge with bran, place it in a vat, transfer it from vat to vat for one week, once a day, and the filtered sour water is used as a vinegar starter) into a pot and boil until 110°C, then pour the potatoes into the pot, and use an iron shovel to constantly turn them, pressing while stir-frying, until the potatoes

What to Do About Pigs' Bad Habits? Introduction to Clever Solutions
Pen escaping: Trim the upper eyelashes of a pen-escaping pig short, and trim them again once they grow long. This way, when the pig raises its head to escape the pen, its eyes will be irritated by wind, light, and dust, creating a sense of fear. After several times, the pig will no longer escape the pen. Wall chewing: Pigs often chew walls because of insufficient salt intake. Generally, the salt content in the diet of 60-90 kg fattening pigs should reach 0.25%, and the salt content in the diet of breeding boars should reach 0.35%. Biting and fighting: When pigs from different pens are housed together, biting and fighting often occur. If
