Processing Technology of Shrimp skin
Main raw materials: hairy shrimp, salt and so on. Equipment: iron pot, basket, running water stove.
Production method: the hairy shrimp are graded and selected, and those containing a lot of sundries should be screened with a sieve. If the raw material is not clean, wash it and put it in a basket to drain water. Each basket contains about 6 kilograms of hairy shrimp. You can cook in the following ways:
① turn basket cooking method. That is, fill a large iron pot with a diameter of 90 cm with 7 minutes of fresh water, add 2 kg of salt, boil, sprinkle with appropriate amount of salt (15 kg of salt for every 50 kg of prawns, 2.5 kg of salt for first-grade shrimp, 3.5 kg of salt for second-grade shrimp and 4.5 kg for third-grade shrimp), add the cover, open the cover after boiling, and move the basket with a basket needle. Let it rotate to make the shrimp ripe evenly. When the shrimp is straight, take out the shrimp basket and put it in a ventilated place to cool. Generally, change the water in the pot every 5 to 8 baskets, in case the water is too salty and affect the quality of the finished product.
② direct cooking method. Put a certain concentration of salt water into a large iron pot, boil and sprinkle the prawns into the pot water, boil for 2-3 minutes, then remove and cool.

How to raise shrimp well in midsummer
In the high temperature season in midsummer, hot weather, strong light, high water temperature and poor water quality affect the foraging and molting growth of shrimp, which can easily lead to disease and death of shrimp. Farmers should do a good job in the following management work in the high temperature season: with the increase of water temperature and the growth of shrimp, the water depth should be continuously increased, especially in the middle and later stages of culture, the water level must be increased to 1.8m~2m, and the high temperature period should be kept above 2.2m. During the high temperature period, full drainage and full irrigation should be carried out, and the water temperature should be controlled within 30 ℃, so that the transparency of the water can reach 35cm.

Natural reproduction of koi
The selection of good parent fish is the key to the reproduction of koi. To adopt natural reproduction, we must first choose the parent fish that meet the standard. In the north, after spending the winter indoors, koi, formerly reserved as a species of fish, moved to outdoor fish ponds in mid-late March. At this time, parent fish should be further selected to obtain excellent offspring. (1) the selection of parent fish for breeding should generally have the following: strong physique, bright color, pure Lu system, obvious species characteristics, clear edge of color spots, no false edges, no defects, and smooth scales.
