Technology of catching loach yellow powder in cable cage

From mid-spring to Mid-Autumn Festival, it is the season when loaches eat vigorously. You can pull nets in fishermen's fry and fish ponds, or catch loach in ponds with specially woven nets. During the operation, the obstacles in the water, especially the wooden stakes specially set in the farm, are removed first, and then the fishmeal, fried rice bran, wheat bran and other fragrant bait are made into hard bait and put into the farm as bait. When the loach is foraging in the foraging ground, the loach can be caught quickly by putting down the net, and the catching rate is high. This trapping method is based on loach's habit of looking for hidden things such as aquatic plants and roots to live and feed. Bags and polyethylene bags are used to put broken nets, leaves, aquatic plants and so on. And put bait in the water to lure the loach, and regularly lift the bag to catch the loach. This method is mostly used to catch loach in rice fields. When the weather is fine, drain the water in the fish tank and ditch in the rice field slowly, then slowly inject the water into the fish tank and ditch at night, and put the loach bag into the fish tank at the same time. Put some leaves, water plants, etc. Let it swell in the bag and put the bait. The bait is made of fried rice bran, wheat bran, silkworm chrysalis powder, fish meal, etc. Mixing with equal amount of soil or humus, and drying. Bait can also be wrapped in polyethylene mesh. When working, put the dough wrapped with bait into the bag and feed it in the bag to catch loach. This method should be carried out from April to May, especially in the daytime. From August to winter, you should put the bag at night and take it out before the sun rises the next morning. The effect is better. If there is no sack, you can also cut the straw mat into 60 cm long and 30 cm wide, put the bait ball or bag on the straw mat, tie the two ends of the straw mat tightly, gently enclose it in the middle, and then put it in the rice field, with the upper part slightly exposed from the water, and then catch some weeds and other things, so that loaches can feed in the straw mat and catch a large number of loaches. Drugs can be used to drive away loach cultivated in rice fields. The commonly used medicine is tea wilt, and the dosage is 5 ~ 6 kg per mu of paddy field. First, put the tea leaves in firewood and bake for 3-5 minutes, then take them out, grind them into powder while they are hot, and soak them in clear water for 3-5 hours before use. Reduce the water depth of the rice field to about 3 cm, and then set fish nests at the four corners of the rice field. The fish nests are made of silt, and the nest surface gradually inclines, which is 3 ~ 8 cm higher than the water surface. The size of the fish nest depends on the number of loaches, and the nest surface is 30 ~ 50 cm wide. The pesticide should be applied in the evening, and the liquid medicine should be evenly sprinkled in the rice fields, but no pesticide should be applied in the fish nest area. The next morning after application, the water in the fish nest is drained, and you can catch loach. There is no need to make a fish nest in a rice field with a fish pit at the drain. At night, the medicine is gradually and evenly sprinkled from the water inlet to the water outlet, and no medicine is added near the fish pit at the water outlet, so that the loach can be driven to the fish pit without medicine, and the loach can be caught in the fish pit with a net the next morning. Loach can be sold in the market. Misgurnus anguillicaudatus with smaller specifications can be moved to other places for temporary rearing. Misgurnus anguillicaudatus can be returned to the paddy field for breeding after the efficacy of the drug disappears (about 7 days). Attention should be paid to this method: the medicine must be prepared with the use, the concentration must be strictly controlled, and the spilled medicine must be uniform. The surface of the fish nest should be higher than the water surface, and there should be no sediment above the water surface in other places. The dry pond releases the water in the pond to catch loach, which is generally carried out in the autumn when the loach mud has a small appetite and does not drill mud for the winter. Or, if the above methods of fishing and raising loach are left, we have to fish loach in the dry pond. The method is to drain the pond water first, and then according to the size of the adult loach pond, dig several drainage ditches with a width of 40 cm and a depth of 25-30 cm at the bottom of the pond, and dig holes near the drainage ditches to make the bottom of the pond dry, so that water will accumulate in the ditch pit, and loaches will gather in the ditch pit, so that they can fish with nets. If the pond is not fully fished out, you can fill the bottom of the pond with water for several hours, and then slowly release the water until there is only water left in the ditch, and you can continue fishing with nets. If there are still loaches left in the pond, they will be submerged at the bottom of the pond for one night, and the water will be released slowly before the sun comes out the next day, and then they will be fished out, basically all the loaches in the pond can be fished out. Drainage from rice fields to catch loach is usually carried out after rice is ripe or harvested in late autumn. The water in the rice field can be drained slowly twice. When the first drainage is exposed to the surface of the rice field, the loach will swim to the fish ditch or fish tank to live. The second drainage is carried out 1 ~ 2 days after the first drainage, mainly to drain the water in the fish ditch and fish tank. When loaches are concentrated in fish tanks and fish ditches, they are first caught with nets, then caught with nets made of iron wire together with loaches, picked out and put in containers, and finally all loaches in rice fields are caught with the help of human hands.
