Winter sheds should pay special attention not to overfeed. I recently went to a shrimp farm in Taishan City, Guangdong Province for technical guidance and found a water depth of 1.5 meters, an area of ​​4 acres, put 1.6 million tailed white shrimp, breeding for more than 40 days, the average body length 3-5 cm, a day Three feeds were cast, 22.5 kilograms each time, and 67.5 kilograms throughout the day. If the amount of shrimp ponds is estimated based on the feed amount, there will be about 2000 kg. The actual pool size is much lower than this value. When I personally checked, I found that after 4 hours of feeding, there was still a large amount of feed left, and the water started to change, indicating that the feed was seriously overdose. When asked why the farmer voted for so many feeds, he said that he did not raise shrimp. He was introduced from some publications and some shrimp farmers. Past or present, some books and magazines are misleading in the way they feed. For example, the author once read that a certain journal said that tomorrow, he will vote for fodder, and tomorrow he will follow the ratio of 0.5 kg of feed per 100,000 flies of shrimp, which should increase every day. If feed is fed in this way, serious consequences will result. . The author believes that after the fertilizer and water, and cultivate a good shrimp pond with good water color and transparency, if put 50,000 per acre, about 20 days will not eat artificial compound feed, but the intake of plankton in the pool. There have been reports that 260,000 shrimps were planted per acre, feed was not given within 12 days, and larvae grew normally. This is correct. It should be pointed out here that if ponds are not completely poisoned, there are predatory creatures such as small fish or white shrimp. Today, shrimps will be released and the feeds dropped tomorrow will be eaten. If this happens, feed should be started. Otherwise, the predator in the pool will eat shrimp seedlings because of hunger. Simultaneously use 5-8ppm tea bran to kill the fish.
