When to start feeding the shrimp, it is best to put the feed, there are many controversies, there are many misleading. For example, feedstuff manufacturers can often see instructions for feeding feeds in proportion to their body weight. The author has also seen such reports: Since the second day of seedling release, 0.5 kg of feed has been used for every 100,000 shrimps. If calculated according to this ratio, a 10-milligram shrimp pond will have 100,000 seedlings per acre, and 5 kg of feed will be put on the second day of release. This is a very wrong guide and will have serious consequences. For example, a shrimp farmer in the Beihai of Guangxi placed 7 million South American white shrimp on a 10 mu shrimp pond. From the second day of release, artificial diets were fed. In the 25 days after the seedlings were released, 800 kg of feed were dropped, and an average of 32 kg was fed daily. According to the breeders, there are fewer and fewer shrimps in the feedlots. The author proposes to look up the feed table and found that after 4 hours of feeding, there are still many feed residues in the feed table and there are abnormal individuals. Looking at the shrimp seedlings in the fishing pond, a number of dead individuals and remnants were found, and there was a lot of rot that stinks. Afterwards, the shrimp in the pond continued to develop and became more and more serious. The shrimp seedlings had to be completely drained and replanted. The farmers' shrimp seedlings lost 20,000 yuan and the feed lost 4,000 yuan, which further delayed the breeding time and caused huge losses in production. This was caused entirely by premature feeding and excessive feeding.
After the shrimp seedlings are released, it is most appropriate to start feeding them. The correct answer is: When did the juvenile start feeding on the feed table, and when did it start feeding?
The specific method is as follows: From the second day of seedling release, put one or two tablespoons of zero feed in the feed table, observe it 1-2 times a day, and if the feed in the feed table remains intact, it indicates that the juvenile has not started to feed artificial compound feed. , and drained the feed in the feed table, continue to test in the same way on the third day, until the feed in the feed table was eaten by the shrimp until the end of the test, and began feeding the feed the next day. When you start feeding, you should start from 0.5 kg and increase daily. After the above tests, based on experience gained, we can basically grasp the law of starting feeds properly, and we don't need to test them every day. This is the author's experience in raising shrimp, which is of great value for reference.
Shrimp farming has an extremely important and indispensable link. It is to cultivate basic food organisms. Guangdong shrimp farmers are also called fertilizer water. After this period of shrimp farming, there are a large number of zooplankton in shrimp ponds. If you put a glass of water in a transparent glass, you can see more than a dozen zooplankton swimming in the sunlight. If you use a more than 30 mesh migolok to gently fish on the edge of the shrimp pond, dilute it in a transparent glass and add water. It can be seen that many dense zooplankton are swimming. Therefore, the number of zooplankton in the pond is very alarming. From this time before the start of feeding, the juveniles are mainly zooplankton in the feeding pool. They have unsaturated fatty acids. It has been reported that 260,000 shrimps are stocked per acre and no feed is given within 12 days of seedlings. Young shrimp can also grow normally.
