In this season of shrimp and fish fat, he has a good harvest of Penaeus vannamei.
Yang Xinli has been in this industry for 29 years since he came into contact with aquatic products in 1993.
"I was originally raising freshwater fish, and the income was not very optimistic. In 2012, I accidentally learned about Penaeus vannamei, and I started to breed the first batch of shrimp fry in 2013. After so many years of exploration, these 'exotic shrimp' allowed me to harvest Quite a lot." Yang Xinli said.

The road to shrimp farming was not smooth sailing, and Yang Xinli still remembers the twists and turns of the year.
"When I raised shrimp for the first time, not long after the seedlings were planted, I found that a large number of shrimps in the pond had died. At that time, I didn't understand anything, so I followed the traditional aquaculture method to raise shrimp, but I lost everything." Anxious Yang Xinli asked around and was able to find the cause of the collective death of the shrimp fry. "It turned out that the living environment of the shrimp changed from seawater to freshwater."
How to successfully farm shrimp in fresh water has become a problem for Yang Xinli on the way of farming.
In order to raise shrimp well, he has traveled for three consecutive years in coastal cities such as Hainan, Zhejiang, Fujian and other local shrimp farming experts to learn techniques.
In order to learn breeding techniques, he worked and worked in the breeding base while learning from experience.

"Shrimp raising is like taking care of your own children. It requires great care. 25°C to 28°C is the best temperature for the growth of Penaeus vannamei. The pH value of the water quality should be between 8.0 and 8.6. The dissolved oxygen, ammonia nitrogen, Only when the nitrite is kept normal can the survival rate of Penaeus vannamei seedlings be improved." He told reporters that in order to adjust the water body suitable for shrimp seedlings, he eats and sleeps in the desalination workshop. After hundreds of attempts, he gradually mastered it. Aquaculture technology for desalinated water bodies.
"In addition to patrolling ponds in the morning and evening and improving water quality, attention should also be paid to preventing diseases and preventing the adverse effects of drought and rainy weather. When catching shrimp, the time and method of releasing the cages are also very particular." Talking about the white shrimp Yang Xinli's "Cultivation Classic" is right now.
Holding the prawns that had just emerged from the pond, he told reporters: "The shrimps raised in the Yellow River have thin shells, delicious meat, and rich nutrition. They are very popular. A pound of prawns can be bought for about 35 to 45 yuan, with ice packs. Packed and shipped in a reefer box, the shrimp can survive for 2 to 3 hours.”

"This year, 80 acres of shrimp have been farmed, and the output per mu is about 400-500 kilograms, which is a bumper harvest." Yang Xinli said that from the end of April to the time when the seedlings were put in, the shrimp farmed in the north has ushered in the best season for listing, "Now South America The white prawns are just in the market, and the daily sales volume is more than 100 kilograms, which are mainly sent to the aquatic market around Yinchuan, and the daily sales will increase in the later peak sales season."
