Traditional shrimp farming usually takes July 15 to August 15 as the closed fishing period, but in Zhang Dage's case, the closed fishing period is advanced to the end of June and the beginning of July, and it can be listed one and a half months in advance.
What is "135 mode"?
"135" mode means that shrimp can leave the pond for ten days, then enter the shed for thirty days, and finally enter the pond for fifty days.
The shrimp raised in this way not only has high yield, but also has large specifications.
The whole shrimp is green and white, with plenty of food in the intestine, clean, smooth and not dirty, and full cheeks, all of which are good shrimp.
Shrimp fishing also has a coup! Generally speaking, every time Brother Zhang catches shrimp, each basket will be put in oxygenated "ice water". Why? Brother Zhang said that every time he caught shrimp, he was alive and kicking. If you put them in ice water, they won't move, but will sleep temporarily. In this way, shrimps are more resistant to transportation and have a high survival rate. When they are transported to the market, they can still sell live shrimps.
In the era of 5G Internet of Things, white shrimp farming has also been guaranteed by the intelligent Internet of Things.
We walked around the breeding base in Qiaozhuang Town and found a blue device floating in many ponds, far from the water.
I asked the farmers here to know that although it is small, it can play a great role!
"Our smooth farming every year depends on it!" The farmer said.
"In the past, every time it was cloudy and rainy, I was worried about the lack of oxygen in Tangkou. I'm on tenterhooks all day and can't even sleep well.
Since I had it, I slept soundly all night, and my insomnia is all right! That sounds amazing. What kind of equipment is this so amazing?
Raise shrimp, raise water first, the water looks good and dissolves oxygen;
Dissolved oxygen is the key and difficult point of aquaculture. There is no effective scheme to monitor dissolved oxygen in traditional aquaculture, and it is too late to know that it is anoxic until the anoxic floating head and the cultured animals begin to die! The arrival of the 5G Internet of Things era will subvert the status quo of this industry! At present, the latest technology is to put a digital sensor at the mouth of the pond to monitor the dissolved oxygen, temperature and pH value of the pond in real time for 24 hours. No matter where you are, you can see the real-time water quality of the pond at a glance by picking up your mobile phone.
Even if you are thousands of miles away, the change of dissolved oxygen in the pond is under control.
When the dissolved oxygen is too low, it will automatically alarm and start the aerator to aerate, effectively avoiding the occurrence of hypoxia accidents in high temperature summer and improving the breeding efficiency.
