Tibet is known as the "Asian water tower"
Abundant water resources
It has created rich fishery resources
however
Artificial aquaculture is affected by special environment
Most of them need to rely on the mainland market
After the efforts of generations of researchers
Aquaculture technology in our region is becoming more and more mature
Later, fresh fish and shrimp bought in the market
Maybe it's all raised by ourselves in Tibet
Three "containers" form a circulating system

Yesterday afternoon, the reporter came to the aquaculture base of the Academy of Agricultural Sciences of the autonomous region and saw a lot of fish in large and small pools“ This is a sturgeon with a long life; Here are golden trout and rainbow trout. They are artificially bred after being introduced from other places. At present, the technology is very mature. " Zhang Bingyi, deputy director and associate researcher of the Fisheries Institute of the Academy of Agricultural Sciences of the autonomous region, told reporters. At the base, the reporter saw three large objects similar to containers. Zhang said: "at present, we are doing the key technology of plateau unit circulating water aquaculture, that is, the practical control demonstration project. This is the most key of the project, which is called plateau unit microcirculation water aquaculture system."

Through the explanation, the reporter learned that the three "containers" constitute a complete circulating system, with breeding tanks on both sides and water treatment tanks in the middle. Both sides are used for breeding, which can automatically control all kinds of operations in the whole breeding process, and will be further optimized in the future; The water treatment tank in the middle is mainly used for disinfection, filtration, oxygenation and water temperature regulation. The three boxes are interconnected to form a microcirculation system, which greatly saves energy.

"The project started in 2016. When all the equipment arrived in May this year, we started breeding." Zhang Jingqun, head of the aquaculture farm of the Academy of Agricultural Sciences of the autonomous region, said, "what we are doing is shrimp farming, because there is no place to raise shrimp in Tibet, but there is a great demand for shrimp in the local market. We want to change this situation, so we are mainly doing shrimp farming experiments."
Subsequently, under the leadership of Zhang Jingqun, the reporter went to a breeding ground. Zhang Jingqun gently pulled up a square cage submerged in the water“ Look, this is green shrimp. " I saw a few transparent small green shrimps on it, which looked very lively.
The reporter learned that what is being done is the winter experiment of green shrimp“ See if they can survive this winter well. If the effect is ideal, we will carry out the next experiment, that is, put them in the incubator we just saw. " Zhang Jingqun said.
In addition to green shrimp, the base will breed Macrobrachium rosenbergii next year, which is a large freshwater shrimp native to Southeast Asia. It has the advantages of fast growth, wide diet, good meat nutrition, short breeding cycle and very good economic benefits.
"At present, it is in the preliminary test stage, but it has not yet reached the production stage. When the technology is fully mature, it can be promoted in the whole region, and then we can eat the local shrimp. There is no need to worry about the reduction of freshness caused by long-distance transportation, and the transportation cost can be greatly reduced. " Zhang said hopefully.
