Throughout the ages, anchovies have been praised, it is known for its "tender and fat fish", known as the "king of fish", is the delicious pursuit of diners.
As soon as I walked into the Shanghai Yinhe Aquaculture Professional Cooperative, I was attracted by the beautiful scenery of the water and the sky. In the cooperative's ponds, there are a number of economic fish such as American anchovies, Murray cod, yellow shellfish and so on.
According to the person in charge of the cooperative, there are a variety of aquatic products raised in more than 130 acres of ponds in the cooperative, such as hairy crabs, Australian freshwater lobsters, American anchovies, Murray cod, etc. have reached the listing specifications and began to supply the market during the eleventh period, and were well received after entering the market.
The cooperative's American anchovies are all raised in such round ponds and carefully fed. The American anchovy is very delicate, it can not leave the water, out of the water is dead. Secondly, it cannot see the poor environment of survival, and the scope of activities must be large. The digestive system is fragile and the intestines are short, so it is necessary to forage for food in constant motion and not stop for a moment. The water temperature requirements are higher, below 7 degrees Celsius or above 30 degrees Celsius, they are on the road of hunger strike.
The cooperative has independently configured a water circulation culture system for each breeding round pond, and the bottom water in the pond is automatically discharged through the system, and after multiple purification, it re-enters the breeding cycle. The whole process requires only a small amount of water replenishment, which greatly saves water resources. At the same time, the water circulation in the round pond of aquaculture flows, and the fry swim against the water, increasing the amount of movement, and the meat quality will be more delicious.
In addition, the system is also equipped with automatic sewage purification, liquid oxygen and air oxygenation, air constant temperature, intelligent alarm and other functions, as long as which equipment fails, or there is a problem in the breeding process, the system will alarm, remind the staff to deal with it in time, and ensure that the delicate fish fingerlings can grow healthily in the breeding pond.
In addition, the tailwater that appears during the breeding process will enter the specially opened tail pond, precipitate, filter, and oxidize and recycle to achieve water conservation and reduce environmental pollution of natural water bodies.
