Guangdong is famous for its pursuit of fresh ingredients, and the rich water environment in the Pearl River Delta has made large-scale freshwater fish farming here. The four major fish, silver carp and bighead carp, provide sufficient, high-quality and cheap protein for Chinese people. This sculpture, which stands on the street of Dongsheng Town, Zhongshan City, Guangdong Province, attracts the attention of passers-by and makes strangers here curious about Huan. Among the four major fish, herring and grass carp are also called black snapper and pomfret. What kind of fish is crispy pomfret?
In fact, this fish is not a special species. It is a common freshwater mandarin fish, also called grass carp. Ordinary grass carp eat a special feed, which can make the meat crisp. When people taste it, the taste will have obviously different feelings.
Grass carp turns into crispy pomfret, and the key to the problem lies in the mysterious feed. This is a special farm for breeding crispy carp. The technical person in charge said that the grass carp in these ponds are being crisped. What fish eat every day is the kind of special feed that can make fish crisp. The so-called special feed turned out to be ordinary broad beans. The broad bean is millet. Many people like to cook broad bean rice with rice, which is also a favorite snack of many people. But in fish farms, broad beans have become a special feed, which makes fish brittle.
According to the technical staff of the farm, grass carp began to feed broad beans after reaching 3 kg, and entered the embrittlement period of about 100 days. After the fish reach the ideal brittleness, the fish are sent to the hanging pond in batches. The so-called hanging pond is to raise crispy grass carp with water that has been purified by two levels. During the period, neither feed nor grass nor fish medicine was fed. Fish only drink the water in the pond. This is also what fish farmers often say about slimming fish. After this process, not only the fish is crisp and palatable, but also the muddy smell of freshwater fish is removed.
Pearl River Fisheries Research Institute has carried out research on key technologies of grass carp quality improvement and aquaculture emission reduction, invented patented aquaculture technology and processing technology for grass carp quality improvement, systematically constructed microbial community regulation technology for emission control in grass carp farming process, and created a zero-emission model in grass carp farming process. Using this achievement, the self-purification and zero pollution of farmland water system can be realized. (This article turns from approaching science.
