Hanging water fish refers to some fish that are raised in different ponds after they grow into adults. They don't feed feed, don't feed grass, don't feed fish medicine, just drink clear water and eat plankton, which makes the fish "slim down". It is characterized by low fat, high protein and no hormones.

For a fish, a delicious fish should at least be firm, not muddy and sweet enough. But for cultured fish, the meat quality is often soft, the muddy smell is often pungent, and the fishy smell is naturally gone. So someone (said to have originated in Guangdong) invented hanging fish (also known as "slimming fish") to satisfy the picky appetite through temporary breeding.

Extended data:

Hanging water fish is favored by consumers, and the market price reaches 19.8 yuan/kg. The benefit of cultivating hanging water fish is considerable, and 750 kg of hanging water fish can be harvested per mu. Grass carp, crucian carp, pomfret and Guizhou fish can all hang water fish. Hanging water fish can also be mixed with silver carp. Silver carp can eat the feces discharged by hanging water fish and receive 750 kilograms of silver carp per mu.

Hanging grass carp refers to the temporary feeding of grass carp in the pond without feeding after it is transferred to the hanging pond. Generally speaking, this temporary feeding process lasts for 25 to 40 days. In the process of temporary feeding, no feeding is carried out, only necessary drug treatment and water change treatment are carried out. Grass carp will be scraped up and put into the market after reaching the listing standard.

Different from feed grass carp, the listing standard of the former generally refers to weight, while hanging grass carp is more complicated, and the standard mainly has three directions: body, taste and taste. The figure should be slender, the taste should be sweet and odorless, and the taste should be chewy.
