Carp is a fish of the genus Euplotus. There are more than 70 species of carps in the world, and more than 20 species have been discovered in China. Carangidae is a common marine fish that is widely distributed in tropical, subtropical and temperate waters. Although they are produced in the sea, they have a wide range of adaptation to salinity. They can normally live in seawater and brackish water. Some species can fully adapt to freshwater life and are the main fishes in coastal mariculture and brackish water pond culture. The main species for breeding are crickets (commonly known as Aconitum argentinalis and barley), barracuda (commonly known as the red-eyed oystercatcher, and yellow cricket), and lunatic shuttlebone (commonly known as razor clam). According to historical records, the eel farming industry began in the Ming Dynasty. The eel's body is slender, showing a bar-type, and the coastal masses also call it "squid." Carp is tender, delicious, and nutritious. Fish contains 22% protein and 4% fat. As early as 3,000 years ago, squid has become one of the noble foods of the royal family. The squid is also known as a squid and says that it tastes like a squid. Especially the squid before the winter solstice, the fish is the most full, the abdomen are back, especially plump, and often used as a seafood restaurant in the hotel restaurant. In addition to being appreciated as a food, squid also has its nourishing effect. In the Ming Dynasty Li Shizhen's "Compendium of Materia Medica," it contained: "Eel meat, smells flat and non-toxic, treats appetizers, benefits five internal organs, and is fat and healthy. Salmon is an omnivorous fish, mainly benthic diatoms and organic debris. It also eats some small aquatic animals and is suitable for polyculture with other domestic fish in ponds. In general, about 1,500 to 3,000 squid are reared for 3 to 5 centimeters per hectare, and they can grow to 400 to 500 grams in that year, with a yield of about 1,000 kilograms. When workers feed, they can feed some grain and oil by-products such as bran, bean cake, bran residue, and alcohol as feed to supplement the deficiency of natural feed. Squid breeds eggs in the ocean, and eels that are caught from the coast must be raised and desalinated before they are suitable for transport. For every 1/15 hectares of holding ponds, about 100,000 bonito seedlings can be placed, initially raised in seawater added with 1/4 freshwater, and the proportion of freshwater gradually increased until fresh water is used last. The whole process takes about one week. When desalting, feed should be properly fed to prevent loss of fish body. Trout species caught in fresh waters of estuaries can be stocked in ponds without dilution.
