First, giant stingrays. Giant stingray is one of the freshwater fish found, the largest of which is 500 kilograms. It grows in the Mekong River basin, and it is not a common fish. It is somewhat similar to the rays in the sea (that is, it looks like the "plate" that was popular on the Internet last year). This kind of fish is also a relatively few species in the local area, carnivorous, with poisonous tail needles, and it is more dangerous in the waters.
Second, the giant catfish. The protagonist of the legendary story of the big catfish is the same species as the water monster in "Demon Journey to the West", and it is the most legendary among freshwater fish. It is a carnivorous fish and will actively attack its prey, including humans. This giant catfish also grows in the Mekong River basin, and can grow to a maximum of 450 kilograms. However, ordinary catfish can grow to a great size when they grow crazy. If there is a catfish of this size in a reservoir, it will definitely lose money if the fish pond is included in the waters.
Third, giant carp. Among the common fish, there is a genus of carp called Giant Carp, which is also very big, with a maximum length of 300 kilograms, and also comes from the Mekong River basin. The fish in this basin are relatively large, and biologists have to find out the specific reasons. Carp is not aggressive, and in many places, there is a saying that carp turns into dragons, so big carp will not be caught. The species are slippery scale carp, large scale carp and so on.
Fourth, the sparrow eel. For many areas, the finch eel is an exotic species and a highly aggressive fish. No matter whether it is fishing or catching fish, as long as such fish is seen in the waters of our country, it should be fished up first and treated at will. This kind of fish is also a black hand under civil disputes, and people in Baotang are often used this kind of fish yin, which can be up to 200 kilograms long.
Five, Chinese sturgeon. Chinese sturgeon, a native fish, is a big treasure no matter how big it grows. When it was a child, it was a bit like a sparrow eel. If it is not knowledgeable enough, it is easy to be cheated by unscrupulous merchants. Acipenser sinensis is a migratory fish, which grows in the Yangtze River basin.
Six, grass carp. Among the cultured fish, it is recognized that the grass carp grows bigger, with the largest growth of 170 kilograms. Generally speaking, grass carp raised for about three years can grow to 8- 10 kilograms only by feeding grass. If it is fed well and fed scientifically, it can grow even bigger. It belongs to economic fish species and has been widely cultivated and developed in southern China.
