What kind of fish is this? I don't even know if I should let go.

Hello, this is Chinese sturgeon, an ancient and rare fish unique to anadromous fish and China. One of the most primitive fish in the world. As early as 1 0,000 BC, the Chinese sturgeon was called the king of tuna. Acipenser sinensis belongs to ACIPENSER. Sturgeon first appeared in the early Triassic 230 million years ago and has continued to this day. It lives in the Yangtze River valley in China and can't be seen anywhere else. It is really a "living fossil".

Acipenser sinensis is spindle-shaped, with a long snout at the top and four mouthparts in front of the mouth. The mouth is located on the ventral surface, which is elastic and can be stretched into a tube. The body is covered with five rows of vertically arranged bone plates, one on the back, two on the side and two on the abdomen, and each row has thorns. Sturgeon is a rare ancient fish left over from Mesozoic10.5 billion years ago. Between cartilage and hard bone, the degree of ossification of bone generally decreases. The central axis is an elastic notochord without ossification of vertebral body, and most of the cartilaginous shells along the skull are not ossified. The caudal fin is curved, the base of the lateral fin is broad, and the dorsal fin is opposite to the gluteal fin. The ventral fin is located in front of the dorsal fin, with spiny scales at the base of the fin and caudal fin, spiral valves in the intestine, anus and drainage holes close to the base of the ventral fin, and the opening of fallopian tube far from the ovary.

Acipenser sinensis is a large individual with a long life span, up to 40 years old. But its sexual maturity is late. According to research, in the spawning population, males are generally 9-22 years old and weigh 40-125 kg; Female fish 16 ~ 29 years old, weighing 172 ~ 300 kg. According to the literature, it weighs 560 kilograms and is a huge fish. Because they are the largest fish in the Yangtze River, they are also called the "Yangtze River Fish King". It is observed that the average annual growth rate of Chinese sturgeon is relatively fast, with 5-8kg for males and 8- 13kg for females. But it takes 8 ~ 14 years from larva to adult.

You can eat. However, the Chinese sturgeon is a national first-class protected animal. Please don't eat it even if it is farmed! However, if it is artificially raised for more than three generations, it can be eaten, and the state will issue a special business license in the sale. If you want to eat, you should also see if there is any. It's ok to eat less. ...
