The news of the extinction of the white sturgeon has touched the hearts of many citizens and readers. "The news says that white sturgeon are extinct, but why did you see them in the vegetable market?" Mr. Hu, a citizen of Wuhan, sent a photo to the Yangtze River Daily reporter, and the size of the fish in the photo was very similar to that of the extinct Yangtze River white sturgeon, with a long mouth.
Mr. Hu said that the photo was taken on the 15th of last month in Gutian Sanlu, when he saw a roadside vegetable stall with vendors selling fish, and the variety of fish was not common, so he took a few photos. The news of the extinction of the white sturgeon reminded Mr. Hu of the photos he had taken before. He asked, "Is this a white sturgeon?" ”
On the 4th, the Yangtze River Daily reporter asked the doctor of the Institute of Hydrobiology of the Chinese Academy of Sciences in Han and learned that the fish taken by Mr. Hu was indeed very similar to the white sturgeon. Liu Fei and Wang Xi, the two doctors of the institute, looked at the photos and unanimously decided that "this is the Spoon Sturgeon of the United States!" ”
Both the white sturgeon and the spoon sturgeon are species of the spoon sturgeon family of the suborder Spoon sturgeon. The white sturgeon is closely related to the spoon sturgeon and is very similar in appearance, the biggest difference is that the white sturgeon's kiss is like a log stick; while the spoon sturgeon's kiss is flatter, like a duck's beak, so the spoon sturgeon is also called a duckbill fish.
According to experts, spoon sturgeon live in the slow-moving waters of the Mississippi River. This large freshwater fish can grow up to 220 cm and weigh more than 90 pounds. Spoon-sturgeon takes its name from its distinctive snout, which is flattened paddle-shaped and about one-third of its body length. Spoon sturgeon is delicious in meat, rich in collagen and nutritious, and is a feast dish.
