Is platypus fish a protected animal?
Spoon-nosed Sturgeon, which is called duckbill fish by many people, originated in the United States. Our country carries on the management according to the national second-level priority protection of aquatic wild animals. However, due to the opening of aquaculture in recent years, platypus was originally a second-class protected animal in China, and it is not illegal for restaurants to sell farmed fish.
It is understood that the spoon-nosed Sturgeon, native to the Mississippi River Basin in the United States, is a large freshwater economic fish that has lived on the earth since 300 million years ago (that is, during the dinosaur period). It is one of the only two species of Acipenser in the world. Together with the Chinese Sturgeon and the White Sturgeon in the Yangtze River, it belongs to the family Sturgeon of the order Sturgeon.
Duck-billed fish with strong adaptability, rapid growth, docile temperament and short food chain is the only fish that feeds on zooplankton among all Sturgeon. Its bait comes from a wide range of sources, and is easy to raise and catch, so it is suitable for aquaculture in reservoirs, lakes and ponds.
