Morphology: Sturgeon is the oldest fish in the world, with large size and long life. Sturgeon is an existing ancient biological population, which originated in Cretaceous hundreds of millions of years ago and is known as the "panda" in water. Sturgeon is kept as an ornamental fish because of its peculiar shape. Sturgeon has a plow-shaped head, a low mouth, a curved tail and five ribs on its back. Both juvenile and adult fish have ornamental value, among which the juvenile ACIPENSER schrenckii (distributed in Heilongjiang Province) has been artificially raised as an ornamental fish since its successful artificial reproduction.
