Yangtze River white sturgeon body length of 2 to 3 meters, weight 200 to 300
kg, mainly living in the Main Tributary of the Yangtze River below Yibin, fierce,
healthy, staple fish, but also shrimp, crabs, etc., rapid growth, has been recorded to
the longest body up to 7 meters. White sturgeon is a ferocious carnivorous fish
that feeds on fish. Like most sturgeon, white sturgeon is a spawning migration.
Sturgeon live mainly in the large rivers of the northern hemisphere and in the
shallow coastal areas of the water. As an important link between oceans and rivers
for information and material exchange, it is an indicative species of ecological
status and a reliable indicator of aquatic biodiversity in the Northern Hemisphere.
The mouth of the Yangtze River white sturgeon is elongated and sword shaped,
with a pair of short whiskers on its abdomen. My eyes are very small. The mouth is
large, inferior, arcuate, and the upper and lower jaws have fine teeth. The gill pore
is large and the posterior edge of the gill membrane is pointed. The body surface
is smooth without scales. It inhabits in the middle and lower reaches of rivers and
sometimes enters large lakes.
