Life Cycle
Sturgeon are anadromous meaning they spawn in fresh water and migrate to salt water to mature.
The Chinese variety can be considered a large fresh water fish, although it spend part of its life-cycle in seawater, like the salmon.
The Chinese Sturgeon has a habit of upstream migration: they dwell along the coasts of China's eastern areas and migrate back up rivers for propagation upon reaching sexual maturity. It has the longest migration of any sturgeon in the world and once migrated more than 3,200 km (2,000 mi) up the Yangtze. The sturgeon's reproductive capacity is poor: it may breed three or four times during its life-cycle, and a female sturgeon can carry in excess of a million eggs in one pregnancy, which are released for external fertilisation when mature. The survival rate to hatching is however estimated to be less than 1 percent.

Famous quotes containing the words life and/or cycle:
“‘Pure experience’ is the name I gave to the immediate flux of life which furnishes the material to our later reflection with its conceptual categories.”
—William James (1842–1910)
“The cycle of the machine is now coming to an end. Man has learned much in the hard discipline and the shrewd, unflinching grasp of practical possibilities that the machine has provided in the last three centuries: but we can no more continue to live in the world of the machine than we could live successfully on the barren surface of the moon.”
—Lewis Mumford (1895–1990)
