Research on Chinese sturgeon has focused on
artificial culture, spawning, and population dynamics.
Zhao et al. (1986) and Yi (1994) investigated the
distribution and abundance of juveniles from the
Yichang reach to the estuary. They found juveniles
concentrated at the river estuary during the period
May–September, and almost all the young fish found in
the estuary were younger than 1 year old. Juveniles
develop their capacity for hyposmoregulation by
salinity challenge at the river estuary.
