• An investigation has been carried out into the changes in blood chemistry which occur during the migration of young sturgeon and spawned adults from freshwater into saltwater and of the migration of prespawning adults in the reverse direction by Magnin (1962).
• Strict regulation of the catch was introduced in the Soviet Union in 1976 in order to prevent overfishing of the sexually mature sturgeons in the river.

• Information on the spawning period, spawning behavior, and other details of the reproductive biology of green sturgeon in the Columbia River is lacking (Oregon Department of Fish and Wildlife and Washington Department of Fish and Wildlife 1995).
