What term describes the white sturgeon's migration from saltwater/estuaries upriver to spawn?
Answer
Anadromous
The migratory behavior of the white sturgeon is defined by its movement pattern relative to spawning grounds. The species exhibits an anadromous life cycle, which specifically means that adults migrate from larger bodies of water, such as marine environments or coastal estuaries where they feed, into freshwater river systems to reproduce. The river systems function as the necessary nursery and spawning habitat, contrasting with the ocean or deep river pools, which are utilized primarily as adult feeding areas. This pattern necessitates connectivity between marine/estuarine zones and specific upstream river locations.
