Meaning
A freshwater sturgeon species native to North America, valued for its roe (caviar).

Semantic Notes
Primarily a zoological and commodity term. Its use outside of fisheries, caviar trade, or regional North American contexts is rare. May be encountered in historical texts about the Mississippi River basin.
