What does sturgeon mean?
A sturgeon is a large, ancient-looking fish with a long body, a pointed snout, and rows of bony scutes that give it an armored appearance. Sturgeons are cartilaginous fish, meaning that their skeletons are made primarily of cartilage rather than bone. They are valued partly for their roe, which is processed into the celebrated delicacy caviar. Many sturgeon species are anadromous: they live in rivers but migrate to coastal areas or the open sea to reproduce. Some can grow several metres long and live for many decades, making them notable members of the freshwater and coastal ecosystems in which they occur. Overfishing, dam construction, pollution, and the loss of spawning grounds have caused serious declines in several populations. In ordinary English, “sturgeon” most often refers to the fish, while “sturgeon roe” or “sturgeon caviar” identifies its culinary product.

Etymology of sturgeon
The English word entered Middle English through Old French esturgeon. Medieval Latin forms such as sturionem are generally traced to a Gaulish source related to forms in other European languages, including French esturgeon and the Germanic words German Stör and Dutch steur.
How sturgeon is actually used
The word normally denotes the fish itself. When it refers to its roe, context usually makes clear that the delicacy rather than the animal is meant.
