Re: What is the difference between caviar vs. fish roe?
"Caviar" is a subset of "fish roe."
Traditionally, the term "caviar" has been applied to the lightly cured eggs of several species of sturgeon found in the Caspian Sea. The term has been extended to other sturgeon species found elsewhere, as well as to the roe of entirely different genuses of fish including paddlefish, capelin, lumpfish, salmon, and others.

They refer to the same thing: fish eggs. However, the term roe refers to the fish eggs (or male fish sperm) themselves while caviar is roe that has been salted or "cured" and then placed in tins for storage and aging. In the United States and Canada, any product that is only labeled caviarmust come from sturgeon roe. You can check many examples on https://globalseafoods.com/collections/caviar
