which fish does caviar come from
Caviar refers to the salted eggs (roe) of the fish species, sturgeon. 1  Caviar comes from the Persian word Khaviar which means bearing eggs. Some eggs from other species ( such as salmon, paddlefish, whitefish, and lumpfish) may be labeled caviar if the name of the fish is included. The three main types of caviar beluga, sevruga, and osetra, refer to the sturgeon species the caviar comes from.
