Is red caviar real caviar? If so, why is it so cheap?

Answer 1:

Due to the fact that it is manufactured from cod roe. The Russian Sturgeon, which dwells in the Caspian and Black Seas, produces real caviar.

Answer 2:

Red caviar is manufactured from smoked catfish or cod roe, but “genuine” beluga caviar is merely salted and never smoked or seasoned and comes from the beluga sturgeon!
