what is fish eggs called

Fish eggs are commonly referred to as "roe". The term "roe" applies to eggs from various marine animals, including fish, scallops, lobsters, and shrimp. Fish roe can be sourced from any type of fish, such as salmon, trout, cod, paddlefish, or whitefish. However, to be considered caviar, the roe must come from sturgeon, or fish of the Acipenseridae family. Caviar is a delicacy made from the salt-cured roe of sturgeon. Other types of fish eggs used in sushi include tobiko, masago, ikura, tarako, mentaiko, sujiko, and kazunoko.
