Roe
From Cookipedia
Roe or hard roe is the fully ripe internal ovaries or egg masses of fish and certain marine animals, such as shrimp, scallop and sea urchins. As a seafood roe is used both as a cooked ingredient in many dishes and as a raw ingredient.
Caviar is a name for processed, salted roe consumed as a delicacy.
The term soft roe or white roe denotes fish milt (the seminal fluid of fish, mollusks, and certain other water-dwelling animals who reproduce by spraying this fluid, which contains the sperm, onto roe).
