Lumpfish caviar is one of the less costly types of caviar, a delicacy made of salted fish eggs. The lumpfish is a thick-skinned, lumpy cold-water fish found mostly in the North Pacific, but also in the North Atlantic and Arctic oceans. Fish eggs, called roe, have important nutrients. The caviar made from roe retains many nutrients. However, like all caviar, lumpfish is high in sodium and cholesterol.

In the United States, the lumpfish is not caught for its skin, which is inedible. The lumpfish, common in the waters of New England, is caught only for its roe. The lumpfish yields tiny, black eggs classified as hard roe, which are female eggs. Male fish eggs are called soft or white roe. Lumpfish roe is dyed red or black and heavily salted to make caviar, usually served as appetizers or hors d'oeuvres. The bright red lumpfish caviar makes a striking garnish. A tablespoon serving of red or black lumpfish caviar contains 15 calories.
