Roe (//) or hard roe is the fully ripe internal egg masses in the ovaries, or the released external egg masses of fish and certain marine animals, such as shrimp, scallop, sea urchins, and squid. As a seafood, roe is used both as a cooked ingredient in many dishes and as a raw ingredient.
The roe of marine animals, such as the roe of lumpsucker, hake, salmon, Atlantic bonito, mackerel, squid, and cuttlefish are especially rich sources of omega-3 fatty acids, but omega-3s are present in all fish roe. Also, a significant amount of vitamin B12 is among the nutrients present in fish roes.
The term soft roe or white roe denotes fish milt, not fish eggs.
Around the world

Upscale restaurants are not expected to offer it, but street vendors and smaller restaurants will make their first daily sales of it before they run out. Cojinova itself (considered a medium quality fish) is caught for its fish meal, not for its roe, which is considered a chance product. Sea urchin roe is considered a delicacy and it is used (at customer request) to add strength to ceviche.

Several sections of the Israeli cuisine include roe. In Modern Hebrew, roe is commonly referred to by its Russian name "ikra" (איקרה). When necessary, the color is also mentioned: white or pink, as appropriate. Israeli "white ikra" is commonly made of carp or herring eggs, while "red ikra" is made of flathead mullet eggs or, in rarer cases, salmon eggs. The term "caviar" is separate, and denotes only sturgeon eggs.
Ikra is served as a starter dish, to be eaten with pita or similar breads, particularly in Arab restaurants. It can also be purchased in stores, in standard-sized plastic packages. In home cooking it is similarly served as a starter dish.
In Judaism, roe from kosher fish—fish with fins and scales—is considered kosher. Like fish in general, it is considered pareve. Roe is considered kosher only if the fish from which it's harvested is kosher as well. This means that sturgeon roe is not considered kosher from an Orthodox Jewish perspective.
For most Orthodox Jewish consumers who keep kosher, roe or caviar must be processed under kosher supervision as well. The only exception to this rule is red roe, thanks to a widely accepted responsa by the Bais Yosef.

Russia and ex-USSR countries
In Russian, all types of fish roe are called "икра" (ikra, caviar), and there is no linguistic distinction between the English words "roe" and "caviar." Sturgeon roe, called "чёрная икра" (chyornaya ikra, "black caviar") is most prized. It is usually served lightly salted on buttered wheat or rye bread, or used as an ingredient in various haute cuisine sauces and dishes. It is followed in prestige by salmon roe, called "red caviar," which is less expensive, but still considered a delicacy. More common roes, such as cod, pollock, and herring are everyday dishes. Salted cod or pollock roe on buttered bread is common breakfast fare and herring roe is often eaten smoked or fried. The roe of freshwater fish is also popular but the commercial availability is lower. Soft roe of various fishes is also widely consumed, mostly fried, and is a popular cantina-style dish.

Stenbitsrom, the roe of lumpfish is naturally a bleak unappetizing gray, but is coloured black (to emulate Black Caviar) or orange (to emulate Löjrom). Stenbitsrom sells in much larger volume than Löjrom, but it has two drawbacks: it tastes little more than its salt and artificial additives, and the colour additives tend to bleed into other parts of the food you serve it with (such as a boiled egg), or to discolour the porcelain dish.
There is also a trend to use more Laxrom (Salmon roe), which is a natural orange colour, and has large diameter.
Roe consumed within the UK is generally soft roe as opposed to hard roe. Though not popular, herring roe is sold within many British supermarkets.
