Fish Roe Guide: Caviar, Ikura, Tobiko & Masago Explained
Fish Roe Guide: Caviar, Ikura, Tobiko & Masago
Fish roe is the broad term for fish eggs. Different species produce roe with very different size, texture, flavor and culinary uses. Sturgeon caviar, salmon roe (ikura), tobiko and masago should not be treated as interchangeable products.
For salmon roe, start with our Salmon Roe (Ikura) Guide or browse the Red Caviar & Salmon Roe collection.
1. Sturgeon Caviar
In the traditional and regulatory sense, caviar refers to salted roe from sturgeon. Beluga, Osetra and other sturgeon caviars vary by species, farm, cure and grade. For terminology and differences from other roe, see Caviar vs. Roe.

2. Ikura — Salmon Roe
Ikura is the Japanese term for salmon roe. The eggs are much larger than tobiko or masago and have a pronounced pop. Salmon species also matter: Chum, Coho, King and Pink Salmon Caviar can differ in egg size, membrane firmness and flavor.
3. Tobiko — Flying Fish Roe
Tobiko is flying fish roe commonly used in sushi. Its eggs are much smaller than salmon roe and have a fine, crisp texture. Commercial tobiko can be seasoned or colored, so appearance alone does not identify a specific preparation.
4. Masago — Capelin Roe
Masago is capelin roe. It is also small and commonly used in sushi rolls and garnishes. For a sushi-focused comparison of these roe types, read our Fish Roe Sushi Guide.

Nutrition
Fish roe can provide protein, marine omega-3 fatty acids and micronutrients, but exact nutrition varies substantially by species, cure, serving size and product. Cured roe can also contain meaningful sodium. Use the nutrition panel on the specific product when precise values matter. For salmon roe specifically, see our Salmon Roe Nutrition Guide.
Ready-to-Eat Roe vs. Raw Roe
Do not assume all fish eggs are ready to eat simply because they are fresh. Commercial cured caviar and ikura are different from Unprocessed Salmon Roe, which is sold for further preparation. Follow the product's handling and preparation instructions.
How to Serve Fish Roe
Sturgeon caviar is often served simply with blini, crème fraîche or toast. Ikura works especially well with rice, nori, eggs, potatoes and cold appetizers. Tobiko and masago are commonly used in sushi rolls and as garnishes.
Storage
Storage requirements differ by product, processing and packaging. Follow the label rather than applying one universal refrigeration or freezing rule to every type of roe. For salmon roe, use our Salmon Roe Storage Guide.
Professional Perspective
Global Seafoods North America has worked with salmon roe and seafood products for decades. When comparing roe, we focus first on species identity, processing, cure, cold-chain handling and the condition of the actual lot—not broad marketing terms such as “premium” or “superfood.”
