Quick Summary: Trout roe is smaller (3mm) and sweeter, ideal for delicate canapés (€90-130/kg). Keta salmon roe is large (5-7mm), bursting, vibrant orange, perfect for blinis and sushi (€110-150/kg). Mojama is NOT roe — it's salted and cured tuna loin, with a concentrated savory flavor, to be sliced thinly and eaten with EVOO (€60-90/kg). All three are high-end products but belong to different categories: two fish roes + one cured fish.
This is one of the most frequent questions at the counter. "Is trout roe the same as salmon roe?" "And mojama? Is that roe too?" The short answer is: the first two are fish roe from different species; mojama is something else entirely — it's cured tuna. Let's break it down.
The Confusion: What Do They Have in Common?
All three products are sold under the label "sea salazones" (cured seafood) or "Mediterranean / Pacific gourmet product." They share:
- Preservation by salting.
- Concentrated marine flavor.
- Use as a premium ingredient in small doses.
- Similar shelf positioning and price.
But they are three very different products in terms of origin, texture, flavor, and culinary use. Anyone who confuses one for the other ends up buying something they didn't expect.
Trout Roe in Detail
Trout roe comes from female river trout or farmed trout (Oncorhynchus mykiss, rainbow trout, primarily). They are the smaller cousins of salmon roe:
- Size: 2.5-3.5 mm (smaller than salmon).
- Color: light orange, sometimes golden or almost yellow.
- Texture: finer skin than salmon, more subtle "pop."
- Flavor: sweeter, less marine, less intense.
- Typical Origin: Pyrenees, Cantabria, France, Italy, USA.
- Price: €90-130/kg.
They are the ideal choice for those who want to start with fish roe or for more subtle canapés where you don't want the roe flavor to overpower the rest.

Salmon roe, especially the Keta variety (Oncorhynchus keta), is the global benchmark. More details in our complete guide to salmon roe.
- Size: 5-7 mm Keta, 3-4 mm Coho.
- Color: vibrant orange to deep red.
- Texture: firm skin, generous "explosion" when bitten.
- Flavor: intense marine-fatty, salty, with a sweet finish.
- Typical Origin: North Pacific (Russia, Alaska, Japan).
- Price: €110-150/kg Keta, €140-180/kg Sockeye.
Mojama (Salted Tuna Loin) in Detail
Here, the category changes completely. Mojama is NOT roe — it is red tuna loin (Thunnus thynnus) or common tuna (Thunnus albacares) dry-salted and air-dried for 15-25 days. It is a Mediterranean cured fish with Phoenician origins (over 2,500 years old).
- Size: whole pieces from 200g to 2kg, dark garnet-brown color.
- Texture: firm, "cured meat," sliced very thinly with a sharp knife.
- Flavor: concentrated salty-marine, strong umami, similar to cured ham of the sea.
- Origin: Cadiz (Barbate, Conil), Murcia, Almería mainly.
- Price: €60-90/kg (200g - 1.8kg).
It is eaten in thin slices with EVOO, or grated over pasta. It is to cured seafood what Iberian ham is to cured meats: a product of long curing, high in sodium, intense in flavor.

When to Use Each
Use trout roe when:
- You want to introduce someone to fish roe (milder flavor).
- The canapé is very subtle and you don't want the roe to overpower (cream cheese, avocado).
- You have children or guests sensitive to strong marine flavors.
Use salmon roe when:
- You want a powerful visual effect (vibrant orange color).
- The dish demands impact: blinis with crème, sushi, pasta with lemon.
- You are topping other fish or avocado and want it to stand out.
Use mojama when:
- You want a "meaty" tapa without serving meat.
- You're looking for a classic Mediterranean appetizer (vermouth + mojama + EVOO).
- You want to grate it over pasta or salad (replaces parmesan in umami flavor).
Bottarga: Mojama's Italian Cousin
To complicate matters further: there is bottarga, which is indeed fish roe but cured as a solid salted product. It comes from the entire roe sac of mullet or tuna, salted and air-dried in a block. Amber-brown in color, it is grated like parmesan over pasta.
Therefore, if you ask me "is bottarga roe?", the answer is yes — but its culinary use and form are more similar to mojama than to loose roe spheres. More details in our article on bottarga, mojama, and Mediterranean salazones.

Conclusion
The three products share shelf space but belong to distinct categories. Trout roe = delicate entry into the world of roe. Keta salmon roe = accessible luxury with visual impact. Mojama = Mediterranean sea ham. If you have an event and are unsure: all three together on a platter with EVOO, picos, cream cheese, and a glass of dry fino make an appetizer that can hardly be criticized.

View cured seafood collectionFrequently Asked Questions
Is trout roe the same as salmon roe?
No. They are from the same family (salmonid roe) but different species. Trout produces smaller (3mm) and sweeter roe; Keta salmon produces larger (5-7mm) and more marine-explosive roe. Both are valid and compatible.
Is mojama roe?
No. Mojama is salted and cured tuna loin, not roe. What is cured roe is bottarga (from mullet or tuna), which is a different product.
Which has more salt?
Mojama, by far: 2,500-3,500 mg sodium/100g. Roe: 1,000-1,800 mg. That's why mojama is eaten in thin slices and small portions (10-20g per person).
Which is the most economical option for an event?
Mojama if you need quantity: €60-90/kg goes a long way in thin slices for many people. For visual canapés: trout roe at €90-130/kg is more affordable than salmon roe.
Can all three products be combined on the same platter?
Yes. A "Cured Seafood" platter with sliced mojama, salmon roe in spoons, and trout roe in another, accompanied by EVOO, picos, cream cheese, and a good dry fino or cava. A top-tier appetizer.
How long do they last once opened?
Roe (trout or salmon) once opened: 3-5 days in the fridge with cling film directly touching the surface. Mojama once opened: 1-2 months vacuum-sealed in the fridge or 2-3 weeks wrapped in paper and refrigerated (being very salty, it lasts longer).
Which pairs best with wine?
Trout and salmon roe: brut nature cava, manzanilla en rama sherry, Albariño. Mojama: dry fino sherry, manzanilla, white vermouth, young Mediterranean red (non-tannic).
