Salmon was not always a sushi ingredient. Atlantic salmon (Salmo salar) is the farmed species that changed this. In Japan, salmon was traditionally considered too fatty and too parasitic for raw consumption. The fish that built modern sushi culture was tuna, flounder, and sea bream. Salmon was a smoked or cooked ingredient.

That changed in the late 1980s when Norwegian trade representatives convinced Tokyo sushi restaurants to try farmed Atlantic salmon, which had been raised in cold, parasite-controlled conditions. The fish had consistent flavor, high omega-3 fatty acids content, and was mild in flavor, and safe to eat raw after being frozen to kill parasites. Within a decade, salmon had become the most popular sushi fish in the world.

Today it is the first fish most home sushi makers try. I started with salmon in 2021. A soy sauce and wasabi dip alongside perfectly sliced salmon over rice convinced me immediately. The fat content makes it forgiving, it tastes good even when your slicing technique is imperfect, and the bright orange color against white rice looks impressive immediately.

What makes salmon sushi-grade?

The FDA recommends freezing fish at minus 20 degrees Celsius for 7 days, or minus 35 degrees Celsius for 15 hours. This kills Anisakis worms and other parasites that live in ocean fish. Farm-raised Atlantic salmon has a lower parasite risk than wild-caught Pacific salmon, but freezing is still the safest approach for raw consumption.

When buying salmon for sushi, ask your supplier: was this frozen to FDA parasite-destruction standards? A reputable fishmonger or online seafood specialist answers this without hesitation. A regular supermarket fish counter may not.

What type of salmon is best for sushi?

Farm-raised Atlantic salmon is the most widely available and most consistent choice. Higher fat content and mild flavor make it beginner-friendly.

Farmed Atlantic salmon

The orange-fleshed salmon sold in most supermarkets and fish counters. Higher fat content, visible white marbling, mild buttery flavor. The fat content makes it more forgiving to slice and more visually striking on a plate. Farm-raised in cold-water environments (Norway, Scotland, Chile) under controlled parasite conditions.

For sushi, the belly section (harasu) is the most prized because of its highest fat concentration. The tail section is leaner with firmer texture. For beginners, center-cut pieces are the most consistent.

Wild Pacific salmon

Stronger, more complex flavor with less fat than farmed Atlantic. Sockeye has the deepest red color and boldest flavor. King (Chinook) is the highest fat content of wild Pacific varieties and the closest to farmed Atlantic in texture.

Wild Pacific salmon must be frozen to FDA standards before raw consumption. Most supermarket wild salmon has not been. Source from Japanese fishmongers or online specialists who confirm the freezing history.

How do you choose fresh salmon?

Visual check

Color is the most reliable freshness indicator. Deep, even orange with visible white fat lines. Brown edges or dull, faded color indicate age. The flesh should look moist and translucent, not opaque or dry.

Touch

Press one finger lightly into the thickest part of the fillet. Fresh salmon springs back immediately. If the indent stays, the fish is deteriorating.

Smell

Clean ocean smell. Any strong fishy or ammonia smell means the fish is past its peak for raw consumption. Buy from a fishmonger who handles fish in volume. High turnover means fresher stock. Ask when the fish arrived. Use the same day for best quality.

How do you slice salmon for sushi?

Cut against the grain at a 45-degree angle. For maki, slice 1 cm wide strips. For nigiri, slice 7 to 10 gram pieces at a slight angle.

Setting up

Remove the salmon from the fridge 10 minutes before slicing. Cold salmon is harder to cut cleanly. Remove the skin if present by holding the fillet skin-side down and sliding a sharp knife between skin and flesh with a gentle sawing motion.

For nigiri

Cut across the grain at a 45-degree angle. Each slice should be 7 to 10 grams, roughly 6 cm long and 2.5 cm wide, and 5 to 7 mm thick. The slight angle produces a wider slice that drapes over the rice mound more elegantly than a straight cut.

For maki rolls

Cut into strips 1 cm wide and 10 cm long, running with the grain. These strips lie flat in the roll without bunching.

For sashimi

Cut 5 to 7 mm thick slices across the grain. Uniform thickness matters more than perfect size for sashimi presentation. Arrange on a clean plate wrapped with strips of nori, alongside soy sauce, wasabi, and ginger.

The preparation guide covers the full technique with step-by-step instructions.

How do you store salmon?

Keep at 0 to 4 degrees Celsius. Use within 24 hours of purchase. Never freeze and refreeze. Thaw frozen salmon overnight in the fridge.

Leftover raw salmon that has not been served can be cooked the same day. Do not store cut raw sashimi-style slices for next-day raw consumption. Salmon that has been sliced and left in the fridge overnight loses texture and develops a stronger smell. Cook it with a hot pan and high heat rather than wasting it. The cooked fish is excellent in rice bowls or on toast.

Where do you buy sushi-grade salmon?

Japanese fishmongers who confirm freezing standards are the most reliable source. Online specialists like Catalina Offshore ship overnight.

For online delivery, specialists like Catalina Offshore Products (US) and The Fish Society (UK) ship vacuum-sealed sushi-grade salmon overnight with temperature monitoring.

Do not assume supermarket salmon is safe for raw consumption without asking. Most supermarket fish is intended for cooking and has not been frozen to FDA parasite-killing standards.
