Salmon vs. Tuna: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on January 22, 2024
Salmon is a popular fatty fish known for its pink-orange flesh and migratory nature, while tuna is a large, fast-swimming fish, prized for its meaty texture and used extensively in sushi.

Key Differences

Salmon, a fish known for its distinctive pink to orange flesh, is celebrated for its taste and nutritional value, rich in omega-3 fatty acids. Tuna, with its leaner and meatier texture, varies in species from the smaller skipjack to the larger bluefin, and is a staple in many cuisines, especially in sushi and sashimi.
The life cycle of salmon is unique, as they are born in freshwater, migrate to the ocean, and then return to freshwater to reproduce. Tuna, on the other hand, are oceanic fish, spending their entire life in saltwater environments, often traveling long distances across oceans.
Salmon farming is a significant industry, with Atlantic salmon being the most commonly farmed variety. Tuna is harder to farm due to its size and migratory nature; most tuna consumed is wild-caught, though farming efforts are increasing, particularly for species like bluefin tuna.
In terms of cooking, salmon is versatile, suitable for grilling, baking, and smoking, and is often consumed in smoked form or as salmon fillets. Tuna is popularly served as steaks, canned, or raw in dishes like sushi and sashimi, celebrated for its strong flavor and firm texture.
Environmental concerns differ for both fish: overfishing and sustainability are major issues for tuna, especially for species like the bluefin tuna, while salmon farming raises concerns regarding pollution, disease, and escapement of farmed fish into the wild.
