Comparing Tuna vs Salmon
The 6 Key Differences Between Tuna and Salmon:
1. Habitat & distribution:
Tuna and salmon overlap in the Atlantic ocean. But tuna is found in tropical and temperate salt waters around the world, and salmon inhabits both salt and fresh water in the Atlantic and Pacific oceans. Tuna is more common, but salmon is more popular for recreational fishing.
2. Physical appearance:
In a comparison of Tuna vs Salmon, it’s fairly easy to tell the two fish apart. The tuna has a sleek, round body compared to the long, slender body salmon have. Tuna has a round head instead of the salmon’s angled one, and many spots instead of few or none at all. It has a crescent-shaped tail rather than a forked one and tends to be longer and heavier than salmon.
3. Taxonomy:
Tuna is a bony fish in the Scombridae family along with mackerel and bonito. Salmon is a ray-finned fish in the Salmonidae family along with trout, freshwater whitefishes, chars, and graylings. Both are in the class Actinopterygii of ray-finned fishes, a subdivision of bony fishes.
4. Commerce:
In the United States, twice as much tuna is sold as salmon. 5 out of 8 species are most important for recreational and commercial fishing: Skipjack, yellowfin, bigeye, albacore, and bluefin. Salmon is considered a delicacy and therefore commands a higher price in any form, while 6 out of 7 species are most important for commerce: Chinook (King), Coho (silver), pink (humpback), red (sockeye), salmo salar (Atlantic), silverbrite (chum or dog) salmon.
5. Nutrition:
Tuna is higher up on the food chain and consumes smaller fish that are contaminated with mercury and other heavy metals, so limiting tuna intake due to concerns about mercury is sensible. There are some important differences in nutrients, though, especially if you’re seeking to fulfill certain dietary needs. Tuna is a leaner source of protein, containing more protein and being lower in calories, fat, and cholesterol. Salmon has more omega-3 fatty acids, important antioxidants which neutralize free radicals. It is high in vitamin D and vitamin B12 and because of its soft, digestible bones, is also a good source of calcium.
6. Flavor:
The nutritional differences are very evident in the unique flavor of each fish. Tuna is a lean protein with higher iron and has a coppery, meaty, oily taste with dark meat that turns dark pink when cooked. Salmon is a fattier fish with an oily, moister, richer taste with orange or pink meat that turns pale pink or whitish when cooked.
