In short
One serving each: 175 calories in salmon (3 oz, 85 g), 77 calories in tuna (3 oz, 85 g). Most of those in tuna come from protein.
More in salmon: vitamin D (11×), pantothenic acid (10×), thiamin (11×), vitamin B6 (2×) and 6 more. More in tuna: selenium, niacin, iron (4.9×) and sodium (3.6×). Everything else is within 4% of a day's needs.

Where they differ
Bar length is the share of a day's needs (FDA Daily Value) in one serving of each. Every row uses the same scale, so a short difference in length is a small difference. Color says which food, never which is better.
