While wild salmon get their color by eating shrimp and krill, farm-raised salmon generally have carotenoids added to their feed, either through natural ingredients like ground-up crustaceans or synthetic forms created in a lab.

Why is color added to salmon?

Farmed salmon get astaxanthin in their feeds as an added dietary supplement, hence the use of the phrase “color added”. Asthaxanthin provides color to both wild and farmed salmon flesh, but it is also an important nutrient for the salmon, and for humans. In salmon, astaxanthin is important for growth and survival.

Why some salmon is more orange than others?

The actual color of salmon flesh varies from almost white to light orange, depending on their levels of the carotenoid astaxanthin due to how rich a diet of krill and shrimp the fish feeds on; salmon raised on fish farms are given non-synthetic or artificial coloring in their food.

Astaxanthin
Astaxanthin is the carotenoid responsible for salmon’s reddish hue. This fat-soluble pigment is only manufactured by plants and algae and works its way into salmon through diet, including krill and shrimp. Astaxanthin is also responsible for the pigmentation of crustaceans like crabs and lobsters and even flamingos!
