Salmon Is White Fish in Spite of The Red Color.

What color is salmon in general?

Why is salmons orange even though they are white fishes?

Everyone thinks the color of salmon is pink or orange.

However, salmon is classified as a white fish.

The bright color of salmon is the color of plankton.

Salmon have a habit of taking plankton into the body and strengthening the body for spawning.

A substance called astaxanthin contained in plankton that salmon eats as food is pigmented in the body.

Astaxanthin is also the reason why their roe has a similar color to bodies.

Astaxanthin protects the contents of eggs from UV rays.

The orange color of salmon is pigmented by plankton after birth.
