Farm-raised Atlantic salmon typically has color added to its feed, such as beta-carotene, to achieve an orange hue.

“wild salmon is much more orange and the farm-raised salmon is much lighter in color”

“this farm raay salmon is actually this color but they add color to it to make it look like wild salmon”

“But this Atlantic salmon doesn't look like this color unless it's fed beta-carotene in the feed.”

“Asisanthin is a carotenoid used in the feed of farm-raised Atlantic salmon. It is in the same family as vitamin A. Corotenoids are part of the natural diet consumed by salmon in the wild and give salmon its distinctive color. This is Atlantic salmon. So they're giving the salmon asanthin to get its color, but the salmon is not eating krill. It's not eating its full diet.”

“So farmraised salmon is actually this color. It's actually stark white because it doesn't eat krill. It doesn't get the aisaanthin that wild salmon gets.”

“it's famous because it's what's turned salmon pink the reason that if you want to make your farm farm grown salmon pink you dump tons I mean tons you know dump truck loads of acanthine into the water”

“MAny of farmed fish lack astaxanthin & synthetic (which has weird isomers) is added.”
