Are Norwegian salmon fillets getting paler? Researchers there are poring over pigmentation data to find commonalities in the color of salmon.
Intelligence
The yellow coloration in catfish fillets caused by carotenoids does not affect flavor, but many consumers see the yellowish fillets as inferior.
Health & Welfare
Successful non-invasive predictions of pigment and fat levels in whole salmon were demonstrated by the authors using visible and near infrared spectroscopy to study how these traits vary genetically during growth.
