Carotenoids are important for immune defense. Carotenoid limitation is frequently cited as physiologically important, but few studies have tested this in the field.
We found that dietary carotenoids facilitated recovery from bacterial infection in convict cichlid fish in the laboratory, but that field populations were not limited by access to carotenoids.
