The importance of carotenoids in aquafeeds
Carotenoids are important pigments that contribute characteristic quality criteria for the marketing of aquaculture products. Aquatic animals cannot biosynthesize carotenoids de novo, hence their inclusion in aquafeeds is important because they are associated with various metabolic functions.
