This review aims to analyse the use and effects of carotenoids in salmonid aquafeeds. Species of the family Salmonidae are of great interest for aquaculture due to their many properties, like fast growth and nutritional quality. Some species from this family are among the most farmed fish in the world. Thus, there are many studies on different farming technologies, fish biology, market dynamics and others. However, there are always new challenges in the aquaculture of salmonids, being a continuously improving activity. Consumers are becoming more considerate about what they choose to buy and consume. Thus, some aspects emerge as great influencers in the buying decisions of consumers, such as animal welfare, in addition to usual influencing factors, like product freshness and colour. A category of ingredients used in the salmonid aquaculture are carotenoids. They are pigments supplemented to diets for colouring the fish flesh, making it more appealing to consumers. However, some other benefits can also be observed, especially on the health of fishes. Be it synthetic or natural, carotenoids have become a largely used ingredient in salmonid aquafeeds.
