BASF recommends Lucantin® Red (canthaxanthin) and Lucantin® Pink (astaxanthin) for aquaculture. Generally, when products are added to a formulation preextrusion, the harsher the feed process, the more carotenoids will be lost. Lucantin® Pink and Red are available in the form of dry powder and CWD. The dry powder form should be used preextrusion and the CWD-formulation postextrusion.
Red pigments play an important part in the underwater world. Many fish need them for camouflage and communication, while others further up the food chain require them to stay fit and healthy. We instinctively prefer a piece of vividly pink salmon to another, paler one. Because fish and crustaceans living in aquaculture cannot feed on carotenoid-containing algae and fish, they have to be provided with additional pig-ments in their feed. In other words, aquaculture farmers who want their salmon, trout and shrimp to have the desired high-quality color have to give nature a little boost.
