Are farm-raised rainbow trout dyed?
No. • In the wild, Rainbow Trout get their colour naturally when they eat other marine organisms, which contain substances called carotenoids. Farm-raised Rainbow Trout eat these same cartenoids which are included in their feed. One of the cartenoids, astaxanthin, is identical to that which is consumed by Rainbow Trout in the wild, and is a known anti-oxidant often included in vitamin supplements for human consumption. • The other carotenoid used in fish feed, canthaxanthin, is also a natural part of wild trout diets. Is antibiotic usage in farmed rainbow trout high? No. • Antibiotic usage in Rainbow Trout farming is far lower than that of other livestock farming such as pork, beef and poultry. Typically, a very low percentage of farmed fish are exposed to antibiotics: approximately 2-3 %. • As freshwater aquaculture has evolved, food formulations have improved, as have husbandry practices, and these realities have contributed to a steady decline in the use of antibiotics. • Some trout
