Farmed salmon is generally raised in two stages. First, the eggs are hatched and raised on land in freshwater tanks for 12-18 months, producing smolt (juvenile salmon). The smolt are then transferred to floating nets or pens in the ocean, where they are fed pellets and grow for another year or two.
How is farmed salmon made?
Farmed salmon begin their lives in hatcheries. When they are born, they are raised in freshwater tanks for up to two months. After a year or so, they are transferred to sea cages, where they are fed commercially-produced fish food often made of wild-caught fish.

Is Costco salmon farm raised?

Is farm raised salmon dyed?

Why is farmed salmon grey?
Wild salmon gets its distinctive pink flesh from a substance called astaxanthin, a pigment found in shrimp-like krill and other crustaceans that the salmon eats. The Four Corners program revealed that farmed fish are often fed a synthetic version of astaxanthin, without which they would be grey or off-white in colour.
What is the best tasting salmon to eat?

Why is my salmon white and not pink?
White-fleshed king salmon don’t have the genetic ability to break down their food and store the red-orange carotene in their muscle cells. The marbled flesh color sometimes found in king salmon comes from their limited ability to metabolize carotene, causing the flesh to take on a marbled look.
How are farmed salmon killed?
Salmon are usually killed by administration of a gill cut to exsanguinate (see text box 2) after the percussive stun. Decapitation can also be used to kill fish that are unconscious following an effective percussion (see text box 3).
Does farm-raised salmon have parasites?
This is because farmed salmon are exclusively fed strongly heated and processed dry-feed which therefore cannot contain parasites such as Anisakis. In 2015, the Norwegian Institute of Marine Research examined 4,184 farmed salmon from 37 salmon farms and did not find any Anisakis.
