Salmon is a fish specie that belongs to a family called Salmonidae. It’s a fish that migrates and usually lives along the coasts of North Atlantic and Pacific Oceans. Today it is also possible to find salmon in lakes. As salmon is known as one of the healthier fishes in the world, because it’s rich in omega 3, human helps to reproduce salmon in fish farms.
Naturally is salmon produced in freshwater streams and then migrates to oceans. The smolt body chemistry changes allow them to live in salt water. Today we know more species of salmon, which are Atlantic salmon that lives in Atlantic sea, Cherry salmon, Chinook salmon, Chum salmon, Coho salmon, Pink salmon, Sockeye salmon and Danube salmon. Except of Danube salmon, which is the largest permanent fresh water salmonid all other salmon lives in Pacific Ocean.
What do salmon eat?
Salmon are carnivorous and fed themselves by catching other fish and other sea organisms. In fish farms many produced salmon are used to feed other salmon, because they consume more fish than they generate as a product. The massive salmon production result is that values of omega 3 fatty acids are not so high, as we get it from wild caught salmon.
Salmon as a food
Salmon is very popular dish in many cultures because it’s known for its healthy nutrition values. This fish is high in protein, omega 3 fatty acids and vitamin D. Salmon is also a good source of cholesterol. The value of omega 3 fatty acids is a little lower in farm raced salmon than in wild couth salmon. Many discussions have been made which it healthier and safer salmon to eat or a farm raced salmon or wild salmon. Farm raised salmon may not have so high nutrition values than wild caught salmon, but you will not take any risks imposed by contaminants. However it is good to know that majority of Atlantic salmon on market are farmed salmon and that majority of Pacific salmon on the market are wild caught.
Usually the salmon flesh is orange to red, but there are also salmon with white flesh. The color of the flesh is a result of carotenoid pigments. Salmon get these pigments from eating krill and shellfish. There are many alternatives how to prepare salmon flesh. Most known are smoked salmon and canned salmon. However we can prepare salmon like a salmon fillet, salad with ham and smoked salmon, salmon in marinade, grilled salmon, raw salmon etc.
