It’s Not Just Price: 5 Key Differences Between Atlantic Salmon and Wild Salmon.

There are six different species of salmon consumed in the U.S.-Chinook (or “King”), Sockeye, Coho, Pink, Chum (or “Keta”), and Atlantic. Even though they all look similar when they are filleted, the Atlantic salmon fillet is drastically different from the other five species.  When it comes to Atlantic salmon, there are five important differences that most restaurant menus and suppliers don’t broadcast to consumers.

 

1. ALL ATLANTIC SALMON FOR SALE ARE FARMED- RAISED AND MOSTLY FOREIGN.

WHERE DID EVERYBODY GO?

Very few wild Atlantic Salmon exist today.  In fact, they’re endangered in the Gulf of Maine and the GOM fishery for salmon has been shut down since 1948.

Salmon swim upriver to spawn and reproduce but dams have blocked Atlantic Salmon from swimming upriver for decades.

This means that the "Fresh Grilled Atlantic Salmon" featured on the menu never swam in open waters or swam upriver to spawn. All Atlantic Salmon are considered crops at fish farms.

Atlantic Salmon farms are domestically located in Maine and Washington, while Canada, South America (primarily Chile) and Europe (primarily Norway) have many farms.  While the U.S. raises Atlantic Salmon, we primarily don't eat our own crops because consumers’ demand is too great for our country to support. Instead, the U.S. primarily consumes imported Atlantic Salmon. A lot of it!

 

2. CHILE IS OUR PRIMARY SUPPLIER OF ATLANTIC SALMON.

Atlantic salmon are, well, native to the cold areas of the Atlantic ocean.  Yet, our biggest supplier raises these fish in the Pacific ocean.

Total U.S. Atlantic Salmon Imports in 2014 by country, according to the USDA

Chile                       279,004,000  lbs.

Canada                    104,399,000  lbs.

Norway                      57,657,000 lbs.

United Kingdom        34,060,000 lbs.
 

According to the USDA Reports in 2014 , the U.S. imported over 539 million pounds of foreign Atlantic Salmon (valued at over $2.3 billion US), over half of which was imported from Chile.  Meanwhile in the same year, the U.S. exported over 11.5 million pounds of U.S. raised Atlantic Salmon (valued at over $37.2 million US).

IS THIS A GOOD THING?

There is much controversy among farmers and consumers about the aquaculture regulations in Chile.  There is concern on whether the growing number of fish farms in Chile, especially in the Patagonia region, are doing more environmental harm than good (extensive amounts of antibiotics being used, escaped fish, seafloor bottom pollution from accretion of fish waste, wild fish eating farmed fish feed, etc.). There is also concern about regulation enforcement.

 

3. FARMED ATLANTIC SALMON ARE ARTIFICIALLY COLORED.

Atlantic Salmon are available in a variety orange and red hues because they have to be artificially colored.  Just like the paint supply store, fish farmers are given swatches of orange and red so they can choose their ideal shade of fish flesh. How do they get the color? Their diet!

 

WILD SALMON DIET

Wild salmon have pink/orange meat because their diet of krill and shrimp are high in pink/orange pigments called carotenoids. These naturally occurring carotenoids color the salmon's flesh pink (carotenoids in brine shrimp are also the reason why flamingos are pink!).

ATLANTIC SALMON DIET

Farmed salmon are not fed shrimp or krill.  Farmed salmon are fed "fish pellets". Fish pellets are made up of a variety of protein supplements such as fish meals/oils, chicken bones/feathers, and grains that plump up the salmon to market weight in just a few months. To make the salmon's flesh a vibrant, attractive pink for consumers fish pellet producers need to add synthetically made carotenoids to the fish feed (either canthaxanthin or astaxanthin).
 

Without these artificial colorants, Atlantic Salmon fillets would be a dull grayish color. It is mandatory in the U.S. for all Atlantic Salmon labeling to mention the use of artificial colors.

4. ATLANTIC SALMON ARE TREATED WITH ANTIBIOTICS

WASTE

Atlantic Salmon are big fish that excrete a lot of waste! If the cages are not located in an area with strong tides, waste can accumulate around the fish and at the bottom of the ocean floor. To prevent and treat diseases and parasites from waste accumulation, farmers have to incorporate antibiotics into the fish feed.
 

SEA LICE

The biggest threat to fish farms are sea lice.  Sea lice begin life as a louse in the water column. As the louse matures, it will hook onto the Atlantic Salmon and begin a parasitic relationship - feeding off of the salmon’s mucus, blood, and skin. Sometimes, but not always, sea lice can be treated solely with antibiotics.
 

QUANTITY AFFECTS QUALITY

There is concern over the quantity of antibiotics used throughout fish farms.  In 2013, Chile's National Fisheries and Aquaculture Service reported that a whopping 990,000 lbs of antibiotics were used among their fish farms. Meanwhile, Norway grew more salmon that year and required a far lesser amount of antibiotics- 2,100 lbs.

5. ATLANTIC SALMON ARE RAISED IN SMALL CONTAINED AREAS AND IN HIGH DENSITY

All wild salmon are migratory fish and they build up their flesh from intense swimming.

Atlantic Salmon are raised within sea cages, also referred to as sea pens. In each sea pen there are hundreds of fish and very little available space, if any, for open swimming. These sea pens are not designed for animal welfare-they're money makers first and foremost.

CONCLUSION

Now that you know these fish factoids, perhaps you have a better concept of these amazing fish. Next time you see Atlantic Salmon and Wild Caught Alaskan Salmon, you'll know that there are more differences between the two fillets than price. One fish supports domestic jobs and contributes to our economy. The other has a high carbon footprint, was grown in questionable environments, and ultimately devalue our own fish.
