New research shows surprising differences between salmon species

Updated: May 14



As I was shopping at Costco Canada, I came across an "organic" labelled salmon. This was a great find, so I thought I would share this find on my Instagram story. I quickly received a person's message stating that "Organic doesn't mean wild, it just means fed organic food. Unfortunately, this is still terrible salmon! Not to mention the negative impacts open-net fish farms have on ocean environments."

So I decided to do some research on these topics. I came across the Journal of Agriculture and Food Research article investigating the nutritional composition of different salmon types available to Canadian consumers. (Dated December 2020)


Salmon is well known to provide a range of valuable nutrients, including omega-3 fatty acids and protein. However, it may not be evident to consumers to know which species offers the highest nutrition level when faced with several salmon types in the grocery store.

Some people believe there are mixed messages regarding farmed (organic labelled) salmon that may contain contaminants and are not as nutritious as wild fish.

Consumers cannot rely solely on labels for clarity, as nutritional information on seafood packaging in Canada and the United States is not required.

Stefanie Colombo, an Assistant Professor of Aquaculture at Dalhousie University's Agriculture Campus, wanted to shed some light on the muddy area by exploring the nutritional differences between salmon types. Her research, recently published in the Journal of Agriculture and Food Research, has produced surprising findings that she hopes may dispel misunderstandings about farmed salmon.
