The difference between wild and farmed salmon production was successfully profiled and differentiated

New tool for identifying wild and farmed salmon

WORLDWIDE
Wednesday, November 29, 2023, 07:00 (GMT + 9)

Thanks to new analysis techniques, researchers can distinguish between farmed salmon and wild Atlantic salmon on a large scale. Does this make cheating salmon a thing of the past?

The price of wild salmon is higher than that of farmed salmon, which makes salmon an attractive fish for fraud. Consumers today are much more concerned with where their food comes from and choose animals that have had a good life. That makes wild salmon more attractive to them.

Nutritional value

There are differences between the two salmon species not only in terms of life. There are also differences in nutritional value. Wild salmon contains more omega-3 fatty acids and minerals such as zinc, magnesium, iron and potassium.

Distinguish

The difference is clearly visible with whole salmon. Farmed salmon has a pink/orange color while the wild variety is redder. This is due to the difference in nutrition. Wild salmon feed on krill and crustaceans that contain the antioxidant astaxanthin, which causes the red color. Farmed salmon do not ingest this substance. In addition, farmed salmon is larger. These continue to grow because there is always food available. With salmon moths it is much more difficult to see that difference. Although there are various analysis methods for this, they are not suitable for testing salmon on a large scale.

Research

In a new study, a group of international scientists, including from Wageningen University & Reseatch, present the results of a new analysis technique that combines advanced lab techniques with smart statistical tools. They managed to correctly analyze 426 pieces of salmon and call the method 100 percent reliable for distinguishing between farmed and wild salmon. The researchers therefore believe that they can eliminate cheating salmon with this new analysis method.
