What is the difference between oil from farmed and wild salmon?

Salmon oil is a healthy addition for your dog. The fatty acids in this fish oil fit very well in a responsible diet. Salmon oil can come from wild-caught salmon or farmed salmon. There are a number of differences between wild and farmed salmon, but the fatty acid composition is roughly the same. There are some concerns regarding contamination and sustainability with wild salmon.

Salmon oil

28 August '23 • 2 min reading time

Salmon oil is rich in the omega-3 fatty acids EPA and DHA. In addition, salmon oil also contains omega-6 and 9 fatty acids. All these unsaturated fatty acids are very important for the immune system and the health of the heart and blood vessels. Salmon oil also promotes a healthy and shiny coat. Plus, dogs often really enjoy the taste of salmon oil!

Benefits of salmon oil for dogs

Salmon oil has several health benefits for your dog:

  • Supports coat and skin
  • Stimulates the brain
  • Strengthens the immune system
  • Supports the heart, liver function, and kidneys
  • Ideal flavor enhancer, for example when medication is mixed in with the food

Atlantic salmon

Atlantic salmon (Salmo salar L.) is the main farmed fish in Europe. Most of this farmed salmon comes from Norway, Scotland, and Ireland. Farmed salmon grows faster than wild salmon, resulting in higher production. Additionally, there is no need to fish in wild populations, which is beneficial for the sustainability of the ecosystem. The quality of the fish is equivalent. The fatty acid composition is the same, as well as other parameters such as fat percentage, pH, and texture of the fish meat. However, research shows that wild Atlantic salmon more often contains various contaminants like plastics or heavy metals compared to farm-raised salmon. Salmon are predatory fish; they eat other fish. This means that contaminants in the prey accumulate in the body of the salmon. A predator is at the end of the food chain. Farmed salmon is fed by humans, with feed that is monitored for quality. Therefore, cultivated salmon generally contain fewer contaminants such as dioxins, PCBs, pesticides, and zinc than wild salmon. This is supported by scientific research.

Salmon oil production

The highest quality salmon oil you can give to your dog is made as a by-product of farm-raised salmon intended for human consumption. This salmon must meet strict requirements. The fish is sold to stores and supermarkets, while the oil is pressed as a by-product from parts that do not go to the store. Of course, it is important that the fish farmer treats his fish in a sustainable and responsible way, and that, for example, the antibiotic policy is responsible.

That it has a function besides being tasty? Read more about this in this blog.. Salmon oil rich in fatty acids Unsaturated fatty acids are healthy for both humans and animals, including dogs. Salmon oil is a source of omega-3 in the form of EPA and DHA. In addition, salmon oil also contains omega-6 and omega-9 fatty acids. EPA and DHA omega-3 fatty acids are forms that are easily absorbed and that the dog can use directly. Since the dog cannot produce these omega-3 fatty acids itself, it must get them from the diet. Salmon oil is rich in these fatty acids and therefore a go...
