Should You Avoid Farmed Fish?
Seeker・3 minutes read
The demand for fish consumption has led to aquaculture surpassing global beef production, with farmed salmon being fed smaller fish like sardines and anchovies to achieve their distinctive color. Some salmon farmers replacing fish oil with vegetable oil in feed may result in an unhealthy fatty acid balance, impacting both the fish and consumers according to a study by Norway's National Institute of Nutrition and Seafood Research.
Insights
- Farmed salmon's color is achieved by feeding them smaller fish with carotenoids, unlike wild salmon.
- The substitution of fish oil with vegetable oil in salmon feed can impact the fish's fatty acid balance, potentially affecting the health of consumers, as highlighted by a study from Norway's National Institute of Nutrition and Seafood Research.

Aquaculture Surpasses Beef; Salmon Feed Concerns
- Fish farming, known as aquaculture, has surpassed global beef production in 2012 due to the high demand for fish consumption.
- Farmed salmon, unlike wild salmon, are fed with smaller fish like sardines and anchovies to achieve the orange-pink color from carotenoids in their shells.
- Some salmon farmers are replacing fish oil in feed with vegetable oil, which may lead to an unhealthy balance of fatty acids in the fish and potentially in those consuming it, as shown in a study by Norway's National Institute of Nutrition and Seafood Research.
