Novel sources of EPA and DHA, such as genetically modified oilseed crops (canola/camelina) and microalgae, can fully replace fish oil in aquaculture feeds without negative impacts on fish growth or health.
Look for farmed fish fed with novel Omega-3 sources (algae or GM plant oils). These products often have higher or equal Omega-3 levels compared to standard farmed fish and support sustainable fishing practices.
GoodSupportsHIGH confidence
the modified camelina oils have been used to replace both fish oil and vegetable oil, showing that they can directly replace all the added oil in feeds without negative impacts on fish growth or health.
Why this rating
Based on multiple feeding trials cited (references 48, 49, 63, 80, 82, 81, 83, 84, 57, 58).

More from this paper
- Current global supplies of EPA and DHA from traditional marine sources are insufficient to meet human nutritional requirements, creating a supply-demand gap of over 0.4 to 1 million tonnes annually.Good
- Replacing fish oil with vegetable oils in aquaculture feeds reduces the EPA/DHA content of farmed fish, negatively impacting the nutritional quality for human consumers.Good
