The salmon I'm buying comes from a land based farm in Hirtshals, Denmark (see e.g. https://reasonstobecheerful.world/for-a-new-generation-of-fish-farmers-the-ocean-is-becoming-obsolete/ ). I'm trying to track down what kind of feed they use. In theory they could e.g. farm black soldier fly larva, but I doubt their pellets are 100% fish meal free. I guess I just should contact them to find it out.
Yes, this is a good idea. Farmed salmon in the USA was fed in such a way that they had much diminished Omega-6 content versus wild-caught. However, I am not sure if practices have changed since I first looked into it, which was in the later 2000s. It is harder to track down suppliers to verify in the USA because of the supermarket phenomenon here.
