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.
diminished omega 3, not 6. you got it backwards.
There are some GMO plants that like camelina that synthesize DHA/omega 3s and a soybean that produces other long chain SDA which are omega3 DHA/EPA precursors, which could be used as farmed fish feed to help get them back to natural 3:6 ratios but the govs make it hard so they keep making unhealthy fish and feeding bycatch
Herring is also a major staple food for us on the east coast of Canada. Stocks of Mackrel are at the lowest points ever recorded and the fishery has been shut. We all know about cod and Wild Atlantic salmon almost do not exist. Yet we are allowing ocean based fish farming companies that were shut down elsewhere to open all over the place here. Our politicians are courting these environmental disasters to create a minimal volume of low paid jobs in favor of destroying the very thing that keeps humanity alive. It’s insane.
