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
diminished omega 3, not 6. you got it backwards.
