Our local health food grocery has primarily 'organic' or 'sustainably-farmed' farm-raised salmon. I've been unable to find out what this means, exactly (besides claims that they don't use antibiotics etc), but I'm guessing that they are still grain-feeding them which makes them crap for proper omega-3 levels.

I've googled a bit but come up dry - does anyone know about the omega-3 levels in organic farmed salmon?
