IMO there is a big difference in taste collor and texture in the flesh of a wild salmon/trout vs a farmed.
Also the farmed contains only 30-50 % of the healthy Omega3 fat, and I'm not talking about a poorly farmed Salmonid.
It dosen't mean it taste bad but surly different.
I hardly eat any other farm raised species living seaside you get wild caught, but wild caught salmon are far between, and hard to come by unless you catch it your selfe around here.(now days)
Suplemental feeding in "natural" ponds, are different than intensive feeding in chages/pens/raceways a diverse (natural) diet gives the natural variation on the fish.
