If you eat salmon, you are hopefully already mostly eating salmon sourced from the wild, which is very rare to come by these days, but will be wild if you get Alaskan or sockeye since Alaska has specific rules in place where salmon needs to be wild. Otherwise, choices like "Atlantic Salmon" are virtually sure to be farmed, which has many issues you can look up.

Another issue that may arise in the coming years is these GMO salmon currently grown indoors in Albany, NY may get out into the wild, interbreeding with salmon in the ocean, leading to it being a tossup between whether salmon is tainted with the GMO variant or not. At that point, it may be wiser to avoid eating salmon entirely if you want to avoid the potential health repercussions of eating GMO foods.
