gotta watch out for mercury poisoning tho if you eat too much fish.
from what i read it's the "farm raised" salmon you have to worry about for mecury poisoning.
basically farm fish get grown, are given "feed" and live for 2 years on feed. So then they harvest these 2yr old fish that eat nothing but feed. They filet them and send all the "unsellable" to the grinder. Fish heads, spine, fins, guts. They grind all this up and make "feed" with it. So they feed the new fish old fish, which wouldn't be bad, but they're compacting so many fish into "feed" that it's compacting the mercury. Cuz all fish have mercury it's just that farm raised fish are getting concentrated levels of well, their cousins.
