Default Wild salmon vs farmed

Here's a scary thing, marginal to this discussion: On a Nova show last
year, they said that some killer whales' body tissue contains so much
toxic crap (by parts per million or however it's measures) that if the
animals were land-based waste, they'd be subject to special handling by
whoever needed to discard them. I'm sure the fish we eat don't have the
same issues, though, because they swim in special water, unlike the
whales.


Has to do with age more than size. Longer lived, more concentrations.
halibut of 200# are almost not sellable by the commercials. To much
mercury. The buyers want the 60# and less. As to the Mercury, most is from
China and all the coal they burn. That air pollution has to go somewhere.
