[quote name='kodave']I'd love you see your source on that cancer risk theory. Never heard that before, and quite frankly, I don't believe it.
None the less I agree about eating wild fish over farmed fish.
At least when it comes to salmon, the most common type you see out there is the farmed Atlantic salmon. And to me, that tastes like rubbery shit. I can't eat it unless its heavily coated in something or mixed with something else like crab meat. I try hard to avoid it, both at home and in restaurants.
During the summer, Costco actually offers a nice selection of wild steelhead salmon that hasn't been farmed (though they often have the farmed variety too along with the farmed Atlantic salmon). The strange thing is, I believe the wild steelhead is priced cheaper than the farmed Atlantic crap, but whenever I'm there, tons of people are always scooping up the farmed Atlantic salmon.
Unfortunately I've never seen wild salmon at any of my local grocery stores. Just the farmed Atlantic crap.
And from what I understand, wild or farmed, the fish all have color added to them. Its just like every fruit and veggie you buy from the store is covered in wax and has other preservatives added to maintain its color. I've never seen anything that indicates the color additives are bad for you. With fruits and veggies, its my understanding the big concern is pesticides which is why some people choose "organic" instead of the regular variety. With fish, like I said before, you have to watch out for stuff like mercury contamination. But I've never heard about any serious concerns or problems with color additives.
Here is a guide for eating fish that considers health and ecology:

Its from an environmental group so you may not like their taint, but I've seen similar charts issued elsewhere. Just Google for them.[/QUOTE]
Steelhead are in the salmonid family but they're basically just sea run rainbow trout. If you do a quick google search on what the EPA recommends as the maximum limits for pcb toxins in fish you'll see that the epa which only looks at health risks to humans level is 40x lower than what the fda allows in the food supply here's the epa's report

And as someone who worked for six years in a fish market/processor I have filleted and steaked thousands of salmon both wild caught Alaskan fish when in season and farm raised atlantic; the farm raised fish are always highly deformed most the time due to massive inbreeding and poor living conditions. And only farm raised fish are colored through special feed additives not wild fish. I've seen countless people in the past when working in the market that turn their nose at wild Alaskan salmon because the fillets don't look as nice and the color seems 'off' because people are accustomed to artificially colored salmon as being the way salmon should look. And any fresh fish you buy in the store even if your right near a coast like I am is usually between 3-5 days old once it even gets to your average supermarket; which is why I advocate if your not near the source your fish is coming from or not catching it yourself to buy it frozen if possible and avoid fresh. The key to this also is pay attention to where the label tells you the fish is from the government passed a law a few years back that requires the country of origin to be stated on seafood and method of origin fresh/farm raised to also be listed. I would avoid at all costs any fish labeled as coming from China personally and I see frozen fish labeled with this becoming more and more common.
