Let's face it, our bodies need a variety of sources of high quality lean protein, with out all the saturated fat traditional protein sources offer us. Throw salmon into the equation and in addition to a high quality lean protein, we find a source rich in Omega 3 Fatty Acids, which are essential to our bodies brain functioning and cardiovascular system (in addition to numerous other health benefits). Often times people suffering from lifestyle induced heart diseases are lacking in Omega 3 Fatty Acids. Salmon should be a part of your diet.
But are all sources of Salmon safe and equal? Unfortunately, they are not.
Farm Raised Salmon, Hidden Dangers:
High levels of PCB's, dioxin, and toxins are found in farm raised salmon, mainly derivative of their fish meal diet.
Pesticides are also found in the flesh of farm raised salmon. They are used to control parasites such as sea lice, but are regulated to not be administered 28 days before harvest, to help avoid a build up in high levels. So why are they still found?
Unfortunately one day a scientist discovered that farm raised salmon's natural grey flesh turns the "normally associated" pink tone when fed a chemical called canthaxanthin. The chemical has been linked to retinal damage and banned in Scotland and Europe. Farmers carry charts as seen below, so they can decide how pink they want their farm raised fish to be. Nice touch, huh?
The fat content of Farm Raised Salmon is 11%-20%, with some of that fat being higher levels of saturated fats, and ironically enough lower content of Omega 3 Fatty Acids.
Wild Salmon, Obvious Choice:
Unlike it's faux counterpart, Wild Salmon contains 7% fat on average, with much higher levels of Omega 3's, with out elevated levels of saturated fats. Wild Salmon also contains some of the lowest levels of Methyl Mercury which is also a concern with fish these days.
Oddly enough the Wild Salmon season is Mid-May to October, even though you will find Wild Salmon other times through out the year. Please be weary of those sources of salmon, as farm raised can be brushed off as Wild. Trust your fish monger.
Our natural fish sources are being depleted. The majority of Alaskan salmon (safest source of salmon) is highly regulated to maintain sustainability. Once quotas have been met, harvests are closed. Biologists are working with fishermen to help keep the sources safe from depletion.
Higher Cost, a Couple of Solutions:
As you can imagine, Wild Salmon is going to be more expensive than farm raised salmon. Two things I suggest, buy only the amount of salmon your family would consume in one meal. We typically don't eat left over salmon, which in turn is a waste of money and natural resources. If at all possible underestimate the amount you will need and make due!
Secondly, try frozen Wild Salmon filets. The cost is going to be cheaper when you buy it pre-packaged in the frozen section. Try to stay clear of previously marinated filets, they are typically high in sodium, and you are better off seasoning the fish to your family's taste anyway. I know Costco sells Wild Salmon FROZEN for about $7.99 lb.

In closing, please remember to not confuse wording. Fresh does not mean wild, it just means not previously frozen. Many restaurants use Farm Raised Salmon, so pass on it. If they aren't advertising it's WILD, simply ask. Keep an eye out for the Marine Stewardship Council Seal, you'll find it on menus and in grocery stores.
