If the environmental concerns alone aren’t enough to make you want to steer clear of farm-raised fish, perhaps the health concerns will be.
Studies have consistently found levels of PCBs, dioxins, toxaphene and dieldrin, as well as mercury, to be higher in farm-raised fish than wild fish. Further, farm-raised fish, like factory-farmed meat, is pumped full of antibiotics, hormones and even chemicals to change their color (such as to make salmon appear pink).
Sadly, contamination of our oceans and waterways is so great that toxic pollutants have been found in wild fish as well, and this is why I don’t advise eating any fish, whether farm-raised or wild-caught, unless you can verify its purity.
What options do you have, then, to get the health benefits of the omega-3 fats in fish, without exposing yourself to pollutants or contributing to the decline of the fish population?
There are two ways. The first is to track down a source of wild fish that is free from toxins, and which is sustainably harvested. After years of research I found one such company, Vital Choice, which offers salmon with no harmful mercury or other toxin levels and which works closely with a native Alaskan tribe to ensure the salmon are sustainably harvested during their migration.
The second option is to get your omega-3 fat from an alternative source like krill oil. Not only are krill (small, shrimp-like creatures) a superior source of omega-3, but they are one of the most easily renewable food resources available, making them an excellent nutritional source from an environmental perspective.
Though I know many of you enjoy fish for the flavor and the health benefits, if you can’t confirm that it’s from a clean, sustainable source, I believe the risks from eating it -- both to your health and the environment -- vastly outweigh the benefits.
