Is this wonder food too good to be true? Not necessarily, but just like there are precautions when enjoying meat there are things consumers need to be mindful of before feasting on fish.
Overfishing can cause the breakdown of sea ecosystems. Fishery management mandates have been implemented in recent years to try and prevent the breakdown, and the extinction of some species. Fish farming – raising fish in tanks or enclosed areas – has been said to be more sustainable. However, this comes with it’s own host of problems.
One fish in particular that’s caused some alarms to go off is farmed salmon. I count salmon in my list of top 10 favorite foods so this pains me! But, you just have to be aware of where the fish came from…
What’s the environmental impact of farm raised salmon?
-Fish parasites can easily run rampant in salmon farms.
-Farm runoff has been linked to increased mercury levels neighboring wild fish.
– Toxic fish feces, copper, and zinc can contaminate the waters surrounding salmon pens killing other species.
Sportsfisherman.com reports that it takes two to five kilograms of wild fish to produce one kilogram of farmed salmon.
What are the health affects?
-Farmed salmon contains high concentrations of polychlorinated biphenyls (PCBs) and other dangerous contaminants, and the widespread use of antibiotics and pesticides may lead to the emergence of antibiotic-resistant bacteria.
– Plus, it’s dyed “salmon” color because its natural color would be grey from it’s artificial diet. Not so appetizing.
-Scientists have found farm-raised salmon contain more cancer-causing PCBs and dioxins than wild ones do, typically originating in their feed. It’s estimated that the risk of cancer from contaminants is about three times higher for farmed salmon than wild.
Bottom line? Eat fish in moderation, enjoy wild and if you are a fisher please catch and release to help cut down impact!
