Guys, please rethink your affinity for Tilapia. Tilapia is generally farmed in interior or exterior pens that are crowded far beyond their natural habits. In short, they eat their own shit more than anything else, with the exception of soy pellets, which is what they are fed (rather than the natural weeds and algae they eat). As a result, they are almost worthless in terms of vitamins: an equal portion of fresh-caught atlantic salmon has TEN TIMES the omega-3s and other vitamins of tilapia. To add insult to injury, their wild acquaculture pens are so foul that they destroy the lakes in which they are loacated AND are invasive speacies, cutting back on the biodiversity and availability of other fish. It is not worth your money in the short term, or your health in the long term.
Buy fresh, wild-harvested COD, POLLACK, OCEAN PERCH, MONKFISH, or HADDOCK (whitefish) or WILD SALMON if you want taste and nutrients at a decent price (currently cod is selling at a lower price per pound that Tilapia in the US northeast). You'll be supporting American fishermen, eating more nutrients per bite than tilapia (or swai), and supporting responsible harvest practices.
End of soapbox....
