I Googled this, as I was curious as well. My understanding from reading a couple of places is that tilapia does have Omega-3, just not in the quantities you would get from salmon, etc. Another good source of Omega-3 is flax seed. You can either look for foods that contain it (Kashi has a tasty Pumpkin Spice granola bar with flax, for example) or you can buy the flax seed and sprinkle it on cereal, etc.
