Schneider's Oh Naturel Meatless Burgers?

I have the Schneider's Oh Naturel Meatless Burgers. I noticed that they use omega 3 and omega 6 so I would like to know if the omega 3 comes from fish or if it comes from something else like nuts. I am a pure vegetarian so I don't eat eggs or fish or anything else. I wanted to know if the omega 6 and omega 3 are fish and egg free. Thanks.
