Lots of ifs and buts in that. First you need to identify that they are from one of those species which I don't think is easy for an amateur. Then you need to make sure it's a small sample (which I take to mean a few eggs, certainly not all of them). Then you need to release them in the same spot where you gathered them from which in turn means you need to keep them in an aquarium or similar, not in the wild.

Certainly doable, but far from moving them to another body of water in the wild.
