Does anyone have any information on getting a population of freshwater shrimp started 30 miles or so south of Lake Erie in PA? I would like to get them established in my pond prior to adding any larger fish as additional forage. My hope would be a self sustaining population.

I added my fatheads today and am planning to add papershell crayfish as well, the shrimp would be a bonus, as are the tadpoles that are everywhere, unless the perch won't eat them, in which case, I have lots of frogs coming along.
