There are slight genetic differences in the Appalachian strain of brook trout. Differences are detected in different watersheds in the southeast. I guess we could call them sub-species. As to poisoning, I watched Kentucky wildlife officers put rotenone in a small farm pond owned by a friend. It was overrun with very small bluegill. The fish came to the top and were netted. One was a huge crappie, the only one in the pond. I don't recall seeing any other kinds of aquatic life being affected. After a certain time period (don't recall what), the pond was restocked.
