I figured correctly that there would be some interesting discussion in this thread.
Eric's "establishing a viable GShiner population" post is something I would consider doing in a separate pond. Thank you for the concept! I am not willing to submit Bremer Pond to that level of human intervention. Keeping things as "natural" as possible has always been my pond credo. A FH pond sounds interesting too.
Did I mention that my brother-in-law may be "storing" his track hoe out here this summer......
