Pond Boss Forums MANAGING AN EXISTING POND Evaluating and adjusting fish populations Fin Clippin

I spared no expense and bought a $3.99 single hole paper punch at Staples. As the years go by I will punch a different fin. It works too. Last week I caught a blonde female BG and punched a hole in her fin. How do I know she was a blonde? I caught her again 15 minutes later. The only 8" female in the pond with a hole in a fin.
