My ponds are primarily for wildlife, so I don't mind sharing the fish with whatever shows up. I do take exception to beavers clogging the drain pipe. Need to place large chunks of concrete around pig-panel guard to keep them from digging under it. Bricks are not heavy enough. They are persistent critters! Not happy with them cutting bald cypress either. Fortunate that neighbor trapped out 4 in the last week. Might still be one left, but we will see if drain continues to be blocked. Clearing it every day is no fun.
