Want to pass on that a previously flourishing population of curly leaf pondweed is nowhere to be seen several years after adding the papershell crayfish to the 1 acre pond. Other factors could explain this like the emergent plants and waterlilies, but the crayfish seem like the most likely reason. When it cools off this fall, I need to see how big the SMB have grown. Did not fish in this pond at all last year but a neighbor caught a nice YP.
