Update: I was able to remove one of the LMB with help of my 12ga and turkey loads. However the other know LMB I was not successful in my attempts. Today I was at the pond and noticed what looked like a few hundred fry that I can only assume are LMB based on their slender shape and proximity to one of the LMB beds (the one I didn't get). I also discovered two large male BG that also were bucket stocked before the renovation that appeared to survive. They were guarding beds. Not sure if any female BG were present to lay. These two fish were brutes compared to the size when I put them in a couple years ago. So it looks like I'm well on my way to a BG and LMB pond. It will still be enjoyable no matter the fish species. I'll be curious to see how the SMB fare over the next couple years.
