More common than you realize. In my personal pond, I fight it constantly. C&R is nice, but LMB can overeat their food source pretty quickly. It takes approximately 10 pounds of fish to put one pound of weight on one LMB. That's why pond owners with LMB in their ponds need to stay on top of them and watch their condition.
