My friend pulled a 6.4 lb LMB out of our 1 acre pond last fall, and a neighbor removes 50-60 eating size BG out per year, all with regular visits from a nearby blue heron rookery. I used to worry about all the coyotes eating newborn deer too. It seems that there are enough of both fish and deer to go around in my neck of the woods.
