I have 1/4 acre pond that I hoped to use as a forage pond. Some years ago, I rotenoned the pond when a summer drought had reduced it to about half of its full size. I made the mistake of buying cnbg from a fish truck for restocking. Now, trap samplings is showing about 80 to 90% green sunfish. Two years ago, the sampling showed about 60% greenies. I thought greenies only spawned once per year - why such a big disproportional difference ? Anyway, I threw 3 fairly sizable bass in the pond in the the hope that they will eventually spawn and ultimately eat everything in there - (there's a 75% change of a mixed gender pair in the 3 bass). This was probably a crazy idea, but I don't have an easy solution for the problem. Any thoughts ?
