now that the Hybrid blue gill are spawning and the trout are not feeding we have an over abundance of the blue gill with no predation going on. Soon we will have what we did not want a stunted pond of bluegill. The hybrids have been a real disappointment. considering putting a couple of northern pike in or some other predator fish, but if the waters are too warm for the trout prob. the same situation with any other predator fish. The pond would be difficult to seine, lots of large stones on the bottom. Maybe large mouth bass would help, they like warmer waters.
