Doug wrote:Your post clearly speaks about BALANCE, and that is my exact point. Right now there is an observed imbalance in the lakes in this area, with far too many sunfish for the carrying capacity of the water. For example, most of the lake trout (top predator) caught in Loughborough last winter had large heads and skinny bodies, ie they were slowly starving. SOMETHING is eating the food that the lakers usually eat. And it was reported to me by several anglers that quite a few lakers they kept had sunfish in their stomachs. In the past, this would not have been the case, since sunfish are not a preferred forage for lakers and typically inhabit shallower depths than would be the norm for lakers. (Of course, lakers do come into the shallows in winter, but you get the idea.)
So I surely agree that a lake with a preponderance of large fish is not a healthy body of water, but that just is not the case in any lake here of which I am aware.
Sorry for sounding like a broken record, but I do think it is important for us anglers to understand the ACTUAL situation, not a theoretical one.

Doug, lakes are ecosystems, and like all ecosystems every organism plays its part. When you remove any one of those parts you change the ecosystem, which effects all organisms in that ecosystem.
Panfish and Lake trout have differing places in an ecosystem. Because panfish are smaller and more abundant, more organisms in an ecosystem rely on them for sustenance. For example, birds, mammals, reptiles, other fish feed on panfish. In turn Panfish feed on invertibrates, smaller fish and the eggs of other species.
Predatory fish such as Pike and Lake trout serve the purpose to keep panfish populations in check.
If you remove panfish from an ecosystem, you are not going to have more larger fish. You are going to have no fish! because panfish are apart of the base in an ecosystem that supports larger predatory fish to exist!
