there is an atricle in Dakota Country Magazine titled the Perch/Bluegill Connection by Mike strand Outdoors.
Now granted this article is about bigger bodies of water and fishing not just fish managment, but the principles may still apply. His theory is if you find Jumbo perch in a lake than there are also big Gills (should BG be present).
His theory is that once a perch reaches 8" it can become a baby bluegill eating machine, keeping them from overpopulating. And the perch eating their own young too.
He also states that perch and BG live in different areas of a lake with perch generally being deeper, they just need to come in to contact at certian times during the year.
The catch in his theory is that the lake has to be a natural producer of big perch for them to properly regulate the BG.
That being said if there are bass in the lake to help regulate the BG and perch them selves it should even things out well (in my perch loving opinion).
I have no idea about feeding pellets to wild fish, but htat would definatly fatten things up all the way around.
