16 pike and 1 pickerel on the water somewhere in the state with an unknown lure

[FishinFool247]

Decided to go fishing yesterday after work and I was quite happy I did. I was thinking about staying home because of the high temps but it didn't affect the fishing one bit. I caught 16 pike and one pickerel in about two hours between 4:30 and 6:30. I caught 9 pike in a row in the same hole without moving my feet other than to take the fish off my line. I thought to myself how and why are there that many pike in one hole and how they are being able to feed being that stacked up in one area. I feel as if there is too many large fish in one area for them not to take a serious toll on all of the other species of fish in the area. Does anyone else feel that this many fish in one area can be unhealthy for the overall health of the river on a whole? Unless the pike are feeding like bluefish going after schools of bunker, I really have no idea why there would be so many pike in one area.
