Pickerel Slaughter

[AtcoSteve]

A few weeks ago I was desperate for a fish so I went to a local lake to wet a line. In about an hour I caught four pickerel. As I was leaving a truck pulled up with a local guy inside asking " What ya get", I told him about the pike and he asked me If I put them back in alive.
I answered why wouldn't I. He then went on about thinning out the population so the bass could get bigger. He even threw in a sentence about taking the smaller bass out.
Even tho i understood the concept I was always taught "Catch and Release"
Just wanna know what you guys think.
