Reading through the threads on this forum, I see that the focus is primarily on White Perch & Yellow Perch. I don't believe that we have either in Oklahoma (though I could be wrong).
The fish that is generally called a "perch" around here is the Sun Perch, which I've also heard called a Bluegill.
Anyone else here fish for these guys? In my experience, they're biting even when nothing else is. They'll bit on jigs, minnows, worms or pretty much anything you throw at them that they can get into their small mouths. They're a lot of fun to catch because the fight is disproportionate to their small size. Generally they're only a pound or less, but I've gotten into some bigger ones from time to time. I've been told that they're pretty good eating as well, but I've never bothered to find out for myself, seems more trouble than it's worth to fillet the little guys. They're a catch & release fish as far as I'm concerned, but they can sure make your day when you get into a bunch of them when nothing else is biting.
