Ed has it right. those die hard perch guys fish for them commercially. If you can keep 50 2lbers at 3.50 to 4 bucks a pound, thats some decent cash. and those guys are that good. They wont tell you a thing.
in May I wail on em right off my dock, big ens jumbos slabs, but once the water temp gets up a bit, they take off and I'm left with the dinks for the rest of the summer.
I dont bother with them after i put 2 packs of fillets in the freezer anyway.
