Yellow Perch. They're usually a mixed bag of sizes. I organize the stocking of a 70 acre lake we live on for our association. They've come before with mostly little ones and they've come with borderline jumbos with smaller ones mixed in. They can fit a lot of little ones in a gallon bucket before they put them in the bags. Was $35.00 a gallon a couple years ago and the WE were 50 cents apiece for a 4-6 in incher. These guys do a better job producing fish than the Mn DNR.
A few years back some/one of their brood stock lakes had a very high water level and made it into the 33' legal road easement. Lets just say the locals took advantage.. Multiple 9 to 11 pound WE were caught. It was a big story in the news around here because they couldn't do anything about it. I heard they would dump tons of minnows in their lakes when their minnow ponds got overpopulated...
I might have to up the amount of minnows I put in.
