Ok, well, in 3 hours with 5 minnow traps, I was able to remove ~375 PS.
My big concern is I didn't see one YP. Just PS and shiners in the traps.
This past weekend I threw a trap in and looked quickly at the fish, the very small PS fooled me into thinking they were YP, because of the vertical stripes, upon closer inspection, I realized they were all PS.
This means the 50 YP I put in last May did not spawn this year? What would cause that? I have not really seen any of the YP since I put them in, but I never found any dead ones either...
Here are a couple pictures showing the size range of the PS.
EDIT: Hicklings say they have plenty of 4" SMB.
