get better info on the pond....mine is similar and this time of year black crappie are soooooooo easy to catch that it might lend you believe that the pond only has crappie.

The good thing is this time of year is the best time to thin out crappie by rod and reel. Throw every one of them on the bank or dispose of any way you want.

BTW autumn olive is just honeysuckle. Very easy to control/kill off if you want. Saw down the shoots at the base, pile them up and burn in the spring. Do it before they berry out. Treat the "stump" with tordon or spike and it will not come back

Anything that can fit a baby crappie it its mouth will eat one basically - I see the same thing. Post crappie spawn is a feedin frenzy on my pond along with post bullhead spawn. Bullhead get picked off at a higher rate as the school tighter and cruise near surface where crappie are a bit more spaced out and mid column

You can also trap stunted crappie - cloverleaf in mid depth with tuna can with holes in it for bait
