Where did all the Hogs go?

We fished Hillsdale a week ago on Thursday and we caught 30 nice crappie, 20 of them between 12" and 13". The rest were all over 11". Went back on Friday and got 15 more all about the same. Returned on last Tuesday and got 24 more of the Hogs! We caught them all on minnows and mostly 14 -18 feet deep in 20 - 25 fow. Had the best luck dippin the trees. Fishing at that depth we caught only a handfull of Dinks!
So we went back yesterday and tried the same thing. Ended up with 19 keepers, but none over 11". And we caught about 30 little ones. So where did the bigger fish go?
The more I fish HD the less I know about crappie!

sounds like they went under the knife

The more I fish period, the less I know about crappie.

Pretty much the same story for me yesterday?

I think they might be done spawning, what a bummer! Its nice not to haul the boat and just fish off the bank sometimes. Tight lines
