Mullyden,
I stocked 50 4-5" CC in late 2005 after my 1 acre pond was started. I caught about 10 12-20" CC often during the first couple of years on BG or LMB baits but rarely attempted to fisn the CC but still caught a few on nightcrawlers. I only kept 2 of the CC. Over the next few years, I would see a couple of CC feeding to seeing none over the last three years. I suspect a neighbor fishes while I'm not at the pond site but really am in the same boat as you with wondering where they went. I've tried to fish for them 3-4 times right before dark over the last 3 years because I found out they are piscivorous after a couple of years and caught nothing. My wife caught a LMB on a piece of hot dog but no more CC.

BTW... My pond is in between Poplarville and Lumberton. Where about are you?

1 ac pond LMB, BG, RES, CC
