If your goal is trophy LMB I would try to leave the CC out just to make things a little more simple. I have a few CC in my 2 acre pond. I would rather not have them there but I don't think they make a big difference. At greater numbers they will make a difference on forage. When I feed My BG the CC always show up and bully the feed area.

The bottom line with me is that they are not a fish I target for sport, I don't eat them, and they compete with all the sport fish for Oxygen, food and space. For my pond they were a bad choice. Not a terrible choice but probably not an optimal choice for my goal which is trophy LMB.

Oh... and once LMB get above 16 inches they will do a great job with helping you control the LMB population. you will still have to do a lot of "work" removing eneough LMB each year but the LMB will help.
