Quarteracre - As mentioned by 'jpsdad' add one CC that is big enough (maybe 15"-17") to right away start eating your adult crayfish. Then monitor cray numbers to see if it helps over the next few years. I would not add more than one CC into my perch pond because I don't want any CC reproduction. From experience CC do eat a significant number of YP. Then if you decide to remove the CC fish with crayfish as bait.
