Do you have Gambusia minnows? They help jump start the small bass population , but lots of folks don't like them . I have them and like what they add to the forage base. Next your LMB will work on your CNBG YOY
I dont have them in the pond now but I can net some up because they are in about every BOW here in FL. They have been in my grand fathers pond long as I can remember so I know they will stay around. As for the CNBG there are tons of rice size fry swimming around now from this years spawn and some 1.5" so that should take a lil presure of the FHM, plus they are pellet trained
I would use sail fin mollies in stead of the GAM's just as easily available but get about double the size and offer a much better forage for a shallow surface minnow. You can find them in most ditches etc... They are live bearers just like the gams too.. They are much less aggressive at eating new hatched fry also.
I would skip the gams if you can avoid it...Although I would not be surprised if you did not have a few in your stockings as hitch hikers...
tilapia are also in just about every body of water around you...they find a way. I have seen ospreys carrying them in the sky...IF one dropped a large female that was holding babies in its mouth in your pond then you would have them...
