Here is some of the "rest of the story".
Also note the fish of CNBG listing is said to very likely have mixed species of BG and RES and maybe even some hybrid BG(HBG) could be present.
Bill are they saying that their fish production ponds are contaminated (multi species and crosses) ? Yikes !
RES and BG yoy growing out in same pond is ok.
Providing you are not stocking a pond with strictly SMB as a top end predator.....
I have a pond that is like that and now BG are starting to show up. So a mad scramble is on to try and limit their numbers. There were HBG stocked along with RES. The HBG were all hand sorted and 6 BG were pulled from them before they were stocked in the pond. The RES were just stocked, and I think that is possibly where they came from. No runoff or water from another BOW or creek can enter the pond.
I will be spending a lot of time at this pond on my dime this year seining, trapping and angling to remove any BG that can be removed.
