I believe that the search will reveal no difference in fecundity of black and white crappie. It's usually considered only a matter of time before they overspawn. The result will be a water hole full of stunted fish. Yep, they will do a number on CNBG.

As far as I know, there hasn't been a really effective predator identified that can keep up with their numbers.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.

Without a sense of urgency, Nothing ever gets done.

Boy, if I say "sic em", you'd better look for something to bite. Sam Shelley Rancher and Farmer Muleshoe Texas 1892-1985 RIP
