ewest, I also doubt that all of the BG died. But if the pond was stocked with CNBG and the LMB were all Northern strain, a large population of the BG could have perished.

I'd suggest either running a seine through the pond to assess the fish population, only stock adult BG, or Rotenone it and start fresh.
