H2O, I watched and electofishing demo by the state DNR at a 1 acre pond that was completely surrounded by cattails and crystal clear. Several skinny bass, one big CC, GSF, BG, Pumpkinseeds, and a few sunfish that looked like a combination of the other species were shocked and netted. The DNR said that the sunfish interbreeding was due to a lack of breeding partners in their own species because of the bass being overpopulated.
