If you catch any more of the GSF/RES hybrids I sure would be interested to see pictures of those. I would like to see more pics that are certain RES/GSF where your pond never had any stocked BG.
I will certainly keep posting pics as we go along. The kids have caught a couple 10"+ perch and several GSF, but not sure if they caught any hybrids. We will get plenty of fishing in this summer, so I'm sure we will catch several for pics.
